Pivot Point in Blender: All You Need to Know (2025)

If you are new to Blender, knowing how to perform object transformations is essential. Rotating and scaling depend on a reference point to perform the relevant action, this point is called a pivot point. Using pivot point may seem easy if you have worked with 2D software like After Effects or Photoshop. But with Blender, it is a bit more difficult.

So let’s learn everything you need to know about pivot point in Blender in 2025, what they are, and how they work. Let’s get started!

What is Pivot Point in Blender?

In Blender, a pivot point is a point around which objects are rotated, scaled, or translated. It acts as a reference point for transformations, and you can change its position to affect how objects are manipulated. For example, we can rotate selected parts of a mesh around a point in edit mode, or scale an object, or divide the distance between objects relative to the pivot point. By default, the pivot point is the origin of the selected object or the midpoint between multiple origins of the selected object. It is the small orange dot placed at the center of the object. But we can use many other points as pivot point to transform around.

To change the pivot point in the Blender viewport, go to the 3D Viewpoint header and find the transform pivot point menu between the transform orientation options and the snapping options. Click on it and select the element you want to set as the pivot point. And there are no additional settings to set a pivot point; after all, it’s just a point in space. We just need to set which point is the active pivot point for our object and work on it.

Overview of Pivot Point Types

As you can see, there are 5 types of pivot point. Let’s find out what they are specifically and how they work.

Bounding Box Center

Each object has a bounding box around it. The geometry location determines its size and will be the exact size needed to fit all the mesh inside. With this setting, the pivot point is at the center of the bounding box.

In object mode, the pivot point becomes the center of the bounding box around the selected object’s origin points, not their geometry. This means that if you select a single object, the pivot point will be the same as the object’s origin point, which can be customized and not necessarily at the center. But if you select multiple objects, the pivot point becomes the center of an imaginary box around their origin points. In edit mode, the pivot point becomes the center of the bounding box around the selected mesh elements. However, the median point may give a different result. View the bounding box by going to the 3D Viewpoint Header > Pivot Point > Bounding Box Center. For mesh objects, it’s the yellow box icon.

3D Cursor

The 3D Cursor is a point in space that has both position and rotation, and can be used as a pivot point. This is a flexible pivot point because we can quickly move the 3D Cursor around precisely. For example, we can quickly move it to our current selection by pressing Shift+S and choosing “Cursor to selected item”. In the 3D Viewpoint, it is a circle with alternating white and red stripes. View the 3D Cursor by going to 3D Viewpoint Header > Pivot Point > 3D Cursor.

Individual Origins

Individual origins is a special mode because it uses the origin of each individual selected object or selected mesh. If we select multiple objects and double-tap R to rotate the trackball, we will know how this mode works. And each object rotates individually around its own origin instead of rotating all the objects around a single point. So it is very useful when performing batch operations.

In object mode, each object is transformed around its origin. This is a freely selected point and does not have to be in the middle. In edit mode, each selected element is transformed around its own center point. Furthermore, when you transform adjacent faces or edges, they are not disconnected and act as a single element. Go to this mode by heading to 3D Viewpoint > Pivot Point > Individual Origins.

Median Point

The median point is the average position of the selected items. This is the default option. This is different from the bounding box, which just takes the center of everything selected without any weight and uses it as the pivot point. In object mode, the median point is the average position of the origin of the selected objects. With the shape and size of the object not taken into account. The origin can be freely selected and is outside the object geometry. So the median point is not always what you want. In edit mode, the median point is the average position of the selected vertices. This means that the pivot point will shift towards the densest geometry, as they have a higher ‘weight’. View this mode by selecting 3D Viewpoint Header > Pivot Point > Median Point.

Active Element

The active element is the last selected element. For example, if you select multiple objects in a row by holding Shift, you will see that the last selected object has a lighter outline, that is the active element. This will be the point used as the pivot point. In object mode, rotation and scaling take place around the origin of the active element. In edit mode, the pivot point will be the median point of the last selected element. In vertex selection mode, this is the last selected vertex. However, for edges, this is the edge’s location. And for faces, this is the median point of the vertices connected to the face. It is suitable for precise control, especially in edit mode when working with vertices or faces. See this mode by going to 3D Viewpoint Header > Pivot Point > Active Element.

How to Change the Pivot Point?

There are many ways to change the pivot point depending on your purpose. You can refer to the 3 ways below.

Manual Way

The pivot can be manually adjusted, so it won’t automatically line up with your model or anything in the scene. Most of the time, but not always, this solution will work. This is how you go about it:

  • Choose the item whose pivot point needs to be altered.
  • Press the TAB to enter edit mode.
  • Move (G) the selected object to your desired location after selecting all vertices (A).
  • Now that you have altered the object’s pivot, exit edit mode (TAB).

Using an Empty

Although it is not a permanent alteration, there is an additional method for manually altering an object’s pivot in Blender. You can make the empty act as the pivot point by creating an empty and parenting it to your chosen object. If you are working with a heavy model and are unable to enter edit mode without it slowing, this can be helpful.

  • To access Plain Axes (or any other option; it’s merely a visual representation), press Shift + A.
  • Move the Empty to the pivot point location of your choice after selecting it.
  • Shift-click the Empty after clicking on the object.
  • To choose Object (Keep Transform), press CTRL + P.
  • You can now use the Empty to rotate the object.

Using 3D Cursor

The 3D cursor can also be used as a global pivot point; however, keep in mind that everything that uses it as a pivot will also revolve around it. Therefore, if there are several items dispersed around the scene, they will all revolve around the same point.

Using the 3D cursor as a global pivot point

  • Press the icon that resembles two chain links in the middle top toolbar (apart from the dropdown menu that says “Global”).
  • Choose 3D Cursor from the option that drops down.
  • To adjust the 3D cursor’s position, shift + right-click anywhere in the scene.
  • To position the 3D cursor at the chosen point, you can alternatively enter edit mode, pick a vertex, edge, or face, press SHIFT + S, and choose “Cursor to selected.”
  • Now, everything will revolve around the 3D pointer.

