Octane Render has emerged as a leading choice for 3D artists and designers seeking high-quality, photorealistic renderings. Known for its real-time rendering capabilities, Octane leverages powerful GPU processing to deliver stunning visuals with remarkable speed. However, to truly harness the potential of this render engine, understanding its unique workflow and features is necessary. Whether you’re a seasoned professional or a newcomer to the world of 3D rendering, mastering Octane can elevate your projects significantly.

In this blog, iRender aims to provide essential tips and best practices for maximizing your efficiency and creativity while working in Octane. Let’s get started!

Managing scene complexity in Octane Render is crucial for maintaining optimal performance and ensuring efficient rendering times. Here are some strategies to effectively manage scene complexity in Octane:

Use Proxy objects

Proxies are simplified representations of high-polygon models. When using proxies, Octane only loads and renders the simplified version until you need to see the details. Convert complex models into proxies in your 3D software (like Blender, 3ds Max, etc.) and link them in Octane. This drastically reduces memory usage and speeds up interactive rendering.

Use Instancing

Instancing allows you to reuse the same mesh multiple times in a scene without duplicating the geometry in memory. It is perfect for objects like trees, rocks, or any repeated element. This is particularly useful in outdoor scenes or populated interiors.

Optimize Geometry

One of the ways to optimize your scenes is to Reduce polygon counts. You should simplify your models where possible and use lower-polygon versions of objects (LODs) for distant or less important elements. Tools for decimation or retopologizing can help. Moreover, if you have multiple identical objects (like trees or rocks), use instancing rather than duplicating geometry. Instances share the same data, saving memory and increasing performance.

In Octane Render, various light types such as Dome light, Area Light,Point Light, Spotlight are available to achieve different lighting effects and enhance the realism of your scenes. Choosing the right type of light in Octane Render is crucial for achieving the desired mood and realism in your 3D scenes. Each light type has unique properties and applications, so take the time to experiment with them to see how they can best fit your particular project needs. By effectively combining different light types, you can create complex and engaging lighting setups that enhance your visuals.

Furthermore, using high Dynamic Range Images (HDRIs) provide natural and ambient light to your scenes. They are often used in outdoor environments for realistic sky lighting, reflections, and soft shadows. When using HDRI, ensure it is properly mapped and adjusted for intensity.

Materials

In Octane Render, materials control how surfaces interact with light and thus affect the overall look of your scene. The Node Editor in Octane allows you to create complex materials by connecting various nodes. This provides flexibility for creating layered materials, using masks for blending, and customizing properties extensively.

Textures

Keep texture sizes reasonable to avoid overloading GPU memory. Use appropriate formats (e.g., JPEG, PNG, EXR) based on quality needs. Ensure that texture resolution matches the scale of the object being textured to avoid blurriness.

Octane provides a variety of procedural textures (e.g., noise, wood, marble, gravel) that can create complex patterns without relying on bitmap images. These textures are resolution-independent and can be adjusted at will. Layer multiple procedural textures together to create unique surface variations. For example, you might combine noise patterns for roughness with Voronoi for a pebble effect.

Sampling Settings

• Adaptive Sampling: Enable adaptive sampling to allow Octane to focus samples on areas that need more detail while reducing samples in already clear areas. Adjust the threshold to find the best balance between quality and render time.
• Min/Max Samples: Set appropriate numbers for Minimum and Maximum samples. Start with a lower minimum (e.g., 16) and gradually increase the maximum until you see diminishing returns in quality. For final renders, consider a maximum of 512 samples or higher based on your scene complexity.

Ray Depth

• Max Ray Depth: Adjust the maximum ray depth settings based on your scene requirements. For standard scenes, a maximum specular and transmission depth of 3-5 is often sufficient. This will limit the number of bounces and reduce render calculations.
• Use Global Illumination Sparingly: If GI is not critical for your scene, consider reducing its complexity or turning it off for specific views or objects.

