Best multi-GPU render engines for Blender

Rendering is essential for any 3D artist’s workflow. It’s crucial to have a fast and efficient render engine to produce high-quality renders quickly, allowing for increased productivity and timely deliverables. Blender, a widely used open-source 3D software, supports multiple render engines that can leverage multiple GPUs’ parallel processing power to speed up rendering times. In this article, we evaluate and compare Blender’s top render engines optimized for multi-GPU configurations. Let’s dive in!

Blender and its supported multi-GPU render engines

Blender

Blender is a widely used, open-source 3D creation software that supports the entirety of the 3D pipeline from modeling, rigging, animation, simulation, rendering, compositing, motion tracking, and video editing to game creation.

One of Blender’s key advantages is its ability to support multiple render engines. Its open-source nature allows developers to create and integrate new render engines into the software, making it a highly customizable and extensible platform. 

A significant benefit of Blender’s support for multiple render engines is its ability to support render engines that can harness the power of multiple GPUs. By leveraging multiple GPUs’ parallel processing power, these render engines can speed up rendering times, allowing artists to produce high-quality renders quickly. This is particularly important for 3D artists who require fast rendering times for increased productivity. 

By providing a flexible and powerful toolset that can be tailored to their specific needs and workflow, Blender has become an ideal choice for 3D creation and rendering.

What to look for in a multi-GPU render engine for Blender

When choosing a multi-GPU render engine for Blender, there are several key factors to consider. Below are some of the most important ones. 

    • Pricing: The render engine’s pricing model, includes one-time purchases, subscriptions, and free options.
    • Integration Type (plug-in, built-in): can affect its performance and compatibility with Blender. Built-in engines are generally more stable and better integrated, while plug-ins may offer more features and flexibility, but usually require additional setup.
    • Render engine type  (biased, unbiased): Biased engines are typically faster but may sacrifice some accuracy, while unbiased engines are more accurate but may be slower.
    • Rendering Technology (OpenCL, CUDA, OptiX, HIP, etc) and GPU Compatibility: The rendering technology and GPU compatibility of the render engine can affect its performance and compatibility with different hardware configurations.
    • Ease of use: The render engine’s user interface and ease of use, especially for artists who are new to rendering.
    • Performance: The render engine’s ability to utilize multiple GPUs efficiently and render scenes quickly.
    • Supported OS and Blender version: can affect its compatibility with different OS, and Blender versions, thus increasing or decreasing the scope of use for a render engine.

Pros: 

    • Unbiased: produces physically accurate and realistic render results. Octane generally provides cleaner, sharper results out of the box. It’s better for product design which requires the highest physical accuracy. 
    • Multi-GPU support for a faster rendering process. 
    • Excellent Multi-GPU rendering performance and scalability: OctaneRender scales almost perfectly with multiple GPUs. In other words, if you use two GPUs, your renders will complete twice as fast as they would with just a single GPU.
    • Free version available (with limited features).
    • Advanced rendering features: Octane supports a wide range of advanced rendering features, including motion blur, caustics, displacement mapping, subsurface light scattering, volumetric rendering, hair and fur rendering, physical sky and sun, etc. 

Cons

    • Monthly subscription: OctaneRender is a commercial render engine. To access Octane’s full features, users need its license. 
    • Hardware compatibility: Octane supports CUDA, and thus only works with NVIDIA GPUs. This limits the GPU choice for its users. 
    • Plug-in: requires additional setup.

LuxCoreRender

LuxCoreRender is a physically based and unbiased open-source render engine. Based on state-of-the-art algorithms, it simulates the flow of light according to physical equations, thus producing realistic images of photographic quality.

Pros:

    • Free: can be used on commercial projects, a great choice for artists on a budget.
    • Open-source: easy to customize it to fit your specific pipelines and contribute to the project if you have the needed coding skills.
    • Unbiased: produces physically accurate and realistic render results. 
    • Multi-GPU rendering support for a faster rendering process. 
    • The design philosophy of LuxCoreRender is a no-holds-barred, fully physically accurate model when computing the render. As a result, it gives some of the most impressive and accurate results out of the box. It also outclasses traditional path-tracers like Cycles with a bevy set of features in place to compute light information even in the most challenging scenes. This makes LuxCoreRender incredibly potent for rendering scenes that focus on heavily refractive objects and caustics, or dimly lit interiors.
    • King of caustics, great SSS.

Cons:

    • Pretty complicated and has many options, but a lack of solid documentation.
    • Limited Blender versions support: Stable LuxCoreRender only works with older Blender versions.  
    • Not a production-based render engine, so there are no provisions for animation and/or temporal accuracy (for example, flickering prevention) for animations.

Radeon ProRender

AMD’s Radeon ProRender is a powerful physically-based path-traced render engine that allows professionals to create stunningly photorealistic images. 

Best multi-GPU render engines for Blender with iRender 06

How To Improve Speed Of Blender’s Cycles X Rendering Engine

Cycles X is essentially a set of improvements to Blender’s Cycles X rendering engine. It was announced on April 23rd, 2021 by the Blender Foundation. The ‘X’ on Cycles X represents the number ten. Cycles render engine is celebrating its tenth anniversary. It ships with Blender version 3.0 and later. The core was rewritten from the ground up to render much faster than Cycles’ render engine. Furthermore, the new core makes it easier for Blender developers to add future improvements.

In today’s blog, we’ll look at some of the settings you can change to speed up the Cycles X rendering engine.

1. Enable GPU rendering in your Blender’s user preferences settings

GPU rendering allows you to use your graphics card instead of the CPU to render. Modern GPUs are built to handle a lot of number crunching, which can significantly speed up rendering. However, due to relatively limited memory, they have limitations in producing complex scenes, as well as interaction issues when using the same graphics card for display and rendering. It all depends with the graphics card you are using.

How to enable GPU rendering in Blender version 3

Go to Edit > Preferences > System.

