Stylized Looks: new Distort option for line rendering In addition, Lama now more accurately replicates the way that light interacts between material layers. The release also features updates to the major toolsets added in RenderMan 24, including MaterialX Lama, the Industrial Light & Magic-developed MaterialX-based material layering system.Ĭhanges in RenderMan 25 include a new material response for iridescent materials, LamaIrisescence, which includes the option to map the colours generated to an artist-directed colour set. We covered the architecture of the new denoiser, which is integrated into RIS, RenderMan’s CPU-based final-quality render engine, when Pixar previewed it last year, so check out this story for more information. It is tailored to both photorealistic VFX and stylised animation, having been trained using production data from ILM, Pixar and Walt Disney Animation Studios, and is designed to preserve complex details in shots.Īccording to Pixar, it “excels on complex, detailed imagery that would cause other denoisers to fail”, such as shots containing a lot of hair and fur, or FX shots with complex points-based effects. New AI-based denoiser trained on VFX and animation data sets from ILM, Pixar and DisneyĪlthough RenderMan 25 isn’t as large an update as 2021’s milestone RenderMan 24, it has its own major new feature, in the shape of the AI denoiser used on every Pixar movie since Toy Story 4. The integration plugins for Blender, Houdini, Katana and Maya have all also been updated. RenderMan XPU, Pixar’s hybrid CPU/GPU render engine, gets a significant update, adding support for volumes and deformation motion blur, and can now be used for a wider range of lookdev work. Key changes include the integration of the AI-trained denoiser used by Pixar on its own animated features, and updates to the MaterialX Lama layered material system and Stylized Looks toolset. Pixar has released RenderMan 25.0, the next major update to the VFX and animation production renderer.