Kernel Type Selection

• Path Tracing vs. Spectral Rendering: For most situations, Path Tracing is sufficient. Spectral rendering will yield better results when dealing with complex materials (like glass), but it can significantly increase render times.
• Use Light Tracing: When there are many light sources in your scene, using Light Tracing can help improve render times while obtaining good quality.

Octane Render is a GPU-based renderer, which means a powerful graphics card (or multiple cards) is essential. High-performance GPUs from NVIDIA (such as the RTX series) are recommended due to their CUDA architecture, which Octane leverages for rendering. Also, you should consider GPUs with ray tracing capabilities (such as NVIDIA’s RTX cards), which can significantly enhance lighting and reflections in your renders.

While Octane primarily relies on the GPU, a capable CPU is still important for tasks such as scene preparation, asset management, and handling non-rendering tasks. Additionally, it is essential to look for a modern multi-core processor to ensure a balanced workflow.

Moreover, having enough system RAM is essential for handling large scenes and multiple applications. Aim for at least 16GB, but 32GB or more is advisable for heavier projects, especially when running additional software alongside Octane (like modeling tools). Faster RAM can improve data access speeds, but the impact might not be as pronounced as in CPU-bound tasks.

We suggest you use SSDs (Solid State Drives) for storing your OS, Octane software, and active project files. SSDs offer significantly faster data access speeds compared to traditional HDDs, which can lead to quicker loading times and improved performance when working with larger assets.

By carefully considering these hardware aspects when setting up your environment for Octane Render, you can significantly enhance your rendering capabilities, minimize frustration, and allow for more complex projects. Investing in the right hardware tailored to your specific needs will pay off through improved performance, efficiency, and overall rendering quality.

In conclusion, working efficiently in Octane requires a blend of technical knowledge and smart workflow habits. By implementing essential tips in Octane—such as optimizing scene geometry, using effective lighting techniques, leveraging render setting, and managing hardware system —you can significantly enhance both speed and output quality. Staying keeping up with updates also ensures you’re getting the best performance from the engine. With practice and these strategies in place, you’ll be well-equipped to harness Octane’s full potential smoothly and effectively.

Unreal Engine’s Niagara system empowers developers with the tools to create stunning particle effects. Lightweight Emitters offer a way to balance visual brilliance with performance efficiency. By optimizing these particle systems, developers can ensure smooth gameplay and high frame rates, making them essential for any project aiming for both beauty and performance.

Let’s explore with iRender!

The Niagara system is Unreal Engine’s next-generation visual effects (VFX) toolset. It allows artists to create complex particle simulations without needing to write code. Niagara is highly adaptable and flexible, enabling technical artists to add custom functionality independently. 

In the Niagara VFX system, there are four core components:

Systems: Niagara systems are containers for multiple emitters, all combined into one effect.

Emitters: Niagara emitters are containers for modules and are designed for single purposes but are re-usable. They allow for creating simulations with the module stack and rendering them in multiple ways within the same emitter.

Modules: Niagara modules are the base level of Niagara VFX. Modules are the equivalent of Cascade’s behaviors. Modules speak to common data, encapsulate behaviors, stack with other modules, and write functions.

Parameters: Parameters are an abstraction of data in a Niagara simulation. Parameter types are assigned to a parameter to define the data that parameter represents. There are four types of parameters: 

• • • Primitive: This type of parameter defines numeric data of varying precision and channel widths.
    • Enum: This type of parameter defines a fixed set of named values, and assumes one of the named values.
    • Struct: This type of parameter defines a combined set of Primitive and Enum types.
    • Data Interfaces: This type of parameter defines functions that provide data from external data sources. This can be data from other parts of UE4, or data from an outside application.

Niagara lightweight emitters, also called stateless emitters, are optimized to minimize (and in some cases eliminate) the use of tick during the simulation. 

In addition, lightweight emitters don’t need to be compiled, which results in a faster workflow and the amount of emitters in a system will have less impact on performance. This means that in most cases a stateless emitter will be significantly more performant than stateful (traditional) emitter.

