1.6.21.0

Improvements

• SceneWriter : Added IECOREUSD_WRITE_CONFORMANT_RENDERMAN_ATTRIBUTES environment variable. When set to a value of 1, ri: prefixed attributes are written to USD in a format compatible with hdPrman, for rendering with RenderMan in usdview and other Hydra-based applications.

Fixes

• RenderMan : Fixed handling of V3f data with non-geometric interpretation. Common sources include float3 primvars and attributes loaded from USD files.

Build

• Cortex : Updated to version 10.6.7.0.