Pivot Point in Blender All You Need to Know 5

Using the 3D cursor to assign a new pivot point for an object

However, what if you wish to alter the pivot to an object’s vertex permanently?  Actually, it’s not all that different from the previously mentioned steps.  Just make sure that the 3D cursor in the upper middle menu has been replaced with the pivot point set back to Median Point.

  •  After choosing your object, select Edit Mode (TAB).
  •  Choose a face, edge, or vertex.
  •  To exit edit mode (TAB), use SHIFT + S > Cursor to Selected.
  •  Locate “Object” in the menu on the upper left. Object >  Configure Origin >  Origin of the 3D cursor
  •  Hit SHIFT + S >  To return the 3D pointer to the center, move it to the World Origin.

Advantages and Disadvantages of CPU and GPU Rendering in Blender

When it comes to rendering in Blender, one of the necessary decisions you’ll face is whether to use your CPU (Central Processing Unit) or GPU (Graphics Processing Unit). Both options offer distinct advantages and disadvantages, making the choice important for optimizing rendering times and overall efficiency. This blog dives deep into the pros and cons of CPU and GPU rendering, providing you with a comprehensive understanding to make an informed decision tailored to your specific project needs and hardware capabilities. By exploring these aspects, you can explore the full potential of Blender and streamline your rendering workflow. 

Let’s get started!

Advantages and Disadvantages of CPU Rendering in Blender

Advantages

CPU (Central Processing Unit) rendering in Blender involves utilizing the computer’s main processor to generate the final image. While GPU (Graphics Processing Unit) rendering has gained prominence due to its speed advantages, CPU rendering remains a viable and, in some cases, preferable option. CPUs are renowned for their precision in calculations, ensuring highly accurate and reliable results. This accuracy is particularly beneficial when dealing with scenes that require precise lighting, shadows, and reflections. Moreover, CPUs can effectively manage scenes with high polygon counts, advanced effects, and intricate simulations due to their robust processing capabilities. They are less prone to running into memory limitations when handling extremely large and detailed scenes. Additionally, one more thing is that CPU rendering is generally more compatible with a wider range of Blender features, plugins, and rendering engines. It ensures consistent performance across different hardware configurations and software versions.

Disadvantages

Despite its advantages, CPU rendering also has notable drawbacks that should be considered. CPUs are generally slower at rendering images compared to GPUs due to their sequential processing nature. This can significantly increase the time required to complete rendering projects, especially for animations and high-resolution images. CPUs are not specifically designed for visual data processing, making them less efficient for rendering-intensive tasks. They lack the specialized hardware and parallel processing capabilities of GPUs, resulting in slower performance. Rendering on the CPU can consume a significant amount of system resources, potentially impacting the performance of other applications running simultaneously. Also, CPUs are not well-suited for real-time rendering applications, such as game development and interactive visualizations. Their slower processing speeds and lack of specialized hardware make it difficult to achieve the required frame rates for smooth real-time performance.

Advantages and Disadvantages of GPU Rendering in Blender

Advantages

GPUs can significantly reduce rendering times compared to CPUs due to their parallel processing capabilities. This speed advantage is particularly noticeable when rendering complex scenes with high polygon counts and advanced effects. Designed specifically for graphics and image processing, GPUs are highly efficient at handling the calculations required for rendering. They excel at tasks such as ray tracing, shading, and texture mapping, resulting in faster and more efficient rendering performance.

The specific GPU model used has a significant impact on rendering speed and efficiency. Higher-end GPUs with more CUDA or OpenCL cores and larger VRAM capacities generally deliver better performance in Blender.

As Blender can use multiple GPUs for rendering, it can increase speed and reduce rendering time. You can add more GPUs to increase rendering power which allows for faster completion of complex projects. Distributes the rendering workload, preventing any single GPU from being overloaded.

Disadvantages

GPUs have limited video memory (VRAM), which can be a bottleneck when rendering extremely complex scenes with high-resolution textures. If the scene exceeds the available VRAM, Blender may resort to using system memory, which can significantly slow down the rendering process. Besides, GPU performance is heavily dependent on having the latest and most stable drivers. Therefore, outdated or incompatible drivers can cause crashes, errors, or reduced performance.

Key Factors to Consider

Several factors should be considered when choosing between CPU and GPU rendering in Blender:

  • Scene Complexity: Assess the complexity of your scene. For scenes with intricate details, high polygon counts, and advanced effects, a CPU might be more reliable due to its accuracy and memory handling. In contrast, simpler scenes can benefit from the speed of GPU rendering.
  • Hardware Specifications: Evaluate the specifications of your CPU and GPU. A high-end GPU with a large amount of VRAM will likely outperform a mid-range CPU in rendering tasks. Conversely, a powerful CPU with sufficient RAM can handle complex scenes that might overwhelm a lower-end GPU.
  • Rendering Engine: Different rendering engines in Blender, such as Cycles and Eevee, utilize hardware resources differently. Cycles tends to benefit more from GPU rendering due to its path-tracing algorithm, while Eevee is a real-time engine that can utilize both CPU and GPU.
  • Project Requirements: Consider the specific requirements of your project. For animations or tasks where speed is critical, GPU rendering can significantly reduce production time. For architectural visualizations or product renderings where accuracy is paramount, CPU rendering might be the preferred choice.
  • Budget: Take your budget into account. High-end GPUs can be a significant investment, while upgrading a CPU might be a more cost-effective solution depending on your existing hardware.

Benchmarking and Testing

Currently, the overall fastest CPU for Blender depends on your specific workflow. Modeling and animation tasks are better on a single, fast core. While rendering is better with large numbers of cores. Simulations are somewhat split. Cloth and rigid body simulations only use a few fast cores, while fluid simulations will use lots of cores.

If you will be doing a lot of fluid simulations, or relying on CPU rendering, then the current fastest CPU is AMD’s Threadripper™ 7995WX. It offers 96-cores, and support for up to a massive 1TB of RAM.

