• Camera
  • Added support for negative clipping planes ( useful on ortho cams )

IECoreHoudini

• Fixed CurvesPrimitive duplication in Houdini SceneCacheSource SOP

Version 9.12.0

IECoreArnold

• Added read/write access concept to UniverseBlock (#514).
• Added automatic loading of metadata files to UniverseBlock (#514).

  variables which clash with built in parameters are ignored instead (#519).
• Added support for GeometricTypedData interpretation in primitive variables (#519).
• Support setting enum parameters using integer index

IECoreMaya

• LiveScene
  • Added support for multiple shapes under a transform, by merging them
    into a single Cortex object (#516).
