Blender Cycles X: How to Get the Experimental Build and What to Expect



Download Blender Cycles X: A Faster and More Interactive Rendering Engine




If you are a Blender user, you probably know that Blender has two main rendering engines: Eevee and Cycles. Eevee is a real-time engine that uses rasterization techniques to produce fast and realistic results. Cycles is a physically-based, ray-tracing engine that uses path tracing to produce high-quality and photo-realistic results.


However, you may not know that there is a third option available for you to try: Blender Cycles X. This is a research project that aims to refresh the architecture of Cycles and prepare it for the next 10 years. It was announced in April 2021 by Brecht Van Lommel, one of the main developers of Cycles, to celebrate its 10th anniversary.

Blender Cycles X is not an official release yet, but it is available as an experimental build that you can download and test. It promises to improve the performance, usability, and features of Cycles rendering engine. In this article, we will show you how to download, install, and use Blender Cycles X, as well as what are its main features and benefits. We will also show you how to compare it with Blender Cycles and see the difference for yourself.


How to Download and Install Blender Cycles X




Downloading and installing Blender Cycles X is very easy. You just need to follow these steps:


  • Go to the and find the Cycles X branch. This is where you can find all the experimental builds of Blender that have new features that may end up in official releases.



  • Choose your operating system (Windows, MacOS, or Linux) and download the zip file. The file size is about 200 MB.



  • Extract the zip file to a folder of your choice. You don't need to install anything, just run the blender.exe file inside the folder.



Congratulations, you have successfully downloaded and installed Blender Cycles X. Now you can start using it for rendering.

  • Switch to the Cycles render engine in the Render Properties panel. You can choose between CPU or GPU rendering, depending on your hardware.



  • Adjust the render settings according to your needs. You can change the sampling, light paths, denoising, color management, film, performance, and output settings as usual.



  • Start the viewport or final render and enjoy the speed and interactivity of Blender Cycles X.



That's it. You have successfully used Blender Cycles X for rendering. You should notice a significant improvement in the render time and quality compared to Blender Cycles.


What are the Main Features and Benefits of Blender Cycles X




Blender Cycles X is not just a faster version of Blender Cycles. It also has some new features and benefits that make it more attractive and powerful. Here are some of them:


  • New GPU kernels: Blender Cycles X has new GPU kernels that are optimized for modern hardware, such as NVIDIA RTX and AMD RDNA cards. These kernels use ray tracing acceleration structures, such as BVH and OptiX, to speed up the rendering process. They also support more features, such as motion blur, depth of field, and subsurface scattering.



  • Improved viewport rendering: Blender Cycles X has improved viewport rendering with adaptive sampling and batching samples. This means that it can adjust the number of samples per pixel based on the noise level and the complexity of the scene. It can also group multiple samples together and send them to the GPU in one batch, reducing the overhead and latency. This results in a smoother and more responsive viewport experience.



  • More advanced rendering algorithms: Blender Cycles X has more advanced rendering algorithms for volume, hair, shadow, and noise reduction. For example, it has a new volume rendering algorithm that can handle multiple scattering and absorption more accurately and efficiently. It also has a new hair rendering algorithm that can produce realistic hair shading and highlights. It also has a new shadow catcher feature that can create realistic shadows on transparent backgrounds. It also has a new denoising feature that can reduce noise without losing details.



These are just some of the main features and benefits of Blender Cycles X. There are more to come as the project evolves and matures.


How to Compare Blender Cycles X with Blender Cycles




If you want to see how Blender Cycles X compares with Blender Cycles, you can use one of these methods:


  • Use the same scene and render settings: You can use the same scene and render settings in both Blender Cycles X and Blender Cycles and measure the render time and quality. You can use a stopwatch or a timer to measure the render time, and you can use a tool like to compare the render quality.



  • Use benchmark scenes: You can use benchmark scenes from the . These scenes are designed to test the performance and features of different rendering engines. You can download them and render them in both Blender Cycles X and Blender Cycles and compare the results.



Either way, you should see a noticeable difference between Blender Cycles X and Blender Cycles in terms of speed and quality.