If you are primarily interested in modeling and animation, the AMD RyzenTM 9000 Series and Intel CoreTM Ultra CPUs are the ideal choices. Higher core count models like the Ultra 9 285K and Ryzen 9 9950X will provide superior CPU-based rendering if necessary, while lower core count models like the Core Ultra 7 265K and Ryzen 7 9700X are more reasonably priced.

Hybrid Rendering

In some cases, the ideal solution is to use both the CPU and GPU simultaneously through hybrid rendering. Blender allows you to configure Cycles to utilize both your CPU and GPU, distributing the rendering workload and potentially achieving faster rendering times than either processor could manage on its own. By utilizing both the CPU and GPU, Blender can distribute the rendering workload and potentially reduce rendering times compared to using only one processor. Hybrid rendering allows Blender to take advantage of all available computing resources, maximizing efficiency. When dealing with scenes that have both high complexity and high polygon counts, the CPU can handle the complex calculations while the GPU accelerates the rendering of visual elements.

How to Enable Hybrid CPU and GPU Rendering in Blender:

  • Open Blender’s Preferences: Go to Edit > Preferences. 
  • Access System Settings: Navigate to the System tab. 
  • Select Render Devices: Under “Cycles Render Devices,” you will see options for your CPU (typically named “CPU”) and GPU (e.g., “CUDA”, “OptiX”, “HIP”, “oneAPI”, “Metal”). 
  • Enable Both: Check the boxes next to both your CPU and GPU to enable them for rendering. 

Is CPU or GPU better for rendering in Blender?

There’s no definitive “better” option between CPU and GPU rendering in Blender. The ideal choice depends on your specific circumstances. CPU rendering offers accuracy, stability, and the ability to handle extremely complex scenes that might exceed GPU memory.

GPU rendering is generally faster for most tasks due to its parallel processing capabilities. It’s especially efficient for visually intensive tasks. In many cases, using multi GPUs can work in parallel, reducing the time it takes to render images or animations. This is particularly beneficial for complex scenes where every second counts. With multiple GPUs, Blender can improve viewport rendering performance, facilitating smoother interactions and real-time updates even in complex scenes. This allows for more efficient modeling and scene composition. Therefore, if you want to improve your render’s performance, you can consider GPU rendering.

Conclusion

In conclusion, both CPU and GPU rendering have their respective advantages and disadvantages, and the optimal choice depends on the specific demands of your project and workflow. For many users, a hybrid approach that utilizes both CPU and GPU rendering can provide the best of both worlds, depending on the scene complexity and rendering requirements. Ultimately, understanding your hardware capabilities and the nature of your projects will guide your decision in choosing the most effective rendering method in Blender.

Top Reasons Your Blender Render Is Black and How to Fix Them

A black or completely blank render in Blender can be frustrating, especially when your viewport looks fine. Fortunately, the problem is usually easy to diagnose and fix. Here’s a comprehensive guide to help you determine why Blender is rendering black and how to resolve the issue quickly. Let’s explore in this blog with iRender!

Top Reasons Your Blender Render Is Black and How to Fix Them 1

1. Surfaces is not enabled

If the grey screen doesn’t change and the render remains blank, it might be because Surfaces are disabled. Without surfaces, Cycles has no geometry to render. 

✅ Tips to Fix:

Go to Properties > View Layer Properties > Filter, and make sure the Surface option is checked.

Top Reasons Your Blender Render Is Black and How to Fix Them 2

2. No Active Camera or Camera Is Misplaced

Blender renders only from an active camera. If none is set, or it’s pointing at space, you’ll get a black screen.

Top Reasons Your Blender Render Is Black and How to Fix Them 3

✅ Tips to Fix:

  • Press the Numpad 0 key to view the active camera.
  • If the camera isn’t aligned properly, select it and press Ctrl + Alt + Numpad 0 to snap it to your current view.
  • Check the Camera Clipping Range in the Camera Properties—make sure it’s not clipping out your scene.
Top Reasons Your Blender Render Is Black and How to Fix Them 4

3. Objects Are Hidden or Not Renderable

Sometimes objects are visible in the viewport but are disabled from rendering.

✅ Tips to Fix:

  • Open the Outliner and make sure the Camera icon is enabled for all relevant objects.
  • Check for objects inside disabled collections.

Make sure the object’s Scale isn’t zero or that it hasn’t been moved far from the camera view.

Top Reasons Your Blender Render Is Black and How to Fix Them 5

4. Compositor Node Errors

Sometimes, you’ll see the image appear while rendering, but it disappears once the render finishes. This issue is often related to problems in the Compositor.

  • Disconnected Composite Node: Make sure the Composite node is connected—this is the final output for rendering (not the Viewer node).
  • Incorrect Node Setup: The compositing nodes may be causing unwanted effects. Try disabling, bypassing, or disconnecting nodes to isolate the problem.
  • Wrong View Layer or Pass: Double-check that the Render Layers node is referencing the correct layer. Also, ensure you’re using the proper color socket—not alpha, depth, or another pass.
  • Using Output from Another Scene: Confirm that the View Layer node is set to the current scene in the dropdown menu, not a different one.
  • Glare Node Overpowering the Image: If you’re using a Glare node, keep an eye on the Mix Factor. A high value can cause the glare to completely obscure the original image. The default value is 0—stick close to that unless you want heavy glow effects.
Top Reasons Your Blender Render Is Black and How to Fix Them 6

5. The clip distance for the camera is set incorrectly

Ensure the camera’s clip start and end values are set to include the full range of your scene. Any geometry positioned outside this distance—either too close or too far—won’t be visible in the final render.

Top Reasons Your Blender Render Is Black and How to Fix Them 7

If your scene is extremely large or very small, and it falls outside the camera’s clipping range, the camera won’t be able to “see” it. To help visualize this, enable Display Limits in the camera settings to see the clipping boundaries directly in the viewport.

