Breaking Changes

• OpenImageIO : Updated required version to 2.3 (#1246, #1230).
• Alembic : Dropped support for Alembic versions prior to 1.6 (#1240).
• IECoreGL : Removed PerspectiveCamera.h header. The implementation was already removed in a Cortex 10.1.0.0 (#1241).

Cortex 10.3.3.0

• IECoreGL
  • Shader : Added support for 1D samplers (#1243).
  • CurvesPrimitive : Added limited support for point drawing mode (#1247).

Cortex 10.3.2.1

Fixes

• USDScene :
  • Fixed reading of Houdini's paired representation of primvars with varying-length arrays per vertex/face (#1233).
  • Fixed reading of custom attributes without an authored value. These are now ignored by attributesNames() (#1234).

CI

• Windows : Added testing of IECoreUSD (#1233).

Cortex 10.3.2.0

Improvements

• ShaderNetwork : Added _copy argument to getShader() binding (#1228).
• ShaderNetworkAlgo : Added addComponentConnectionAdapters() and
  removeComponentConnectionAdapters() (#1228).

Fixes

• USD :
  • Fixed export of shading networks containing component-level connections (#1228).
  • Fixed compilation with USD 20.08 (#1226).

Build

• Windows :
  • Defaulted to O2 optimisation level (previously Ox) (#1224).
  • Added RenderMan display driver to build (#1225).
• CI : Updated to GafferHQ/dependencies 4.0.0 (#1227).

Cortex 10.3.1.0

Features

• USDScene (#1214) :
  • Added support for reading and writing IECoreScene::ShaderNetwork attributes via USDShade.
  • Added initial support for writing Arnold globals.
• ShaderNetworkAlgo : Added expand/collapseSplineParameters() functions (#1218).

Improvements

• Windows :
  • Added IECoreGL support (#1211).
  • Added IECoreUSD support (#1204).
  • Fixed many build warnings (#1217).
• SceneInterface : Improved error messages for unrecognised file extensions (#1214).

Fixes

• FromHoudiniPolygonsConverter : Fixed bug whereby a mixture of open and closed polygons were converted as a single MeshPrimitive. We consider open polygons to be linear CurvesPrimitives, so they should not be convertable as MeshPrimitives (#1212).
• CurvesPrimitiveEvaluator : Fixed C++17 compilation error (#1216).
• SceneCacheFileFormat : Stopped labelling primvars as custom (#1214).

Cortex 10.2.3.1

Fixes

• FromHoudiniPolygonsConverter : Fixed bug whereby a mixture of open and closed polygons were converted as a single MeshPrimitive. We consider open polygons to be linear CurvesPrimitives, so they should not be convertable as MeshPrimitives (#1212).

Cortex 10.3.0.0

Improvements

• LinkedScene : Path element separators (forward and backslash) are now platform independent (#1193).
  • Paths are internally stored using forward slash only.
  • Paths are returned by readAttribute in OS-native format.
• IECoreGL : The render:displayColor attribute is now passed to the Cs parameter of GLSL shaders (#1209).
• IECoreUSD : Added round-tripping of constant USD primvars through Cortex as attributes with a render: prefix (#1188).

Fixes

• StreamIndexedIO : Fixed memory leak when passing NullIfMissing or ThrowIfMissing to directory() (#1181).
• Build : Fixed build error when running scons via Python 3 (#1184).
• TBB : Reduced reliance on deprecated TBB features (#1194).
• IECoreScene tests : Added missing tests for SceneInterface, TransferSmoothSkinningWeightsOp and TypedPrimitiveOp (#1193).

Breaking Changes

• IECoreArnold : Removed. This is now maintained as part of GafferHQ/gaffer (#1199).
• HeaderGenerator : machineName, systemRelease, systemVersion, may differ from previous versions on Windows. Linux and MacOS are unaffected.
• HeaderGenerator : nodeName is no longer converted to all capital letters and may differ from previous versions on Windows. Linux and MacOS are unaffected.

CI

• Windows : Added testing of IECoreImage, IECoreScene, IECoreAlembic and IECoreVDB (#1183, #1193, #1205, #1206).
• Migrated build container hosting to the GitHub Container Registry (#1200).

Cortex 10.2.3.0

Improvements

• IECoreUSD SceneCacheFileFormat : Added support for per frame writing (#1178).
  • This can be used in conjunction with Houdini Solaris "flush after each frame" write mode.