If you have an Nvidia graphics card, select either CUDA or Optix. If you have an AMD graphics card, select HIP. Then select your graphics card.

2. Optimize your Light Path settings

Light bounces are Cycles engine’s way of simulating the natural properties of light and how it reacts, or bounces, on walls and other objects. It’s what helps the rendered scene look so realistic when compared to the viewport. The problem with realism is that it requires longer rendering times. Light bounces are one of the most significant causes of a slow render.

This is easily fixed by navigating to the Render Properties panel in Cycles and then to the Light Paths section. Turning down the Max Bounces total can quickly speed up rendering. The default setting is 12, but anywhere between 3 and 6 will give you the same amount of realism without overworking the GPU when it comes time to render.

Cycles X rendering
Source: gachokistudios.com

You can fine-tune the lighting setup even further by adjusting the individual light path types, such as Glossy or Diffuse, which are also be found in the Light Paths section. Transmission should not be changed too much because it will reduce the final render’s realistic quality.

3. Activate Blender’s Persistence Data

Here’s how it works: When you press the render button, the first frame of your scene is calculated and cached. The frames that follow rely on the cached data from the first frame. This can sometimes speed up your renders by up to 5 times. Because your scene’s elements are no longer calculated in every frame, as they were previously.

Limitations of Persistent data

  • Persistent data performs best in static scenes. Scenes in which no objects move. As an example, consider an interior architectural rendering. As of now, the Persistent data feature does not support caching animated objects in the scene.
  • Persistent data comes at a cost of increased memory usage.

How to activate Blender’s Persistent data

Under render properties, go to the Performance Tab then the subtab ‘Final Render’

4. Optimize your HDRI multi-importance sampling

When working with high-resolution hdr environments, Blender can become very unresponsive when the hdri is first loaded. This is due to the time required to create an importance map that Cycles X needs to avoid fireflies during rendering. The importance map informs cycles about the bright areas of the hdri so that it can favor those join renderings and produce a better result.

How to optimize your HDRI multi-importance sampling in Blender

Go to the World settings > Settings tab. Change the ‘Sampling’ setting from Auto to Manual. Now, adjust the ‘Map Resolution’ value as needed.

Cycles X rendering
Source: gachokistudios.com

You simply need to set it high enough to avoid fireflies but low enough to prevent Blender from responding inaccurately. I’ve found that values of 512 and 1024 work best for me.

5. Set a render region when working on shading or lighting of a single object

You can improve viewport rendering tremendously when doing shading or lighting a single object. Because cycles will concentrate all resources to the render region instead of the whole viewport. Since a selected render region is smaller than the viewport, cycles will render the region faster.

To select a render region, click Ctrl+B. Then with your mouse draw a box around the object you would like to view as rendered. Below is a .gif to help you select a render region in Blender.

6. Reduce your Cycles X sampling count

Sampling is a render setting in Cycles X rendering engine. It is basically the number of light calculations Cycles X needs to do, in order to render a scene. The higher the samples count, the more accurate light calculations will be. The higher the samples count, the cleaner your render will be. Unfortunately, the higher the sample count, the longer your render time will be.

More samples are generally good. But there comes a point where more samples do almost nothing. Therefore, it is important to do test renders to come up with the sample count that will reduce your render time at the same time produce clean renders.

In Blender 3, you can set Noise Threshold, Max Samples, Min Samples and Time limit. To set samples count, go to Render Properties > Sampling > Render.

Cycles X rendering
Source: gachokistudios.com

For Noise Threshold, Min Samples and Time Limit values, leave them as default. Adjust Max Samples value from around 500 samples adjusting upwards until you are satisfied with the quality of render.

Cycles Render Improvements in Blender 3.0

Blender has finally leveled up. On December 3, 2021, the Blender Foundation released Blender 3.0 – the first total version change for the incredibly powerful and widespread open-source visual software in over 21 years. There’s a lot of good new stuff in this release, so in the article today, iRender put together a list of standout facets and features – the biggest and most notable changes – in Blender 3.0 here and find out the best way to speed up the new Cycles.

Cycles
Blender.org

The notable new features

1. Better shadows

Improvements to shadows came up a couple of times in the release notes, both in the renewed Shadow Catcher and Shadow Terminator.

Cycles
Blender.org

The shadow catcher now includes indirect and environment light support, and a pass that can maintain an object’s color when cast. The Blender Foundation says this makes it easier to blend images with real footage.

On the other side of things, the shadow terminator is making clearly digital designs seem just a touch more natural. Blender 3.0 has a new option to eliminate shadow artifacts in low poly models by offsetting rays to act on rigid designs as they would smooth surfaces.

2. Asset browser

The developers have put some serious effort into simplifying workflows for Blender 3.0 and, aside from fields, that shines brightly in the new and improved Asset Browser.

Cycles
Blender.org

The new asset browser is a drag-and-drop system that organizes objects, textures, lighting, and poses into catalogs with the ability to add metadata like authors and tags for further simplicity. The assets can be accessed across project files, so users can build up large personal repositories – more features are planned for future updates. The Blender Foundation has said this is simply the “first milestone” for the asset browser and that we can expect a series of “Blender Bundles” soon.

Poses received special attention in the release notes as a time-saving function for animators, too. They can be accessed via the asset browser or the animation panel in 3D view where users can “add, blend, flip, apply, and save different poses.”