Top Reasons Your Blender Render Is Black and How to Fix Them 8

Conclusion

Blank or black renders in Blender can be caused by a variety of issues, including a missing camera or lighting setup, incorrect compositor nodes, or incorrect clipping distances. By checking each element step-by-step—from visibility settings to render layers—you can quickly identify and resolve the issue.

For complex projects or high-resolution scenes that demand more GPU power, consider rendering with iRender. With powerful cloud-based GPU servers optimized for Blender (including Cycles and Eevee), iRender ensures your projects render faster and more reliably, without the headache of local hardware limitations.

Blender Cycles Optimization Tips for Low-end PC (2025)

Blender’s Cycles produces stunningly realistic renders, but that realism comes at a cost. Running it on a low-end PC can feel like trying to run a marathon in flip-flops. Laggy viewports, crashes, and endless render times are common struggles, but there’s hope. With the right settings and workflow adjustments, Blender Cycles runs surprisingly well, even on outdated or budget hardware. This guide’ll walk through practical Blender Cycles optimization tips tailored for low-end PCs in 2025. An artist just got his render time from 50 minutes to 40 seconds per frame on his 8-year-old GTX 1050, and here’s how he did it. Let’s learn more about them!

Enable Persistent Data

When rendering animations in Blender using Cycles, you may notice a short pause at the beginning of each frame, where textures and other assets appear to reload before the actual rendering begins. This pre-processing stage can take several seconds, especially in complex scenes, which happen repeatedly for each frame.

This is where Persistent Data comes in. When enabled, Blender keeps certain data, such as textures, geometry, and shaders, in memory across multiple frames. This means that Blender doesn’t have to reload everything from scratch each time, which can significantly speed up render times, especially for animations.

While the benefits may be less noticeable on slower machines due to hardware bottlenecks, enabling Persistent Data can make a significant difference on more capable systems or even modest setups when rendering multiple frames.

Blender Cycles Optimization Tips for a Low-end PC 1

To enable, go to Render Properties > Performance > Persistent Data.

Adjust Light Bounces

When you start exploring Cycles, one of the first performance-related settings you’ll come across is Light Bounces. These settings control how many times a light ray can bounce off a surface before Blender stops calculating. By default, Blender sets it at 12 bounces to ensure physically accurate lighting and realistic results.

Of course, you might think that reducing the number of bounces would result in faster rendering, and you’d be right. But here’s the thing: when we tried reducing the maximum number of bounces, the scene rendered much faster, but the overall lighting looked unnaturally flat and dark. It’s a clear trade-off between speed and image quality.

Therefore, in scenes where indirect and reflected light play a large role, such as interiors or reflective materials, reducing the number of light bounces can significantly degrade the final image. However, in simpler setups or scenes where the light is more direct, reducing Light Bounces can be an effective way to shorten render times without sacrificing too much quality.

Blender Cycles Optimization Tips for a Low-end PC 2

To adjust, go to Render Properties > Light Paths and experiment with reducing values ​​such as Max Bounces, Diffuse, and Glossy bounces to see how it affects both render times and image fidelity.

Optimizing Tile Size

One of the most frustrating issues many Blender artists encounter when rendering with Cycles is the dreaded ‘Out of GPU Memory’ error. This error pops up frequently, especially in complex scenes, interrupting the render process and slowing down my workflow. At first, you can close background applications to free up resources.

However, what makes a noticeable difference is adjusting the Tile Size, a setting that controls how much of the image Cycles renders at a time. Initially, the tile size is set to 148, meaning the GPU has to process large chunks of the image in each run. This puts a lot of pressure on the limited VRAM, causing it to crash frequently.

After increasing the tile size to 512, the system performs best with older GPUs with 4GB of VRAM. By rendering each tile larger, the GPU can process each block more efficiently without running out of memory. As a result, not only will the memory errors stop, but the render time will also decrease by about 10%.

Blender Cycles Optimization Tips for a Low-end PC 3

To adjust this setting, go to Render Properties > Performance > Tiles and experiment with different tile sizes. 

Note: For GPU rendering, larger tiles (e.g., 256 or 512) generally work better, while smaller tiles are more efficient for CPU rendering.

Adjust the Pixel Size

If you’ve ever rendered a complex 3D scene in Blender and noticed that the final image looks a little blurry or lacks sharp detail, the Pixel Size setting may be the problem. By default, this value is usually set to 1.5 pixels.

Try reducing the pixel size to 1.0. This forces Blender to calculate each pixel more accurately, resulting in sharper edges, clearer textures, and a more polished overall render. That little tweak brought back the clarity and detail with just one simple adjustment. 

Blender Cycles Optimization Tips for a Low-end PC 4

You can find this setting in the Render Properties under the Sampling or Output section, depending on your version of Blender.

Turn off Light Tree

If your render times are still unusually long, even after tweaking your general settings, there’s one more feature worth checking out: Light Tree. Introduced in Blender 3.5, this option is designed to optimize lighting by managing multiple light sources more intelligently. However, in practice, especially for scenes with many lights, this option often adds unnecessary overhead without significantly improving image quality.

You can turn off Light Tree, many users have reported significant performance gains. In one case, disabling it reduced render times from 8 minutes to just 2 minutes per frame without any noticeable loss in quality. If you are working on a low-end PC and your scene does not rely on complex lighting behavior, you should turn it off.

Blender Cycles Optimization Tips for a Low-end PC 5

You’ll find this setting under Render Properties > Sampling > Light Paths. By default, it’s enabled.

Using Samples, Noise Thresholds, and Denoising

In Blender, samples determine how many light rays are calculated per pixel. While higher sample counts can improve image quality, they also result in significantly longer render times.

To optimize performance, try working with a lower sample count, ideally between 50 and 100. But instead of manually adjusting it for each scene, you can use the Noise Threshold setting to handle sampling smarter. This feature adjusts the number of samples per pixel based on the noise level in specific areas of the image. For example, darker or more complex areas will receive more samples, while simpler areas will receive fewer samples.

