Welcome to RenderMan for Maya (RfM) 21.2!

Welcome to RfM 21.2 This release introduces improvements and some fixes to the previous release.

New Features:

• The RenderMan preferences now include a preference for the number of prman threads to use for swatch renders.

Miscellaneous Changes

• When 'it' opens a file with a large ply, the channels are split into a main image and AOVs as sub-elements under that. 'it' looks for R, G, B & A for the main image and groups the remaining channels by name into each AOV.
• The list of optional attrs now includes the new Prman attributes: reflectexcludesubset, shadowexcludesubset, transmitexcludesubet.
• Maya File (texture) pattern now defaults lerp to ON
• The Preset Browser has been improved to work with more types of shader networks.

Bug Fixes

• Fixed a bug which could lead to Maya hanging, for example, if 'it' was launched from the shelf while swatch renders were underway.
• Maya's volumeFog shader is now translated correctly as a PxrVolume.
• Fixed a bug that prevented the RenderMan Attributes Window from opening in Maya 2015.
• Fixed a bug where attrs of PxrSurface that were driven by Maya expressions weren't updating during batch renders.
• Fixed a bug where animated parameters on pattern nodes failed to update properly when Maya's Evaluation Mode preference was set to Parallel.
• Fixed a bug where imagePlane nodes would still render when the Display Mode was set to None. Now this works as expected.
• Fixed a bug where referenced maya scenes containing PxrLayer nodes would cause warnings and fail to render correctly.

• LocalQueue would not run on macOS if there was a local install of Qt4

• A number of AOV bugs related to renaming and LPEs were fixed in RfM.
• Preset Browser: materials using PxrLayerSurface were rendering grey.
• Preset Browser: float to manifold conversions were not correctly handled.
• Preset Browser: Maya's ramp node wasn't correctly parsed.