Blender speed comparision

Blender 3.0 marks the beginning of a new era for 3D content creation, with new features including a more responsive viewport, reduced shadow artifacts, an asset library to access owned and borrowed assets quickly, and additional customization options. Speaking of Cycles, changes to GPU kernels and scheduling have resulted in “rendering between 2x and 8x faster in real-world scenes”, the Blender Foundation says.  Cycles renderer has been completely overhauled, maximizing NVIDIA RTX GPU RT Cores for OptiX ray tracing and Tensor Cores for OptiX AI denoising. This enables rendering nearly 12x and 15x faster than with a MacBook Pro M1 Max or CPU alone, respectively, with the GeForce RTX 3080 laptop GPU.

nvidia.com

Now, let’s check out the comparison between the render speed of Blender versions, with the BMW project.  Here’s a look at CUDA and HIP performance in 3.0.0 vs. CUDA and OpenCL in 2.93.7:

Cycles
techgage.com

It’s interesting to see that AMD appears to benefit more from this Cycles upgrade than NVIDIA, as its before and after deltas are much starker. The new Cycles especially breathes more life into AMD’s lower-end stack, where GPUs like the RX 6600 and RX 6600 XT effectively see doubled performance! Fortunately, these Cycles improvements extend beyond CUDA and HIP. The CPU also sees some improvement, just not to the extent that we see from the GPUs. And, because GPUs are clearly the most important focus for Blender rendering, CPU gains won’t ultimately matter that much for most people.

The new Cycles even benefits OptiX, not just CUDA. The performance delivered with the new Cycles X is simply staggering. In 3.0, some NVIDIA GPUs become as fast when rendering with CUDA as they were in 2.93 using OptiX (for example RTX 3090, RTX 3080). It takes things one step further again, giving us some seriously impressive performance.

The Best GPU For Blender 3.0

For this article, we’re benchmarking with the BMW, Classroom, as well as the brand-new Blender 3.0 official project, Sprite Fright.  “Sprite Fright” is no doubt the beefiest project to be found on Blender’s demo files page, requiring upwards of 20GB of system memory after it’s opened. Since projects like BMW and Classroom are pretty simple in the grand scheme, we’re happy to be able to now include a comprehensive project like this to test with.

All of the benchmarking conducted for this article was completed using updated software, including the graphics driver. An exception to the “updated software” rule is that for the time-being, we’re choosing to stick to using Windows 10 as the OS, as Windows 11 has so far felt like a chore to use and benchmark with.

These three sets of results all show similar scaling, with NVIDIA’s GeForces ultimately leading in performance vs. each model’s respective Radeon competitor. Of these four projects, it’s the Sprite Fright one we were keen to analyze most; not just because it’s brand-new, but also because it’s the most complex Blender project we’ve ever tested. As mentioned above, merely opening the project will use upwards of 20GB of system memory.

Sprite Fright‘s resulting render is effectively three renders in one, with each being layered on top of the others in the final composition stage. Due to this design, there’s a slight delay in GPU work in between each of those renders, so we opted to retain default sample and resolution values to make sure the CPU wouldn’t interfere too much with our scaling. That leads to a super-fast GPU like the RTX 3090 taking 10 minutes to render a single frame, and a lower-end RX 6600 taking over 40 minutes.

Conclusion: In NVIDIA’s current-gen lineup, we’d have to say that the GeForce RTX 3090 and the video memory of 24 GB VRAM are the best bang-for-the-buck, given its pricing and performance delivered. Try it here.

Render Faster With Multi-GPU in Blender & Cycles

As you might know, EEVEE has real-time rendering capabilities that save you a lot of time in post-production, while Cycles is very flexible and brings great realism to the project, not for speed. However, with Multi-GPU settings, Cycles can nevertheless deliver an impressive level of render speed.

In this article, iRender will bring you deep knowledge about GPU rendering in Blender & Cycles. Unfortunately, GPU rendering is only supported on Windows and Linux; macOS is currently not supported.

Multi-GPU Rendering for Blender & Cycles

Supported Graphic Cards

Always make sure to install the latest drivers from the graphics card manufacturer website. These requirements are for basic Blender operation, Cycles rendering using the GPU has higher requirements.

NVIDIA: GeForce 400 and newer, Quadro Tesla GPU architecture and newer, including RTX-based cards, with NVIDIA drivers (list of all GeForce and Quadro GPUs)

AMD: GCN 1st gen and newer. Since Blender 2.91, Terascale 2 architecture is fully deprecated, try using 2.90 (albeit not supported, it might still work) [list of all AMD GPUs]

Intel: Haswell architecture and newer. [list of all Intel GPUs]

Recommended Graphic Cards

Blender’s heavy use of GPU acceleration and its rock-solid CUDA implementation makes an Nvidia graphics card a safe choice for most users. Non-CUDA cards (read: AMD cards) aren’t the best choice for rendering, but they’re still a good choice for users interested in consistent viewport performance.

If you navigate your Scene a lot by moving around the camera in Blender or playing back animations, Nvidia GPUs are a solid choice because CUDA usually supports more features and performs better. Blender’s development team is actively working with Nvidia to fully integrate OptiX features into Blender and OptiX accelerated CUDA rendering already is available alongside the existing CUDA and OpenCL implementations.

When it comes to looking at GPU specifications, pay attention to the number of compute-cores (CUDA or OpenCL, depending on what brand you buy) and the amount of VRAM. Blender is just as hungry for VRAM as it is normal RAM, and a GPU with ample VRAM is worth paying extra for if you’re interested in sculpting, high poly modeling, or GPU rendering.

Over the past three years or so, NVIDIA’s dramatically improved the rendering performance in its stack. It was once exciting when the BMW project broke through the 60-second barrier, but now we have these new RTX GPUs cutting through the 30-second mark. The RTX 3090 comes closer to 20 seconds than it does 30 seconds. These new GPUs are really, really fast.

For all the reasons mentioned above, we definitely recommend:

  • Performance Pick: Nvidia RTX 3090 or RTX 3080
  • Value Recommend: Nvidia RTX 3060 Ti and RTX 3070
  • Budget Choice: Nvidia GTX Model

Multiple GPU support for Blender & Cycles

You’ll need a GPU with lots of CUDA Cores or Stream Processors for fast GPU Rendering and can add multiple GPUs for a near-linear increase of GPU Render Performance. Blender can take great advantage of multiple GPUs, delivering dramatic gains when a second card is added. 