By default, the Noise Threshold is set to 0.01. Reducing the threshold to 0.1 or even 0.5 can significantly reduce render times with minimal impact on image quality. A threshold of 0.5 is usually the sweet spot for low-end PCs.

The final piece is denoising. This feature uses algorithms to clean up noisy renders, allowing you to work with fewer samples, sometimes as few as 30, while still achieving clean, professional results. In many cases, a denoised render with 30 samples will look better than an undenoised render with hundreds of samples.

Blender Cycles Optimization Tips for a Low-end PC 6

To summarize:

  • Set the sample count to a low base (around 50)
  • Adjust the noise threshold to 0.5 or 0.1
  • Enable denoising in both the viewport and the final render

These small tweaks can easily cut your render times by 2-5x without sacrificing image quality.

4K Resolution

The most impactful change for Blender Cycles optimization is that you can improve the detail and quality of your renders by increasing the resolution, especially when moving from HD to 4K (Ultra HD). This upgrade gives you four times more pixels, which means much sharper details and a more vibrant overall image.

While higher resolution will increase render times, it is often more cost-effective than increasing the number of samples. Even 30 samples in 4K with denoising can look better than 100 samples in HD. Plus, denoising works more accurately at higher resolutions, removing noise with better accuracy.

If your image doesn’t have enough detail, simply increase the resolution. This is the simplest and most effective way to increase quality.

Frame Interpolation

If you’ve already optimized your render settings, here’s an even more powerful trick to speed up animation rendering: use AI frame interpolation.

Say your animation has 300 frames at 30fps; that’s a lot to render. But you can cut that time in half simply by rendering frame by frame. Then, instead of sacrificing smooth motion, use an AI tool like Flowframes.

Flowframes analyzes the motion between frames and automatically fills in the missing frames using deep learning. And you’ll get smooth, natural-looking animation that looks as if you’d rendered every frame in a fraction of the time.

Choosing the Right Hardware (GPU vs CPU)

One of the most effective ways to speed up your rendering in Blender is to use the right hardware settings. In Render Properties, you can choose to render using the CPU, GPU, or both. While it may seem logical to have both enabled, the reality is that using only the GPU is often significantly faster, especially for Cycles.

To apply this, simply go to Edit > Preferences > System and make sure your GPU (CUDA, OptiX, or HIP, depending on your hardware) is selected. In Render Properties, change the Device to GPU Compute instead of CPU. This small change can significantly reduce render times, especially on machines with dedicated graphics cards.

Blender Cycles Optimization Tips for a Low-end PC 9

Use Older Blender Version

Another way of Blender Cycles optimization that may annoy some people, but it’s the most important when trying to get Blender to run smoothly on a low-end PC. If your device doesn’t meet the minimum requirements for the latest Blender version, the best solution is often to install an older Blender version. All previous versions of Blender are available on the official website. Once you’re on the site, click on Download, then select Previous Versions, and you’ll see a full list of releases.

It’s recommended to try Blender 2.8 first before going further back, so you can still take advantage of many newer features while improving performance.

Nvidia and AMD: Which option is better for rendering in Blender?

As we know that Blender is a leading software choice for artists and developers worldwide. Its powerful rendering capabilities play a critical role in bringing creative visions to life, and at the heart of these rendering processes sits the graphics processing unit (GPU). When discussing GPUs to use for Blender rendering,  Nvidia and AMD are the two names that most frequently come up. Each brand offers unique advantages and technologies that cater to different rendering needs. 

In this blog, , iRender will make a comprehensive comparison of Nvidia and AMD GPUs, exploring their performance, features, and overall value in the context of Blender rendering.

What are Nvidia and AMD GPUs?

Nvidia graphics cards are among the top GPU (Graphics Processing Unit) technology these days. The Nvidia corporation specializes in high-performance graphics processing hardware and software, ranging from graphics cards to graphics drivers and graphics optimization utilities. Nvidia graphics cards are high-performance devices that enable powerful graphics rendering and processing for use in video editing, video gaming, and other complex computing operations. Nvidia GeForce RTX 4090/RTX 5090 are the latest and most powerful cards and a sought-after model currently on the market. 

AMD GPUs (Advanced Micro Devices Graphics Processing Units) are a line of graphics cards designed for gaming, professional rendering, and computing applications. AMD GPUs are known for delivering a balance of performance and cost-effectiveness, making them popular among gamers, content creators, and professionals alike. The Radeon series is the primary branding for AMD’s graphics products, which use advanced architectures to achieve high-quality graphics and efficient processing. The Radeon RX 6800 XT and Radeon RX 7900 XTX are prime examples, showcasing the power and versatility of AMD’s graphics technology.

Performance

When comparing the performance of Nvidia and AMD GPUs for rendering in Blender, it’s essential to consider factors such as rendering speed, ray tracing capabilities, and overall efficiency when handling complex scenes. Blender utilizes different rendering engines such as Cycles (ray-traced) and Eevee (real-time). Performance can vary significantly based on the engine used. Because Nvidia GPUs typically utilize CUDA for rendering, which often results in faster performance in Cycles. Meanwhile, AMD GPUs use OpenCL for computation in rendering tasks, which has improved but may not efficient as Nvidia’s CUDA.

Nvidia has an edge with its RTX series due to dedicated hardware for ray tracing (RT cores), allowing for superior performance in ray-traced workloads. AMD‘s recent GPUs, such as those based on the RDNA 2 architecture, also support ray tracing but may offer lower performance in this area compared to Nvidia.

To understand more detailed, I will take an example to compare the performance of two most powerful graphics cards of both Nvidia and AMD cards: Nvidia GeForce RTX 4090 and AMD Radeon RX 7900 XTX.

