![]() Volumes: A significant bug in minlength dicing causing artifacts in XPU volumes when using dsominmax 0 has been addressed.LPEs and AOVs: Indirect LPEs in XPU now match RIS better for the case of surfaces with multiple lobes and high specular roughness.This only has an effect if pathguiding is enabled, and provides significant convergence improvements in a number of cases, particularly for surfaces with lower roughness. Integration: Switched from MIS to Resampled Importance Sampling for weighting pathguiding and BxDF samples.Baking: Fixed a crash that could result when baking UDIMs for materials using Lama networks.Volumes: Fixed a memory leak in PxrPathTracer when aggregate volumes were used.BxDFs: Lama albedo AOVs should now correctly take tint parameters into account.The artifacts are only visible when the parameter "adjustAmount" in PxrBump is different to its default value of 1.0. BxDFs: Fixes some of the artifacts in Lama when low poly meshes are used in addition to bump maps.This was an issue on high core count machines. Decrease the number of threads that the statistics framework spawns.Upgraded the compiler we use to build RenderMan to solve an issue that could cause spurious crashes.Please see the RenderMan 25.0 Release Notes for all of the new features and known limitations of RenderMan 25. This release provides you with bug fixes and minor enhancements. RenderMan 25 brings many tools that improve artist workflows and complement the creative process. RenderMan version 25.2 builds on RenderMan 25.0 and 25.1, which provided major upgrades to look development and batch rendering. ![]() Elemental © Disney/Pixar JWelcome to RenderMan 25.2