Using more than one GPU will certainly speed up Cycles. In User preferences -> System -> Compute device, you can configure which Cuda devices to use. When rendering, each GPU will render one tile (following the settings on the performance tab). The more GPUs, the more tiles are rendered simultaneously, so dual GPUs will make a huge difference in Cycles by decreasing rendering time by almost one-half.

In some cases of GPU rendering, mainly on previous versions of Blender 2.8, the whole system slowed down and became quite responsive. This issue has been fixed since version 2.8. Other than rendering, only one GPU will be used for many parallel tasks, both computing and rendering, which means that it does not even promptly process the displayed image on the interface of the operating system. Therefore, using multiple GPUs can resolve the slowdowns or lag problem, since the graphics processor will divide GPUs to render while the user can continue to use the PC for other things.

Render scaling of Blender & Cycles

Render scaling of Blender & Cycles

In the chart above, it is clear to see that Cycles scales quite well when adding more GPUs. There’s no reason to stop at 4 GPUs out of fear of diminishing returns. Unless you’re typically rendering at samples less than 200, you’re better off with more than 4 video cards if your motherboard can handle it and you can afford the cards.

Second, scaling doesn’t need to be expensive. Let’s find out the solution we provide you in the next part.

NVlink Support

If you use less memory/video memory, Blender may take a long time to complete rendering or it appears CUDA error: Out of memory. For massive scenes requiring a lot of memory, it is an incredible resource. There are two ways to solve this problem:

  • Method 1: Smaller resolution textures

One way to reduce memory usage is by using smaller resolution textures. For example, 8k, 4k, 2k, and 1k image textures take up respectively 256MB, 64MB, 16MB and 4MB of memory.

  • Method 2: Use NVlink

One crucial field for architectural visualization that is about to get some significant updates is Cycles when working with multiple GPUs. Today, you could easily use more than one GPU for a rendering in Cycles, which would split the load. Each GPU could handle part of the rendering, which cut in half your render times in many cases.

The main problem with that solution in Cycles, when using “old” interfaces like SLi (for NVIDIA), is that your GPUs would still act as two different cards. A new technology from NVIDIA called NVLink is different and can make multiple cards work like a single one. That is also valid for available memory.

To connect the cards, you need an additional piece of hardware called a bridge. For instance, if you want to go for an overkill setup, a dual GeForce RTX 3090 connected with the NVLink, the final amount of memory available for your scenes in Blender will be 48 GB.

System Requirements

1. Cinema 4D version

Cycles 4D will work in these Cinema 4D versions:

  • R14
  • R15
  • R16
  • R17
  • R18
  • R19
  • R20 (using the Insydium Bridge plugin, which is supplied with Cycles 4D)
  • R21 (also using the Insydium Bridge plugin)

2. Operating system

  • Windows: The minimum requirement is 64-bit Windows 7 or a later version.
  • Mac: OSX 10.10 Yosemite is the minimum recommended version to use with the Cycles engine.

3. Graphics cards

  • NVIDIA: Cycles 4D is compatible with all PC systems using an NVIDIA graphics card and will render using the GPU.
  • AMD: Previous versions of Cycles 4D used OpenCL to render using the GPU on AMD cards (and OpenCL support was also available for NVIDIA cards). Due to a lack of support from Apple, Blender has withdrawn OpenCL compatibility on macOS, meaning that GPU rendering is not available using AMD cards on these systems.

4. Internet access

Cycles 4D must validate your licence after installation and from time to time after that. Therefore to use it your machine MUST have access to the internet before you use it for the first time and sufficiently often after that to enable repeat validation. It does not require constant net access all the time.

Eevee Rendering In Blender & Advanced Techniques

Since the introduction of Blender 2.8, Eevee has replaced the old Blender ‘Internal’ Renderer. Eevee is focused on real-time rendering, using clever speedy tricks to sacrifice as little realism as possible when compared to Blender’s realistic Cycles renderer.

In the article today, iRender will step it up and cover four advanced settings and properties of EEVEE Rendering in Blender.

1. Indirect Lighting

Eevee is optimized for speedy rendering, not for realism, like the Cycles renderer. But with the right settings, Eevee can nevertheless deliver an impressive level of realism.

One of the most significant differences between Eevee and Cycles is that Cycles calculates bounced light rays in a scene, also known as global illumination (GI) or irradiance, using a technique called path tracing. To make Eevee calculate bounced light you need to add an Irradiance Volume. To do this, press Shift + A, go to the Light Probe submenu and choose Irradiance Volume.
A box-shaped gizmo with a 3D matrix of points appears.

Eevee Rendering In Blender & Advanced Techniques 1

Image Source: cgcookie.com

The Irradiance Volume should be placed in such a way that the bottom of the inner cube is just below the floor of your scene, so the 3D matrix of dots is surrounding the scene’s important elements. The dots are points in 3D space where the properties of bounced light (energy level, colors) are sampled and then rendered on nearby surfaces.

The distance between the inner box gizmo and the outer box gizmo indicates the area in which the irradiance effect will fade out. This can be influenced by adjusting the Distance and Falloff settings in the Irradiance Volume gizmo’s Object Data Properties.

Eevee Rendering In Blender & Advanced Techniques 2

The next step is calculating the irradiance. Go to the Indirect Lighting section in the Render Properties and press the Bake Indirect Lighting button.

Eevee Rendering In Blender & Advanced Techniques 3

Image Source: cgcookie.com

After a short moment of calculating the irradiance will be added to the scene. The results are usually subtle, but increase the scene’s realism.

Eevee Rendering In Blender & Advanced Techniques 5

Image Source: cgcookie.com

As you can see, the red color of the floor has bounced onto the monkey head. The accuracy of the bounced light can be improved by increasing the Diffuse Bounces, Cubemap Size, and Diffuse Occlusion values, at the expense of longer irradiance calculation times.

It is important to note that the bounced light that’s calculated by an Irradiance Volume gizmo is a one-time calculation, and is not updated with each animation frame. This means that if your scene changes during an animation, the calculated bounced light will become less correct or even obsolete.