Stateless emitters were primarily included to lower Niagara’s memory and CPU costs and speed up VFX artists’ workflows. It:

• • • Reduce Game Thread tick cost if the Niagara System is fully stateless.
    • Remove the concurrent tick cost per stateless emitter.
    • Reduce Render Thread cost when the Niagara System is fully stateless.
    • Reduce memory cost, as there are no scripts or particle information in memory.
    • Removes performance impact of emitter count and particle instance count.
    • Reduce (and sometimes remove) the need for compilation.

Step 1: Right-click in the Content Browser, and select Niagara System.

Step 2: In the Asset Browser, select the FountainLightweight system, and click Create.

Step 3: Next open the NS_Fountain_LW system in the Niagara Editor. This system template includes a lightweight emitter for a fountain effect. 

Step 1: Double-click the name of the lightweight emitter to edit the field. Rename the emitter Fountain-LW.

Step 2: Select the emitter, then click Spawn Rate. Change the Rate setting to 300.

Step 3: In the emitter, leave the default settings for the following modules:

• • • Initialize Particle
    • Shape Location
    • Add Velocity
    • Drag
    • Gravity Force

Step 4: Click the Scale Color module. Change the color to red, so you can distinguish more easily between the regular and lightweight systems when testing. Then click OK.

Let’s delve into the distinctions between Rasterization, Ray Tracing, and Path Tracing to see what sets each apart. Understanding the differences between these techniques can help you appreciate how they transform digital models into stunning images

Rasterization is a technique used in computer graphics to convert 3D objects into 2D images. Using rasterization, objects on the screen are formed from a mesh of virtual triangles or polygons that construct 3D models. In this mesh, the corners of each triangle, known as vertices, intersect with vertices from other triangles of various sizes and shapes. Each vertex holds significant information, including its spatial position, color, texture, and “normal” which indicates the orientation of the surface.

Computers then transform these 3D model triangles into pixels on a 2D screen. Each pixel initially receives a color value based on the data from the triangle vertices.

Further processing or “shading” adjusts the pixel color according to how lights in the scene interact with it and applies textures to achieve the final color for each pixel.

• • • Pros 

Rasterization is incredibly fast, making it ideal for real-time applications such as video games and simulations

Suitable for real-time rendering.

• • • Cons

Less accurate in handling lighting, shadows, and reflections. It can result in less realistic images, particularly in scenes with complex lighting.

May require more optimization and manual adjustments to maintain performance.

Ray Tracing is a technique that creates an image by tracing the path of light through pixels on an image plane and simulating its effect when interacting with surrounding virtual objects. Ray means light ray, and Tracing means to track, to chase. In other words, Ray Tracing tracks the light absorbed, reflected, scattered and dispersed by each object in the environment, and it applies not only to a beam of light from the sun but to all different light sources.

For each pixel in the image, ray tracing starts by casting one or more rays from the camera’s viewpoint into the 3D scene. These rays are tracked as they bounce off surfaces (reflection), refract through transparent materials, or get absorbed by objects. The system calculates the color of the pixel based on the ray’s journey when a ray hits a light source or reaches a predetermined bounce limit.

• • • Pros 

Highly realistic images with accurate lighting and shadows. Produces highly realistic images with natural-looking lighting and shadows, enhancing the visual quality of scenes.

Accurately simulates the way light interacts with objects, including reflections, refractions, and shadows.

• • • Cons

It is computationally intensive and slow. It performs slower compared to rasterization, especially in scenes with complex lighting and many light sources.

Requires powerful hardware. Necessitates specialized GPUs with ray tracing capabilities (e.g., NVIDIA RTX series, AMD Radeon RX series) and strong CPUs. Limits accessibility to users with high-end hardware, potentially increasing the cost of entry for advanced graphics rendering.

Path tracing is a complex form of ray tracing, where the GPU calculates the paths of light rays and reflected beams to create more realistic lighting, shadows, and reflections. Path tracing is different from ray tracing, which tracks the path of light rays interacting with the environment in the virtual world. It can create advanced lighting effects but requires a lot of computer resources to execute. Path tracing is widely used in movies, video games, and for 3D rendering.