Feature Nvidia GeForce RTX 4090 AMD Radeon RX 7900 XTX. 
CUDA Cores 16,384 CUDA cores  6,144 CUDA cores
VRAM 24 GB GDDR6X VRAM  24 GB GDDR6 memory
Total Graphics Power (TGP 450 watts 355 watts
Memory bandwidth 1008 GB/s 960 GB/s
Clock Speed 2.23 – 2.52 GHz 1.9-2.3 GHz

The most notable difference between the two GPUs is the number of CUDA cores, which are essential for parallel processing. The Nvidia RTX 4090 boasts an impressive 16,384 CUDA cores, while the AMD RX 7900 XTX includes 6,144 CUDA cores. CUDA cores are unique to Nvidia’s architecture, but they provide a useful metric for comparing raw computational power. In contrast, the RX 7900 XTX may offer strong performance but does not match the sheer parallel power of Nvidia’s offering.

Secondly, both graphics cards come with 24 GB of VRAM, which is more than sufficient for modern 4K gaming and professional applications. However, the RTX 4090 uses GDDR6X memory, whereas the RX 7900 XTX uses standard GDDR6. GDDR6X is faster and offers higher bandwidth, allowing quicker access to stored data.

Moreover, the RTX 4090 consumes up to 450 watts, while the RX 7900 XTX is more power-efficient at 355 watts. Another key performance is memory bandwidth, which affects how quickly data can be transferred to and from the GPU’s memory. The RTX 4090 again leads with 1008 GB/s, compared to 960 GB/s on the RX 7900 XTX. Although both figures are quite high, the extra bandwidth provided by the RTX 4090 ensures smoother performance with 5% faster compared to RX 7900 XTX.

Clock speed measures how fast the GPU core operates. The RTX 4090 offers a clock speed range of 2.23 to 2.52 GHz, while the RX 7900 XTX ranges from 1.9 to 2.3 GHz. This means that the performance of Nvidia RTX 4090 is still higher than RX 7900 XTX.

In general, Nvidia RTX 4090 outperforms the AMD RX 7900 XTX. It is designed for users who demand the highest levels of performance, whether for ultra-high-resolution gaming, AI development, or professional rendering tasks. Meanwhile, the AMD Radeon RX 7900 XTX remains a strong competitor. It offers high-end performance with slightly lower power consumption and similar VRAM capacity, making it a more cost-effective and energy-efficient solution for gamers and creators.

Performance Testing

When evaluating GPU performance in Blender, focus on benchmarks that reflect your specific workload. You can check the Blender benchmark to compare the performance of NVIDIA and AMD for Blender rendering.

Nvidia and AMD: Which option is better for rendering in Blender? 2
Image source: Tom's Hardware

At the top of the performance chart stands NVIDIA’s RTX 4090, with an astonishing benchmark score of 6,977.7. This result is significantly higher than any other GPU, which is the best option for Blender rendering.

Secondly, The RTX 4080, scoring 5,065.9, trails behind but still demonstrates impressive capability. It offers around 72% of the RTX 4090’s performance, making it a more affordable yet highly competent option for professional users. Nextly, the RTX 3090 Ti and RTX 4070 rank third and fourth, scoring 3,273.6 and 3,113.3, respectively. While the 3090 Ti is from the previous generation (Ampere), it still outpaces the newer 4070, although the 4070 brings better power efficiency and pricing. All in all, NVIDIA GPUs consistently deliver superior performance in Blender rendering tasks, particularly in the high-end segment. 

Besides, AMD’s latest generation of 3 GPUs, including the RX 7900 XTX, 7900 XT, and 7800 XT, occupy the mid-tier of the chart. The RX 7900 XTX leads the AMD lineup with a benchmark score of 1,874.0, followed closely by the 7900 XT at 1,837.0. These results are competitive, especially considering their price points relative to NVIDIA’s higher-end cards. However, AMD GPUs are still lagging behind NVIDIA in rendering workloads, largely due to less efficient support for rendering APIs such as OptiX, which NVIDIA uses to great effect. 

Additionally, you can check the blender testing Classroom, Junkshop scene to see the performance:

Nvidia and AMD: Which option is better for rendering in Blender?
Image source: Tom's Hardware
Nvidia and AMD: Which option is better for rendering in Blender? 4
Image siurce: tomshardware

Across both benchmark above, NVIDIA consistently dominates the upper tier of performance. The RTX 4090, RTX 4080, RTX 3090 Ti, and RTX 4070 hold the top four positions in both the Junkshop and Classroom charts. For example, in the Blender Junkshop scene, the RTX 4090 scores a massive 2840.5, and in the Classroom scene, it performs even better at 2951.5. The RTX 4080 follows with scores of 2142.0 and 2239.9 respectively. These scores are significantly higher than any AMD offering.

On the other hand, AMD GPUs such as the RX 7900 XTX and RX 7900 XT fall significantly behind their NVIDIA counterparts in both benchmark scenes.

In summary, the testing results from both Blender Junkshop and Classroom benchmarks strongly favors NVIDIA GPUs for Blender rendering tasks. With far superior performance, better software optimization, and robust support for rendering technologies like CUDA and OptiX, NVIDIA clearly offers the best value for creators and professionals working in Blender.

Driver support and Software stability

NVIDIA

Nvidia is known for regularly updating its drivers, which often include optimizations for the latest software, games, and rendering engines. NVIDIA drivers tend to include specific optimizations for popular creative applications, including Blender. This can lead to improved performance and stability during rendering tasks. With NVIDIA Studio Drivers, users can access drivers specifically designed for creative applications, ensuring stability and performance with software like Blender. These drivers are tailored for the demands of artists and designers.

Besides, NVIDIA has a strong reputation for driver stability, particularly in professional environments. Users often report fewer crashes and issues when working with Blender, especially while rendering. The extensive support for CUDA and OptiX contributes to stable performance in rendering tasks. Users have access to a robust ecosystem of tools and features that facilitate efficient workflows. Generally, user feedback regarding NVIDIA’s drivers is positive, suggesting that issues are relatively rare compared to other manufacturers.

AMD

AMD releases driver updates regularly, but their cadence can sometimes be less frequent than NVIDIA’s, particularly for creative applications. Drivers are optimized for OpenCL, which is used in Blender’s Cycles rendering. However, performance can vary and may not always match NVIDIA’s optimizations for CUDA. While AMD has made significant strides in supporting creative applications, historically, there have been more instances of compatibility issues or performance inconsistencies compared to NVIDIA.

