Welcome to RenderMan 22.7. This release introduces improvements to the previous RenderMan.
Please dive right into the release notes below for more detailed information on the latest version of your favorite renderer!
Spherical RiPoints using pointfalloff now have better lighting behavior when it comes to interpenetrating spheres. The calculation when the ray origin is inside a sphere has been amended to provide a more predictable lighting result
PxrUnified now supports Attribute "trace" "diffusedepth" and "speculardepth". Unlike PxrPathTracer, this behavior is opt-in only and must be enabled by setting the new integrator parameter "useTraceDepth" to 1
Fixed an intermittent crash when linear curves which had varying opacity were used
Fixed a potential crash when geometry deformation sample times are different from the shutter time
Fixed UDIMs with extra filepath separators
A bug that caused EXR displays that were dirmapped to fail to render has been addressed
Fixed a rare bug where the renderer could crash during expansion of procedurals if the procedural had an invalid transformation matrix
Fixed a rare memory corruption when freeing geometry buffers. The corruption was manifesting as a crash during rendering startup or at completion
Fixed a regression that prevented projection plug-ins from accessing textures at CreateInstanceData time
Fix an issue with INFs (infinite or not a number) appearing in deep output of volumes
OSL will no longer complain about missing coordinate systems in the log, you must now check your return values in shaders instead
Deformation motion blurred volumes don't currently work with densityFloatPrimVar or densityColorPrimVar. You will need to use a PxrPrimVar node connected to densityFloat and densityColor instead
The Centos KDE style "Oxygen" installs a version of Qt and sets the user's environment variable QT_PLUGIN_PATH forcing "it" and LocalQueue to attempt to load an incompatible Qt library. Either avoid installing the Oxygen theme or unset QT_PLUGIN_PATH before running "it" or LocalQueue. Other KDE styles may also install this theme.