• • • Pros 

Produces the most realistic images by accurately simulating global illumination.

Handles complex lighting scenarios, including caustics and diffuse interreflection.

• • • Cons 

Very resource-intensive and time-consuming.

Requires significant computational power due to the extensive calculations involved in tracing multiple light paths.

Taking all these points into account, rasterization is equivalent to casting one set of rays from a single point that stops at the first thing they hit. Ray tracing takes this further, casting rays from many points in any direction. Path tracing simulates the true physics of light, which uses ray tracing as one component of a larger light simulation system. 

Rasterization is best for real-time applications where speed is crucial.

Ray Tracing is ideal for high-quality visualizations where accurate lighting and reflections are needed.

Path Tracing excels in producing photorealistic images with complex lighting but is the most computationally demanding.

Ray tracing and path tracing require high-end graphics cards because they involve complex calculations to simulate the behavior of light. Ray tracing traces the path of light rays as they interact with objects in a scene, calculating reflections, refractions, shadows, and more for each pixel. Path tracing, an extension of ray tracing, traces many rays per pixel to simulate light paths more accurately, resulting in even more complex calculations. These processes are computationally intensive and demand significant parallel processing power to achieve real-time performance, which high-end GPUs, like NVIDIA’s RTX series, provide. 

To meet these demanding requirements, iRender is the best choice. iRender offers high-performance GPU servers equipped with the latest NVIDIA RTX graphics cards, providing the necessary computational power for complex tasks like ray tracing and path tracing.

Chaos has released Corona 12 Update 1, the latest version of its production renderer for 3ds Max and Cinema 4D. Let’s explore some important new updates with iRender!

Corona 12 Update 1 introduces an initial implementation of a Live Link. This is just a starting point though, with more functionality to come in future releases.

With this early version, Vantage can be utilized for a form of “Interactive Rendering” that refreshes in real-time as you make adjustments in 3ds Max or Cinema 4D. This detailed ray-traced GPU rendering can be beneficial in certain scenarios while developing your scene. It offers an alternative way to discover ideal camera angles, modify lighting, organize your scene, configure various material aspects, and more.

With this update, you can now send an image directly from the VFB to Chaos Cloud Collaboration, allowing you to share it with your client and engage in discussions using markup and comments. This eliminates the dependence on email, Dropbox, Google Drive, and similar services, plus it means your client isn’t left having to use Paint or Photoshop to draw attention to certain parts of the image.

Cloud Collaboration enables you to create multiple projects and manage their sharing options. It also takes care of image versioning throughout the project and serves as a convenient method for delivering final renders.

To sum up, Cloud Collaboration makes it easy to share images with your clients, sending them right from the VFB. Then, you can discuss changes via markup, send deliverables, set up Virtual Tours, and open the door to much more in the future.

The first improvement to Caustics will now give a significantly cleaner result in the same amount of render time. Can not specify an exact figure for the speed increase since it largely depends on the prevalence of caustics in your scene. If caustics are the primary focus of the scene, you’ll experience a more significant speed improvement compared to a scene where caustics have a minor role.

As an approximation, Caustics themselves should be visually “about twice as good” in the same amount of render time.

The second Caustics improvement allows you to adjust the intensity of the Caustics in the Beauty pass, removing the need to use render elements and post-processing to get the results you are looking for.

Please note that you must set the Surface Multiplier at render time – it cannot be adjusted in post. IR can be used to find the right value before committing to a final render.

The final Caustics improvement is that you now have the option to enable the visibility of reflected or refracted rays created from Caustics as they pass through a Volumetric material.  A common illustration of this is sunlight underwater, where the refraction of light through the shifting water surface creates a captivating display of light beams within the water volume.

