TDs get a user-customisable new Live Statistics system, which displays memory usage, rays traced and other key metrics in real time during render sessions. New live statistics system for TDs, support for blue noise sampling In addition, a new Bump Roughness system helps to preserve micro-details of surfaces, traditionaly lost in medium and wide shots, when the surface is some distance from the render camera.

There is also a new Bump Mixer, which replaces the old bump map handling system, and is described by ILM as meaning that users “don’t have to execute bump code three times”. New patterns available included Phasor Noise, developed at ILM during production on Star Wars: The Rise of Skywalker, and Hex Tiling, intended to blend tiled textures seamlessly. RenderMan’s existing library of procedurally generated material Patterns has been rewritten to fully support OSL (Open Shading Language).Įxecution is accelerated on both Intel and AMD CPUs vai the SIMD AVX-512 extensions. New Phasor Noise, Hex Tiling and Bump Mixer patterns In addition, the Preset Browser has been updated to save Lama materials and display filters, making it possible to share them between RenderMan-compatible DCC applications. Users can write their own custom nodes, but Pixar says that even out of the box, Lama can replicate most of the existing “monolithic” BxDFs included in the software. Other key features include LamaHairChiang, a layerable version of the Pixar Chiang hair shader used in production at Pixar, and support for dispersion: a common request among RenderMan users. They include BxDFs for dielectric and conductor materials, and a Lama version of the old PxrDisney shader with support for subsurface scattering.

Instead, Lama enables shading TDs to build up layered materials via a modular workflow, wiring together a series of BxDF (Bidirectional Distribution Function) nodes developed by ILM. Pixar described it as a “much more robust layering system” than the existing PxrLayerSurface material, avoiding the need to use a single material with a “ton of parameters”. RenderMan 24 will also feature Lama, a new layered materials system developed at Industrial Light & Magic, and and an “official part” of the ILM-developed MaterialX standard. Lama: a robust new modular system for layered materials developed at ILM However, the toolset will only be available to users of the commercial edition of the software: something Pixar attributed to the work being a partnership with third-party developer LollipopShaders. Pixar describes it as “super-customisable”, noting that work “usually done in comp” to stylise an image can now be performed directly during rendering. It is capable of effects ranging from conventional cartoon shading to hatching or brush strokes, with the hatching reacting to emulated light effects, and supports custom AOVs and display filters. Stylized Looks generate anything from toon shading to brush stroke effectsīeginning with the feature that has been most widely previewed already, RenderMan 24 will support Stylized Looks, a new toolset for generating non-photorealistic renders. Pixar has also confirmed that RenderMan XPU, its long-awaited new combined CPU and GPU rendering system, will form part of the release, as will a new official integration plugin for Blender. The release, which is due to ship early next year, will include several important new toolsets, including a new sylised rendering system, and Lama, a new layered material system developed at ILM.

Pixar has unveiled RenderMan 24, the next major update to the VFX and animation production renderer, during livestreams at this week’s RenderMan Art & Science Fair. Scroll down to the end for details of features announced since the original preview. We have updated the story with extra information from the release notes.
