This release introduces improvements to RenderMan.
Please dive right into the release notes below for more detailed information on the latest version of your favorite renderer!
There are two new optional controls for path-traced subsurface scattering - Attribute "trace" "int sssautobias" and "trace" "float sssbias". In the rare cases where the automatically computed bias for
path-traced subsurface scattering needs tweaking, one can set "sssautobias" to 0 and "sssbias" to a desired value such as 1e-6. The default values are 1 for "sssautobias" and 1e-4 for "sssbias".
Fix for bugs batched trace() with multiple shader groups in the hits.