Price and Availability

Nvidia’s GPUs are highly sought after for Blender rendering due to their CUDA support, which accelerates performance in the Cycles rendering engine, as well as advanced features like RTX ray tracing and DLSS. However, their premium performance often comes at a higher price point, and availability can be a concern.

Pricing

Generally, NVIDIA GPUs are considered better for Blender rendering, especially when using the Cycles render engine. However, the price and availability of both NVIDIA and AMD GPUs can vary. NVIDIA GPUs tend to be more expensive than AMD GPUs. For instance, to match the performance of an AMD 7900 XTX, you would need an NVIDIA Titan RTX, and even then, the NVIDIA card might outperform it

Availability

Nvidia’s GPUs is generally available at major retailers (Amazon, Newegg, Best Buy), but stock levels can be inconsistent. You should keep an eye out for restocks and be prepared to act quickly when you find it at a reasonable price. The used market can be an option, but exercise caution and verify the card’s condition before purchasing.

Conclusion

In conclusion, while AMD GPUs present a budget-friendly option with potentially larger VRAM, NVIDIA GPUs generally offer superior rendering performance in Blender due to their optimized CUDA and OptiX APIs. For users prioritizing speed and efficiency in rendering, NVIDIA is the preferred choice. However, AMD remains a viable alternative, especially for those with budgetary constraints or specific needs for larger VRAM. The best option ultimately depends on individual priorities and workflow requirements.

Multiple graphics cards can help shorten rendering time, but what if multi-GPU rendering isn’t utilizing all your GPU cards? Scroll down to find out!

Multi-GPU rendering

GPU rendering refers to the use of a graphics processing unit’s capabilities to render scenes or animations. It takes advantage of the GPU’s parallel processing power, VRAM, and limited CPU assistance to deliver much faster performance compared to CPU-only rendering. You can learn more about the advantages and disadvantages of GPU rendering in this article.

Multi-GPU rendering involves using two or more GPUs (graphics cards) at the same time for rendering tasks. This technique distributes the workload across all GPUs, greatly improving rendering speed, especially when working with complex 3D environments. Due to its performance benefits, many rendering engines are designed to support multi-GPU rendering. Well-known engines that utilize this approach include Redshift, Octane Render, Blender Cycles, and V-Ray.

Common Multi-GPU Rendering Issue

Multi-GPU rendering doesn’t use all GPU cards - How to check and fix 1

One of the most common issues iRender helps users solve is when the render engine fails to utilize all available GPU cards during multi-GPU rendering. The first step in troubleshooting this problem is checking GPU usage. While Task Manager is a typical tool for monitoring hardware, in our experience, its readings can sometimes be inaccurate. Therefore, we always verify performance with additional tools. We recommend using MSI Afterburner, Nvidia-SMI, or GPU-Z as more reliable alternatives.

MSI Afterburner

MSI Afterburner is a widely used tool for overclocking graphics cards, allowing users to tweak and monitor various GPU settings. Although it’s developed by MSI, the software works with most GPU brands like NVIDIA, AMD.

In addition to overclocking, it enables users to keep track of critical stats like CPU and GPU temperature, frame rate (FPS), memory usage, and fan speeds—all of which help ensure better performance and system stability. 

You can enable the on-screen display (OSD) to get live hardware performance updates while rendering, or open the app and navigate to the GPU Usage section to view how each graphics card is performing during multi-GPU rendering.

GPU-Z

GPU-Z, developed by TechPowerUp, is a compact and powerful tool that gives in-depth information about your GPU. Its core purpose is to show details such as the graphics card’s model, brand, memory type, and much more. On top of that, it provides real-time monitoring of GPU performance metrics like temperature, usage levels, memory load, and clock speeds—helpful for assessing both efficiency and thermal output.

It’s compatible with a wide array of GPUs, including models from NVIDIA, AMD, ATI, and Intel, and works on most Windows systems. A notable perk is that GPU-Z can be run without installation, making it extremely convenient. 

For users working with multi-GPU rendering, GPU-Z is especially valuable, as it allows real-time tracking of each GPU’s performance, useful for diagnosing issues or identifying which cards are delivering the best results.

Nvidia-SMI

Multi-GPU rendering doesn’t use all GPU cards - How to check and fix 3

Nvidia-SMI (short for NVIDIA System Management Interface) is a command-line utility provided by NVIDIA, designed for monitoring and controlling NVIDIA GPU hardware.

It offers comprehensive system information, including GPU count, model names, memory allocations, and usage stats. One of its key strengths is the ability to observe real-time GPU data—like temperature, power draw, memory consumption, and clock speeds—which is critical for avoiding performance drops due to overheating during demanding rendering tasks.

This tool is especially helpful when diagnosing multi-GPU rendering issues. If performance isn’t as expected, you can use Nvidia-SMI to check whether GPUs are being properly utilized or if there’s a thermal or memory bottleneck affecting the system. 

Additionally, it lets users tweak settings such as power limits and fan control, giving more flexibility in optimizing the GPU environment for rendering workloads.

Workarounds When Multi-GPU Rendering Doesn’t Utilize All GPU Cards

iRender has compiled several practical solutions that have proven effective in getting render engines to make full use of all available GPU cards. You can try each method one by one to see which one works best in your specific case:

  • Switch between CUDA and OPTIX rendering modes.
  • Update to the latest GPU driver—or try downgrading to a previous version.
  • Enable or disable Hardware-accelerated GPU scheduling in your system settings.
  • Disable CPU rendering. In some engines like Redshift or Blender, enabling both GPU and CPU rendering can actually slow things down, and may prevent some GPUs from operating at full capacity. Turning off CPU rendering often helps resolve this issue.

If none of these workarounds resolve the problem—either some GPUs are still inactive or their usage levels are uneven—the underlying issue may be related to the CPU or the complexity of the scene.

