[johnhaddon]

Features

• CopyObject : Added new node for copying objects from one scene to another.

Improvements

• PrimitiveQuery : Added primitive output ¹.
• StandardAttributes :
  • Added linkedLights:exclusions and shadowedLights:exclusions attributes, specifying lights that never illuminate or cast shadows from an object.
  • Added filteredLights:exclusions attribute, specifying lights that are never filtered by a light filter.
  • Moved filteredLights and filteredLights:exclusions to a new "Light Filters" section in the NodeEditor and AttributeEditor.
• LightFilter, ArnoldLightFilter, RenderManLightFilter : Added filteredLightsExclusions plug.
• SceneWriter : Defaulted to writing RenderMan attributes in a format compatible with hdPrman, for rendering 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 ².

Documentation

• Light Linking : Updated to describe use of the linkedLights:exclusions attribute.

Breaking Changes

• SceneWriter : Changed writing of ri: prefixed attributes to USD. Set IECOREUSD_WRITE_CONFORMANT_RENDERMAN_ATTRIBUTES=0 to revert to the default behaviour from Gaffer 1.6.
