Images that we couldn’t actually render to full convergence, now were renderable because we could run the denoiser. That allowed us to render images with fewer samples, which was faster, but also let us render more complexity. That cut our render times down quite substantially. “There,” says Sisson, “instead of sending maybe 2,000 samples or 4,000 average samples per pixel, we were able to render with something like 512 average samples per pixel, a big savings at the time. Pixar, of course, comes under the same technology umbrella as Walt Disney Animation Studios, and was able to use this previous denoiser first on Finding Dory (2016). The last couple iterations to achieve full convergence can take as long as the rest of the render simply because the amount of samples required for each iteration grows exponentially.”įor that original denoising tech, Pixar utilized a denoiser that Walt Disney Animation Studios had developed for its Hyperion path tracer on Big Hero 6. “Every time you iterate on the image or the render iterates, it starts to converge. “Path tracers are inherently noisy,” notes Pixar marketing manager Dylan Sisson. Read all about the new features in version 25 in the Release Notes.Pixar originally adopted denoising technology once it had rolled out its original RIS path tracer several years ago. Lookdev improvements in RenderMan XPU™ - These features make XPU renders an even closer match to RIS on a broader variety of look development scenarios by providing support for features such as LPEs and trace groups.Įnhanced Cameras in RenderMan XPU™ - Use interactive rendering for dialing in the depth of field, vignetting, and other camera effects. Stylized Looks improvements - RenderMan’s toolset for generating non-photorealistic images receives various updates, including numerous enhancements to give artists more control over Toon shading, Illustrative lighting through hatching & watercolor, and Linework. RenderMan 25 brings improvements in how light interacts between material layers, as well as new iridescence material response. First introduced in RenderMan 24, MaterialX Lama brings users a component-based and physically plausible shading system for "Layered Materials". MaterialX Lama improvements - Our partnership with Industrial Light & Magic continues with RenderMan 25. The denoiser will allow you to cut off your renders substantially earlier than before, saving you time on your render farm. It maintains sharpness even in the most difficult of scenes, such as those with hair and fur, or those with lots of points-based effects. RenderMan 25 - Main Featuresĭenoiser - Originally developed at Disney Research, in conjunction with Pixar, Walt Disney Animation Studios, and Industrial Light & Magic, the new Denoiser brings machine learning to denoising. RenderMan XPU ™ brings support for LPEs and a new texture cache that provides faster render times on machines low on GPU memory. RenderMan version 25 provides a next-level denoiser that allows you to substantially reduce render times, new MaterialX Lama features from ILM, and new features in Stylized Looks. Pixar's RenderManįor over 30 years RenderMan has been at the forefront of the visual effects revolution, and today RenderMan is a high-performance renderer built to tackle the most complicated 3D scenes imaginable. Here you can find information on how to install, license, and use RenderMan and its various bridge products for Maya, Houdini, Blender, and Katana. Welcome to the RenderMan 25 Documentation!