Even in GPU rendering workflows, the CPU plays a vital role in sending necessary data to the GPUs. If your GPUs are significantly more powerful than the CPU, a bottleneck can occur where GPUs are forced to wait for the CPU, resulting in idle time for some cards.

Additionally, if the scene you’re rendering is relatively simple, it may not be demanding enough to fully utilize all GPUs. In such cases, consider rendering on a system with fewer GPUs to ensure more efficient hardware usage.

How to render animation in Blender 3D?

Blender is a powerful, free, and open-source 3D creation software supported by a large and active community. Starting your journey with animation in Blender is a great choice, especially if you’re new to this field.

The Most Useful Tools

Before jumping into animation in Blender, it’s a good idea to get familiar with some essential tools that will make the process easier and more efficient. 

  • Constraints: 

Constraints are used to control how an object moves, rotates, or scales by linking it to another object or rule. They help automate complex motion, so you don’t have to animate everything manually, saving time and increasing realism.

  • Motion paths: 

Motion Paths show the route an object or bone takes during an animation. This visual guide helps you fine-tune the movement and timing by showing where things go frame by frame.

  • Drivers: 

Drivers let you control one property using another. For example, if you’re animating a clock, you can set up a driver so the hour hand moves automatically based on the rotation of the minute hand—no need to animate both separately.

  • Shape keys: 

Shape Keys allow you to modify the shape of a mesh and blend between those shapes. They’re commonly used for facial expressions like smiling, blinking, or frowning. Combined with keyframes, Shape Keys bring characters to life.

  • Rigging: 

Rigging creates a digital skeleton for your 3D model, allowing it to move in realistic ways. For example, rigging a human model helps joints bend naturally, which is essential for character animation.

  • Keyframes: 

Keyframes mark specific positions or values at certain points in time. To animate something like a bouncing ball, you would insert keyframes at different frames to show where the ball is—on the ground, in the air, and back down again.

  • Grease pencil: 

Grease Pencil lets you draw directly in 2D or 3D space. It’s perfect for sketching, storyboarding, or creating full 2D animations with layers, brushes, and editable strokes.

By learning and practicing with these tools, you’ll be well-prepared to handle many creative tasks involved in animation in Blender.

2D Animation in Blender

How to render animation in Blender 3D 2

Here’s a simple guide to help you start making your own 2D animation in Blender:

1. Launch the 2D Workspace

Open Blender and select “2D Animation” from the screen. This will bring you directly into Blender’s dedicated 2D animation workspace, which is quite different from the typical 3D layout.

2. Start Drawing with the Grease Pencil

First, switch to Object Mode from the menu in the top-left corner. Then, create a Grease Pencil object, which acts as your drawing surface.

Next, change the mode to Draw Mode using the same drop-down. In this mode, you can begin sketching using Blender’s drawing tools.

Use the Grease Pencil to draw your characters and backgrounds. You can customize your brushes—adjusting thickness, opacity, and style—just like in most digital drawing apps. Be sure to add colors to bring your drawings to life!

3. Add Animation Using Keyframes and Motion Paths

Once your drawing is ready, it’s time to animate!

  • Select your drawing, press I to insert a keyframe for its current position.
  • Move the timeline to a new frame.
  • Then draw a new pose and hit I again to insert another keyframe.
     Repeat this process to build up your character’s motion across frames.

For smaller objects or repeated elements, you can animate them using motion paths and keyframes without redrawing every single frame.

To enhance your animation, consider adding some visual effects—like a blurred background for depth or camera movements to add energy and focus.

4. Preview and Final Render

Use the Play button in the timeline to preview your animation in real time.

For a quick preview, go to the View menu and choose “Viewport Render Animation”. This lets you check the animation without fully rendering it.

Once you’re satisfied, follow Blender’s rendering process to produce the final animation file.

If you want a visual guide, check out the video “Blender 2D Animation Basics for Beginners – Grease Pencil Guide” by PolyPaint for a great walkthrough of the process.

3D Animation in Blender

Here’s a step-by-step overview to help you get started with creating 3D animation in Blender:

1. Start a New Project

To begin, open Blender and create a new project by going to the File menu, hovering over New, and selecting General. This sets up the workspace for 3D animation in Blender, not 2D.

2. Import and Prepare Your 3D Model

Bring your 3D character or object into Blender by navigating to File > Import. Choose the correct format (e.g., .obj or .fbx), locate your model, and click Import.

Once the model is in your scene, you’ll see it placed in the 3D viewport. You can import more objects as needed to build your scene. Set up lighting using Blender’s lighting tools to enhance the look of your environment.

To animate facial expressions or mesh changes, use Shape Keys to create various versions like smiling or blinking.

3. Animate with Keyframes and Animation Tools

Use Blender’s animation features—such as Constraints, Motion Paths, Drivers, and Keyframes—to bring your models to life.

  • Go into Object Mode and press I to insert a keyframe, or go to Object > Animation > Insert Keyframe.
  • Place keyframes at different moments in time to define the movement or transformation of your model.
  • You can set keyframes for position, rotation, and scale—and even name them if your animation gets complex, making it easier to manage.

4. Refine Your Animation

Go through your timeline and tweak your keyframes to make the motion smoother. You can adjust the interpolation type (e.g., linear, bezier) to control how movement transitions between keyframes. Don’t forget to animate smaller details to give your work a polished feel.

5. Add Sound and Camera Motion

To include sound in your animation:

  • Switch to the Video Sequencer from the top-left editor menu.
  • Press Shift + A, select Sound, and load your audio file.
  • You can drag the sound strip along the timeline to sync it with your animation.

Adding camera movement also helps bring your scene to life. You can animate the camera just like any other object using keyframes.

6. Preview and Render

Before final rendering, use Blender’s Viewport Render Animation option to preview your scene and make any necessary tweaks. Since rendering can take time, this helps catch errors early.

When you’re happy with the result, let’s render the full animation. You may want to check some tips to optimize Blender Cycles and Eevee for fast rendering here.