2. Emissive Objects

If you’re using Cycles, you can turn any object into a light source by assigning a material containing an Emitter shader. In Eevee, such a material does not work unless you calculate the irradiance using the aforementioned steps, because the light from emissive objects needs ray calculations from each normal angle of the object’s faces.

In the example images below, an emissive material has been assigned to an icosphere. As you can see no light is emitted from the icosphere object without irradiance. The Screen Space Reflections do reflect the icosphere without irradiance.

Image Source: cgcookie.com

Again: the accuracy of the indirect light calculations can be improved by increasing the Diffuse Bounces, Cubemap Size and Diffuse Occlusion values, at the expense of longer irradiance calculation times.

3. Glass and Other Refractive Materials

Establishing a refractive volume in Cycles, such as glass, is easy: just turn up the Transmission value of the default Principled BSDF material (to a value of 1 for the full effect), and Cycles starts transmitting rays through the material to render convincing glass or transparent plastic.

Eevee is not a path tracing renderer but works by performing speedy trickery, so if you turn up the Transmission value of the monkey’s default Principled BSDF material, this is what happens:

Eevee Rendering In Blender & Advanced Techniques 7

Image Source: cgcookie.com

To get you going, here are some common Index Of Refraction values:

  • Air = 1.0
  • Water = 1.325
  • Milk = 1.35
  • Plastic = 1.46
  • Glass = 1.5 (average value, depends on the type of glass)
  • Crystal = 2.0
  • Diamond = 2.418

4. Sub-Surface Scattering

Another eye-catching effect is sub-surface scattering (SSS). This mimics the way light rays are absorbed and scattered inside a volume, causing thin parts to transmit more light than thicker parts. Think of the blood-red color you can see through your fingers if you shine a bright flashlight behind your hand. Once again, Eevee needs to establish the illusion of SSS using a smart, speedy technique instead of hardcore ray-tracing. And Eevee does this quite well. Let’s activate SSS in Eevee:

First, head to the Render Properties ➔ Subsurface Scattering section, and increase the values a little for a finer result.

Image Source: cgcookie.com

More samples refine the SSS calculations, and a higher Jitter Threshold prevents a possible pattern caused by the algorithm. Don’t increase the values too much if you want Eevee to remain speedy/real-time.

The next steps are performed in the Shader Editor, adjust the following items in the default Principled BSDF material.

Image Source: cgcookie.com

  1. Usually, you’ll want the Base Color (the surface color) to be different from the Subsurface Color.
  2. Set the Subsurface value to 1.0 to exaggerate the effect.
  3. Depending on the scale and volume of your object you can adjust the Subsurface Radius values. These are essentially RGB values, so the default settings of 1.0, 0.2, 0.1 cause a red SSS color.
  4. To further emphasize the SSS color, turn the Subsurface Color to red as well.
  5. For a final bit of refinement, activate the Subsurface Translucency option in the material settings.
  6. Make sure the Screen Space Refraction option is unchecked, or the refractive properties will override the SSS effect.

You will see that Eevee SSS can create quite a nice candle wax material, but SSS is also very useful for achieving convincing skin, plastics, milk, orange juice and much more.

The Best Cloud Rendering for EEVEE

Eevee is only going to make use of one of graphic card. The reason is that multiple graphic cards CANNOT work together to render a single frame using rasterization which is what Eevee uses , so it will perform best when it benefits from high VRAM capacity. If EEVEE is your primary application, then we recommend using NVIDIA Geforce graphics cards as they generally have higher performance at a lower cost. The best NVIDIA GPUs for Rendering are:

Let’s check the NVIDIA Geforce performance in Blender EEVEE:

Keep this in mind, iRender provides server 3 owning Xeon W-2245 CPU Processor with a high clock speed of 3.9 GHz- 4.7GHz and 512 GB SSD to specifically support the software only make use of a single card. This server comes with the latest RTX 3090 card from NVIDIA with the VRAM capacity up to 24GB.

With the above advantages and the machine configuration package that iRender has released, we believe that EEVEE users will have the most comfortable and effective rendering time.

There are two outstanding features: Real-time effects in the viewport like BLOOM and Tone Mapping help bring your art to the next level with ease and immediate results. Plans for adding even more features to the K-Cycles engine. Now let’s find out what’s new and interested in this new render engine?

K-Cycles Bloom

  • K-Cycles Bloom is the only Cycles implementation of Bloom in the viewpoint.
  • BETTER implementation of Bloom than the compositor, many more controls for manipulating your bloom PLUS more accurate bloom as well.
  • EASY to use and works just like you would expect.

A feature that Eevee users have used and enjoyed is now available with K-Cycles. Dynamically interact with the scene in the viewport. Adjusting quickly the Bloom settings with fast performance in the preview render viewport. Creating beautiful Bloom effects in no time. The Bloom settings has all the options that are needed to design and easily create and customize your Bloom effect. K-Cycles has higher quality while Eevee blurs and loses the light definition. See below:

Revolutionize K-Cycles with powerful cloud rendering service

There are very few render farms that support K-Cycles rendering because it only delivers world-class performance and impeccable visuals when paired with the newest NVIDIA RTX – based hardware, which is very difficult for many farms who are offering the different lines (Tesla, GTX , etc) or different video cards (AMD). Besides, it is a totally new render engine and is not popular yet to find on render farms. However, we are proud that we support K-Cycles very well. iRender provides you a personal cloud computer with powerful hardware (100% performance – no virtualization). That means you can install any plugin or do render even from a laptop so long as you have a stable internet connection.

Although K-cycles works with both CPU and GPU, unfortunately, the CPU gains for K-Cycles are small compare to default Cycles. So I would not recommend using K-Cycles if your choice is CPU. Besides, we already found that K-Cycles has a very powerful performance with the RTX 3090 in the test above. Therefore, we offer a single card server of 1x RTX 3090 at a very affordable cost for customers who have frequent use needs. We highly recommend this option who Blender users working with small and medium projects.

