![]() ![]() ![]() Reyes rendering and RSL ditched in favour of newer technologies ![]() The entire lighting system has also been “completely rewritten” to improve performance, with the online documentation promising that “scenes with over one million lights render more quickly and easily”.Īccording to Pixar, the changes make the software “increasingly more than a renderer: RenderMan is a complete shading and lighting ecosystem”. In addition, RenderMan 21 includes an extended set of light types, plus a set of light filters to modify their behaviour, developed for use in Pixar productions. The renderer gets a new PxrDirt pattern for reproducing dirt and weathering effects along with new options for baking patterns as 2D maps, Ptex images or point clouds for reuse on other assets. The update also extends the Patterns system, used to vary parameters across the surface of a material. RenderMan 21 also ships with the Pixar Surface Collection (image below): a library of presets for PxrSurface, designed to replicate common materials inluding “plastics, metals, ceramics, rocks, liquids and more”. It seems to replace several older shaders like PxrDisney and PxrGlass: the online documentation now lists only PxrSurface and existing hair and volumetric shaders PxrMarschner and PxrVolume. The key addition is PxrSurface, a versatile new multi-purpose surface shader capable of reproducing anything from glass to skin. New PxrSurface material, used in-house at Pixarįirst of all, the update makes the shaders used in production at Pixar itself available out of the box. While the reasoning wasn’t fully apparent at the time – the features announced early, like GPU support for Denoise, seemed more like evolution than revolution – it has become clearer with the final release. The update was originally previewed in Pixar’s community newsletter earlier this year, which described it as a “game-changer and the biggest RenderMan release in years”. The update also adds GPU support for the software’s Denoise system and removes several legacy technologies – including the venerable old Reyes rendering system. Pixar has released RenderMan 21, the latest update to its heavyweight production renderer, incorporating the same shaders and lights used in production at Pixar, and adding a new library of PBR materials. Hank from Finding Dory: one of the characters rendered in production by Pixar using its versatile multipurpose PxrSurface shader – now implemented in RenderMan 21, released commercially this week. ![]()