Let’s see other cases, such as underwater swimming pool lights passing through steam in a heated pool or jacuzzi, or light beams reflecting off the mirrored surface of a disco/mirror ball through the dry ice in the atmosphere of a night club, or sunlight reflected off windows through an early morning mist and more.

With surface Caustics, you can control the intensity of the volume Caustics in the Beauty pass.

First comes Auto Exposure, a checkbox that lets Corona 12 choose the exposure values for you, just like when using a modern camera. This can serve as a simple starting point, with the option to make additional adjustments through the regular Exposure control or to bake them into the tone mapping.

If “Update during animation” is checked, then the automatic exposure and/or white balance will be recalculated for each frame of an animation, helping with scenes that move from dimly to brightly lit areas.

Additionally, a “Strength” parameter ranges from 0, which means no exposure adjustment, to a maximum of 1, where the calculated auto exposure value is fully applied. This allows for automatic adjustments to exposure or white balance for an effective starting point or to respond to changing lighting during animations. Furthermore, a new algorithm enhances white balance for more pleasing outcomes.

Auto White Balance functions have the same possibilities as mentioned above. There’s one extra improvement to White Balance though, as we have changed the algorithm it uses to one that gives a more natural look. For compatibility, any existing scenes will load with a “Legacy White Balance” to ensure they render the same as before. In new scenes, the new White Balance will be the default. While the difference is subtle, the results are more in line with the effects of White Balance in other popular software like Photoshop.

NVIDIA’s new Image Upscaling offers two key benefits.

First, it enables quick test animations by rendering images at a quarter size (e.g., 960×540 for 1920×1080) and then using AI Upscaler, resulting in a rendering speed that’s approximately four times faster. However, these animations lack temporal consistency, leading to noticeable flickering.

Second, when enabled for Image Refresh (IR), it can improve responsiveness during editing, although parsing times may limit this benefit. It’s particularly useful for scene setup, lighting, and camera angles but less effective for detailed material editing due to reduced detail.

Please note that NVIDIA Denoising is always applied to the image when Upscaling is used, both in IR and rendering modes. Also, just like NVIDIA Denoising, this requires a compatible NVIDIA card.

iRender provides high-performance and configurable server systems to customers who need to utilize the power of CPU & GPU such as 3D rendering, AI training, VR&AR, simulation, etc. With iRender IaaS and PaaS services, you can access our server through the Remote Desktop Application do whatever you want, and install any software you need on it. It is like you are using your own computer but with a powerful configuration and much higher performance. In particular, you only need to install the software for the first time, the next time you connect to the computer everything is ready for you to use.

Corona Renderer is purely CPU-based. It uses Intel Embree Ray Tracing Kernels, the fastest CPU ray tracing solution on the market. Since they mesh well with the Corona architecture, they are an important factor in its performance.

By rendering only on the CPU, we can avoid all bottlenecks, problems, and limitations of GPU rendering, which include the unsuitability of GPU architectures for full GI, limited memory, limited support for third-party plugins and maps, unpredictability, the need for specialist knowledge or hardware to add nodes, high cost, high heat and noise.

Also, Corona usually comes with Cinema 4D and 3ds Max. We support all 3D software including Cinema 4D and 3ds Max with their plug-ins. Moreover, we have preinstalled Cinema 4D and you can use a free Cinema 4D license from us. With Corona, you can consider our 3S server.

Now we have a huge promotion for the biggest sale event of the year: Black Friday. Don’t miss this best deal and speed up your rendering performance with iRender.

Eevee Next, called Eevee in Blender 4.2, improves the visual quality of renders generated with Eevee: both viewport renders, and when using it as an alternative to Cycles for final-quality output. The Eevee render engine was rewritten to allow deeper changes, removing long-standing limitations and facilitating future evolution. In this article, let’s delve into new features in Eevee Next with iRender! 

Eevee now uses screen space ray tracing for every BSDF. There is no longer any limitation to the number of BSDFs.