Things that you should know to optimize Lumion 1

We understand that lock speed has the biggest impact on CPU performance with K-Cycles. That’s the reason we offer Xeon W-2245 CPU Processor owning a high clock speed of 3.9 GHz- 4.7GHz and 512 GB SSD to specifically support single-threaded tasks. This package also comes with the latest NVIDIA RTX 3090 card recommended and a VRAM capacity up to 24GB.

iRender has a great number of enthusiastic staff that are always ready to support you 24/7. Whenever you have trouble using our server, or even with your software, we – iRender Support Team are always there to help you solve your problem. We believe the quality of support we provide is as vital as the technology we deliver. We provide unmatched support tailored to your specific needs and goals. What IRAY users can get from iRender is not only the best quality products but also the high security and the most comfortable render time.

iRender is one of a few render farms providing a unique transfer file tool, without having to access a third party for transferring data. With this tool called GpuHub- Sync, you can upload your data even when the remote server is turned off and it will automatically sync to the remote servers and vice versa. We provide storage space of up to 1TB for you and most importantly it is completely free.

What you can get more from iRender?

Last but not least, price is an extremely important factor for users.

Photorealistic & High Speed E-cycles Rendering with Blender

Today I will continue sharing my series articles to read on the topic of render engines for Blender with the central question that drives my work, “Which is the fastest for this software?” To find the answer, iRender will bring you deep knowledge about one of these engines well known for speed: E-cycles Rendering.

Photorealistic & High Speed E-cycles Rendering with Blender 1

As you might know, EEVEE has real-time rendering capabilities that save you a lot of time in post-production. That is also the reason that many people choose it instead of Cycles for their projects. Cycles is very flexible and brings great realism to the project but many designers really do not have much time, so if ever use Cycles, then it will be E-Cycles. Developer Mathieu Menuet has released E-Cycles as a new solution to its predecessor, the accelerated version of Cycle render engine which he claims is the fastest and easiest photorealistic renderer for Blender. EEVEE might be good enough for some jobs, but if you really want to go professional, you will need E-Cycles.

E-Cycles 2021 - February update - New features and improvements

1. Speed E-cycles Rendering

It is undoubted that one of the greatest benefits is its fast speed, and that is exactly what I want to discuss in this article. The developer has other arguments than me about the benefit of speed. To every designer, time is money. To his argument, users save money by taking advantage of their graphics card. Both make sense.

Thanks to code optimizations, rendering with NVidia GPUs and E-Cycles is equivalent to doubling the number of GPUs in your machine, on average

E-Cycles - Persistent Data + RTX 3090 = 3 sec/frame

But it doesn’t stop there. Thanks to a new option called “Persistent Data“, for fly-through animations where only the camera moves, E-Cycles only needs to do the pre-processing step once for all frames. In the example above, rendering takes just 3 seconds per frame on a single GPU. In this case, the persistent data option saves 7 seconds of pre-processing per frame.

2. Light Groups of E-cycles Rendering

I am quite certain that the most interesting feature with Blender users is light-groups. Easy usage, higher-quality render. All you have to do is put lights (or groups of lights) in collections so that you can adjust the strength of the ambient light.

When you tweak lights in the viewport, it will restart at 0 samples by default each time you change a parameter. But when using E-Cycles and light groups, you can tweak your lighting setup while the viewport continues to render, offering you very fast, high quality previews.

3. Denoising of E-cycles Rendering

E-Cycles AI-Denoiser requires between 4 and 10 times less samples than other AI-based denoisers to get a similar level of quality. Using less samples for the same quality means a proportional speed increase for your renders – that’s on top of the ‘regular’ speed increase E-Cycles offers on NVidia cards. For comparable image quality, with both the regular speed increase and the new AI-Denoiser, you can get up to 25x faster rendering. And it’s a one click setup!

Marvin Luebke did a comparison test and the result is that Cycles with OpenImageDenoise takes 40 seconds to render (left)  and E-Cycles with its AI-Denoiser takes 9 seconds to render (right).

The most professional rendering service for E-cycles

1. Up to 3x faster than standard Cycles when rendering on Nvidia’s CUDA GPUs

According to Menuet, CPU rendering using Open Shader Language is also faster than Cycles, however, in fact E-Cycles is mainly intended for GPU rendering. 

It also works with AMD graphics cards running under OpenCL, although the speed boost is smaller: in Menuet’s tests, the standard scenes render 1.06x to 1.28x faster with a Radeon RX Vega 64. Our conclusion: E-Cycles renders much faster than the Blender master on a GeForce NVIDIA. Additionally, user’s results posted on Blender forum have proved that the speed boost varies from graphics card to graphics card. They suggest that the speed may be faster with more powerful or more recent GPUs of NVIDIA, for example: RTX 2080Ti, RTX 3070, RTX 3080, 3090.

In Menuet’s tests with the standard Cycles benchmark scenes, E-Cycles renders 1.23x to 2.42x faster than the Blender master on a GeForce GTX 1080 Ti GPU, and even 3.0x faster on RTX 2080Ti GPU.

2. Why is iRender the most professional rendering service for E-cycles?

There are very few render farms that support E-cycles rendering because it is not a popular render engine like its predecessor Cycles. Perhaps the reason is that Cycles is free while you have to buy a license with E-cycles. However, we are proud that we support E-cycles very well. iRender provides you a personal cloud computer with powerful hardware (100% performance – no virtualization). That means you can render or do any intensive task even from a laptop so long as you have a stable internet connection.

As you can see, at iRender, we offer a specific Multi-GPUs server for designers with a passion for Cycles, E-cycles, Octane, Redshift and more,… with different configuration options depending on your usage needs. An important thing to consider while building a rig for GPU rendering, is that all the geometry and textures will be loaded into the GPU memory, so 6 GB GPU-memory is a minimum. And if you want 6x render power, you can use a server with 6 GPUs instead of buying many computers and lots of single licenses.

