Pixar's RenderMan 26 Introduces Interactive Machine Learning Denoising

Pixar Animation Studio has released RenderMan version 26, calling it a significant advancement in Pixar's rendering technology. While the key highlight is the introduction of an interactive version of machine learning Denoiser, there are plenty of smaller rendering performance updates including faster instancing and texture read parallelism as well as RenderMan's Stylized Looks now delivering enhanced creative control and a more intuitive user experience.

Thanks to machine learning, the Denoiser is so accurate, that it significantly reduces rendering times while maintaining high fidelity, and "has been occasionally called 'magic' by industry veterans". It's perfect for demanding applications like animation and VFX since it manages to preserve all the intricate details.

Interactive Denoiser is capable of removing noise on images with very low average sample counts and is predictive of the full offline Denoiser, which revolutionizes rendering workflow and reduces iteration times.

RenderMan XPU hybrid renderer has received major updates, enhancing light support, camera controls, and adaptive sampling capabilities, accelerating rendering and interactivity. 

Both XPU and RIS received greatly improved performance when creating and editing scenes with many instances and textures. The updated Stylized Looks toolset gives artists new ways to express line work and toon effects.

Lastly, RenderMan 26 has expanded XPU support for Pixar camera features, received USD advancements, and more.