It simulates how light bounces off surfaces and interacts with other objects in the scene, creating more realistic lighting. This means that light can now reflect off walls, floors, and other objects, illuminating areas that would otherwise be in shadow. This feature significantly enhances the realism of indoor scenes and complex environments.

Previously, within Blender’s Eevee render engine, there existed a restriction of 128 active lights within a scene. Nevertheless, with the introduction of Eevee Next in Blender 4.2, this limitation has been removed. You can now add as many lights as you need, which is particularly useful for complex scenes that require detailed lighting setups. This allows for more creative freedom and the ability to create more dynamic and visually interesting scenes. However, only 4096 lights can be visible at the same time.

In addition, Lights in Eevee Next now support ray visibility options and Glossy lighting no longer leaks at the back of objects.

Lights are now visible through refractive surfaces. A new transmission influence factor has been added and set to 0 for older files.

The new shadow system in Eevee Next is designed to be more stable and produce higher-quality shadows. Shadows are now rendered using a technique called  Virtual Shadow Maps which reduces shadow artifacts and provides smoother transitions between light and shadow. This greatly increases the maximum resolution, reduces biases and simplifies the setup. 

 This system is also more memory efficient, allowing for better performance even in scenes with many light sources. 

• • • The calculation of light visibility now utilizes Shadow Map Ray Tracing, producing realistic soft shadows without the requirement for shadow jittering. 
    • Shadow Map biases have been eliminated and are now automatically calculated. There are plans to address the shadow terminator issue in upcoming releases. 
    • Contact shadows have been taken out as Virtual Shadow Maps are typically accurate enough. 
    • Shadow clip start has been eliminated and substituted with an automatic value.

The transparency settings in Eevee Next have been upgraded, making it easier to create realistic glass and other transparent materials. This includes better handling of refractions and reflections, providing more accurate and visually appealing results

Displacement is now supported with the exception of the Displacement Only mode which falls back to Displacement And Bump. Three displacement methods exist, with varying accuracy, performance, and memory usage. The displacement method can be set per material in the Material Settings.

A new Thickness output has been introduced. This allows better modeling of Refraction, Subsurface Scattering and Translucency. Some materials might need adjustment to keep the same appearance. This replaces the former Refraction Depth option.

Volume rendering has been significantly improved in Eevee Next. This includes better handling of smoke, fog, and other volumetric effects. The new system provides a more accurate and realistic rendering of these effects, making it easier to create atmospheric scenes. The improvements also include better performance, so you can work with volumetric effects without a significant impact on rendering times.

World volumes are no longer limited to clipping distance, which means they can completely block sunlight and the world background. Older files can be converted using the conversion operator in the Help menu or in the World > Volume panel. 

• • • Volume lighting is now dithered to avoid flickering.
    • EEVEE now maximizes the depth range automatically if no world is present.
    • Mesh objects now have correct volume intersection instead of rendering bounding boxes.
    • The evaluation of many small-volume objects has been optimized.

Eevee’s old versions supported these effects but with limitations in quality and performance. Motion blur and depth of field could appear less realistic.

In this new release, Motion blur and depth of field effects have been enhanced to provide more realistic results. Motion blur simulates the blurring of moving objects, which is crucial for creating realistic animations. Depth of field simulates the focus effects of a camera lens, allowing you to blur out-of-focus areas of your scene. These improvements help in achieving a more cinematic look and feel in your renders.

• • • Screen Space Reflections (SSR): Improved SSR for more accurate reflections on surfaces.
    • Subsurface Scattering (SSS): Enhanced SSS for better rendering of materials like skin, wax, and other translucent materials.
    • Performance Optimizations: Various optimizations to improve the overall performance of EEVEE, making it faster and more efficient.

Eevee Next in Blender 4.2 LTS brings substantial improvements in lighting, shadows, shading, volume rendering, and overall performance. These enhancements make it a more powerful and versatile tool for real-time rendering, providing high-quality visuals and improved efficiency. Whether you’re working on animations, visual effects, or architectural visualizations, Eevee Next offers the tools and performance needed to create stunning, realistic scenes.