In addition to the hardware powerful enough for the rendering process that mentioned above, iRender is always up to date with the latest card models from NVIDIA like RTX 2080 Ti, RTX 3080, RTX 3090 with VRAM from 10GB to 24GB totally satisfying for software that utilizes the power from multi-cards. They are also integrated with NVlink technology to expand data bandwidth between GPU and CPU 5-12 times faster than PCI Express interface. It can be used as a large memory pool for the GPU to display large and complex scenes.

Cycles 4D - A Wonderful Bridge Plugin From Cinema4D To Cycles

Cycles 4D acts as a bridge between Cycles and Cinema 4D. It is important to realise that the engine is developed by the Blender Foundation and not Insydium. Once the Cycles render engine is selected within Cinema, rendering to viewport or picture viewer is seamless and works exactly as if using Cinema’s inbuilt renderer. In addition Cycles 4D adds additional support for X-Particles so that particles can be rendered easily with Cycles 4D.

To simplify that, Cycles4D is both a CPU and GPU render engine that uses a way of calculating final rendered images that aims to be photorealistic and not taking shortcuts.

Advantages

  • Increase your workflow speed with Realtime Preview Window

Every third party render engine has an Interactive Preview Region window. The IPR allows users to see a rendered scene in almost real time. In Cycles4D it is named “Real-Time Preview.”

The Real-Time Preview window gives you a high-quality render which updates as you make changes in your viewport. The preview updates and cleans up incredibly quickly giving you an excellent idea and representation as to what the final render will look like on output.

  • PBR Shaders and HDR Lighting

Experience photorealism with Cycles 4D physically based shaders, designed to work with global illumination due to their energy-conserving behavior. High-definition-range lighting calculations allow the preservation of details often lost due to limiting contrast ratios.

  • X-Particles support

Cycles 4D lets you harness the speed and versatility of Blender’s Cycles render engine. Additionally, Cycles4D is also developed by Insydium, the company that also makes X-Particles for Cinema4D. This is a huge benefit compared to other render engines. 

Cycles 4D

Cycles4D has a direct link to X-Particles meaning if you do any kind of particle and simulation work, you’re going to get the best result from Cycles4D. Particles, fire, smoke, fluid sim rendering all right at your finger tips. It also includes native volume rendering of ExplosiaFX and Domain and full-color Support.

Disadvantages

  • The speed on AMD is not good

Yes, AMD graphics cards are supported. However, similar to his brother Cycles, they aren’t as fast as NVIDIA cards. This is really sad news for AMD users in general and Optix in particular.

If you select GPU rendering, Cycles 4D uses the graphics card’s memory when the scene is rendered. Since this is limited compared to the main computer’s memory, you may see out-of-memory errors when rendering. If you are rendering to the picture viewer, the render engine will automatically switch to the CPU to render the scene.

  • Node system
Cycles 4D

Cycles4D has a beautiful node interface, but we know how daunting that can be to a new artist. For those who are just starting to get used to the node system, it is a bit confusing and difficult to use.

How to speed up Cycles 4D?

1. CPU and GPU Rendering

Cycles 4D is able to use your computer’s central processing unit (CPU) or graphics card (GPU) for rendering. With the latest core update Cycles 4D now supports combined CPU and GPU rendering to harness all system cores for your final render.

CPU and GPUs are basically similar in how they are handled. The use of CPU and GPU Rendering depends on usage necessities. The architectural industry may benefit from CPU rendering, which takes longer, but generates higher quality images in general.

Cycles X

Moreover, industries that are specifically designed to manage complicated, graphics-intensive processing, virtual reality, and artificial intelligence innovation such as architecture, animation, film, and product design may benefit more from GPU rendering. The GPU is much more powerful and, unlike CPU technology they can process the instructions of many cores from start to finish at the same time. This will allow your render times at least 10 times faster.

To eliminate render wait times, you might consider investing in multi-core processors and GPUs with a high CUDA core count because GPU support makes it possible to accelerate your render speeds by the number of graphic cards in your system. 

2. Use iRender GPU Rental service

Unlike any of the other render engines we’ve featured, Cycles4D comes with the ability to setup a small render farm using three machines. If you have extra machines sitting around, you can setup a small render farm right out of the box without having to purchase more licenses. However, it is undoubted that you can not buy 3 machines at home to optimize Cycles 4D. Thus, to build a computer cluster and utilize your computer’s GPU, you will need an investment on their own… which brings us to our last tip: use CPU/GPU Rental Service of iRender.

iRender provides you a personal cloud computer with powerful hardware (100% performance – no virtualization). That means you can run intensive software like Cinema4D and Cycles4D even from a laptop so long as you have a stable internet connection.

New Blender's Cycles X Showing Insane Speed

Currently, there have been widespread and inconclusive discussions about a major upcoming rewrite of the software’s production renderer from the Blender. Unveiled on 23rd April by developers Brecht van Lommel and Sergey Sharybin, Cycles X is being announced to coincide with the renderer’s tenth anniversary.

We all know that Cycles are a physically-based, integrated render engine, unbiased path tracing rendering solution for Blender. The main feature of Cycles is path tracing, which is an algorithmic process of rendering images by simulating how light is reflected on an object. This algorithm detects its light paths from the camera rather than from the light source, making Cycles a sort of “reverse” path detector.

Cycles is always well-known as a great realism tool and EEVEE (Blender’s newer-time renderer) with amazingly fast speeds. However, for final-quality output, Cycles is still most Blender users’ main tool for photorealistic rendering, particularly for VFX and architectural visualization. That’s also the reason why the developer announced a rewrite of Cycles with a new name: Cycles X in order to address “longstanding issues” with the renderer, to make it easier to support new hardware, and to add more advanced features for production rendering. Cycles X is favored by the Blender Foundation as “future proof it for the next 10 years“.

