Welcome to RenderMan 23.1. This release introduces improvements to the previous RenderMan in very significant ways.
Please dive right into the release notes below for more detailed information on the latest version of your favorite renderer!
PxrSurface has a new parameter "float glassRefractionRoughness". If specified, this roughness is used for glass refraction while the regular "glassRoughness" is used for reflections. If not specified, the regular "glassRoughness" is used for both reflection and refraction, this is not layerable in this version
Fixed a bug when installation paths with '#' in them would cause "it" to not start and print an error message
Fixed incorrect adaptive sampling when relativepixelvariance was not specified
Fix RixProjectionEnvironment::worldToCameraMatrix when using option trace:worldorigin of camera. This fixes PxrCamera's tilt shift feature
A bug where RixShadingPlugin::SynchronizeInstanceData() would not be called for displacement shading networks has been fixed
A bug which affected semi-sharp subdivision mesh creases with a non-integer value has been fixed
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.