CPU rendering with Open Image Denoise (OIDN)

Performance is always what is expected most after every revision of the render engine. To be honest, though, CPU rendering hasn’t changed much in Cycles X. CPU rendering performance is approximately the same as before at this point, but the new architecture opens up new possibilities there as well. Most of Blender users know that Cycles does not have good caustics support. It technically isn’t in the engine, and really isn’t very possible without a major overhaul. Cycles’s glass shader is far less advanced and not really designed to even have caustics. Which is why people use replacement shaders all the time.

However, there is an innovation. The developers also plan “more advanced algorithms” for volume rendering, caustics, and for sampling scenes with large numbers of lights. The new architecture should also make it easier to implement light groups. Additionally, CPU rendering with Open Image Denoise (OIDN) denoising enabled – which previously made the viewport almost unresponsive – has been noticeably improved.

When selecting a processor for Blender, usually the two key factors to consider are frequency and the number of cores the processor has. With this in mind, an Intel Dual Xeon or Intel Core i9 solution will be the suitable processors to meet your CPU requirements. However, you must be careful as this Intel Core i9 does not have the capabilities to support more than 2x graphics cards at full speed on its own. This fact leads to the solid choice, Dual Xeon, if you are using Blender with Cycles. The two processors working together generally provide plenty of expandability capable of supporting multiple graphics cards.

Cycles X

The entire machine of iRender is equipped with CPU Dual Intel Xeon E5 2678 v3 belonging to socket 2011-3 and owning 24 cores 48 threads thanks to Hyper Threading technology. The basic clock speed is from 2.4Ghz and Turbo Boost up is 3.3Ghz (clock speed of all cores is 3.0 Ghz). The L3 cache is 30Mb, combined with the QuickPath Interconnect (QPI) feature that allows operation on systems that support multi-socket with high bandwidth. Therefore, when running Dual CPU Xeon E5 2678 v3 on a main chip set, it will increase the maximum performance especially for those who specialize in rendering.

Up to 7x faster than the existing version of Cycles on Nvidia GPUs

Developers involved with Cycles X have been prototyping a new GPU kernel and early benchmarks of Cycles X with the NVIDIA OptiX back-end is looking very promising. In detail, , the standard Cycles-X benchmark scenes render is up to 7x faster than the existing version of Cycles on currently available Nvidia GPUs. The performance improvement over the Blender master branch varies from scene to scene – complex scenes, like interiors with a lot of bounced light will benefit most.

Cycles X

Unfortunately the OpenCL rendering kernels support is being removed. Dropping OpenCL support is sad news for AMD users and also the disadvantage of AMD Radeon and Intel GPUs. Besides, like its predecessor Cycles, GPU rendering is a solid choice for Cycles X: from single GPUs to multi GPUs. Based on the test results above, you must have seen that Cycles X combined with multi NVIDIA RTX cards will deliver a very impressive performance (up to 7x faster). In particular, the latest and best-selling names at NVIDIA will be the top priority choice to maximize the speed of Cycles X, including: RTX 2080Ti, RTX 3070, RTX 3070Ti, RTX 3080, RTX 3090, RTX A6000.

If you are travelling on a low budget, you can refer to the Single-GPU or Dual GPU server at iRender, and only 1/2x GeForce RTX 3090 (24GB VRAM) – the world’s fastest graphics card but also the world’s first to connect, create and watch video at 8K HDR – completely enough to optimize Cycles X.

Let’s take a look at the video test on 1x RTX A6000:

Cycles X - GPU viewport rendering (Source: www.blender.org)

However, if you are on the budget, it is undoubted that using multiple graphic cards will maximize render performance. iRender offers not only single but multi-card configurations for you to choose with a diversity of latest cards from NVIDIA: RTX 2080 Ti, RTX 3080, RTX 3090 and definitely far beyond Blender’s recommended GPU requirement.

Why iRender is the best choice for testing Cycles X?

1. iRender supports all render engines including Cycles X

In other popular render farms, the rendering process will depend on the project distribution on render farm through Farm Manager – the supplier’s farm management tool. Farm Manager only supports render engines and the versions that it provides. And since Cycles-X does not have an official version yet (expected to launch on Blender 3.1 about 6 months later), you are unable to test its performance on the normal farms. In addition, you do not have the ability to choose the optimal PC configuration you want for Cycles X.

At iRender, we provide our customers with an extremely unique rendering solution.

We offer physical machines – no virtualization with a specific Multi-GPUs server for designers using Redshift, Cycles, Octane, etc. You will install any software and render by whatever engine you want through Remote Desktop Application. Due to our Tier III standard Data Center, you are completely in control of your projects and test Cycles-X perfectly.

2. The only render farm save 50% for long-term use

Normally, the cost is calculated according to the actual time you use the machine: from the time you connect our server to the moment the computer is shut down.  But you can always save up to 50% with our Fixed Rental feature. For those who are in need of a server more than a day, or have extremely large projects, we advise to choose a daily/ weekly/monthly rental . The discount is attractive (30% for daily and  50% for weekly and monthly rental).

3. Real human support 24/7

Whether you are an iRender customer, or you are simply interested in our service, iRender has a great number of enthusiastic staff that are always ready to support you 24/7. Whenever you have trouble using our server, or even with your software, we -iRender Support Team are always there to help you solve your problem. We believe the quality of support we provide is as vital as the technology we deliver. We provide unmatched support tailored to your specific needs and goals. What CyclesX users can get from iRender is not only the best quality products but also the high security and the most comfortable render time.

Final thought

The source code for Cycles X is about to be released publicly as a branch of Blender and this  work is independent of other Cycles dev projects. Besides, the developers estimate that there is around six months’ more development work before the updated render can be rolled out publicly, which they expect to happen in Blender 3.1. Temporarily Cycles X still has experimental build. (alpha and beta) for users to experience here. You can always use a high-spec machine to do a test with Cycles X at a very competitive cost at iRender: only from $3.8 to rent a supercomputer with the RTX 3090.
