Cortex 10.4.10.3

Fixes

• USDScene : Fixed treatment of unconnected material outputs during reading. If they were "authored" but not connected to a source, they were incorrectly being treated as valid attributes, and loading as empty ShaderNetworks which caused problems elsewhere.

Cortex 10.5.1.0

Improvements

• USDScene : Added limited support for reading and writing Volume prims via IECoreVDB::VDBObject.

Fixes

• USDScene : Fixed writing of lights so they are represented as appropriate UsdLux*Light prims in USD.
• FrameRange : Prevented creation of FrameRanges with negative steps
• IECore.dataTypeFromElement : Fixed support for list to Vector conversions
• LinkedScene : Fixed bug where linkLocations attribute was baked incorrectly if the link target location wasn't the ROOT
  • This in turn caused LinkedScene::setNames() and LinkedScene::readSet() to error
• IECoreNuke::FromNukePointsConverter : Use Color3f instead of Color4f to be compatible with Gaffer
• IECoreNuke::SceneCacheReader : Fixed crash with SceneCacheReader when widget updates while Caribou updates

Cortex 10.4.10.2

Fixes

• LinkedScene : Fixed bug where linkLocations attribute was baked incorrectly if the link target location wasn't the ROOT
  • This in turn caused LinkedScene::setNames() and LinkedScene::readSet() to error
• IECoreNuke::FromNukePointsConverter : Use Color3f instead of Color4f to be compatible with Gaffer
• IECoreNuke::SceneCacheReader : Fixed crash with SceneCacheReader when widget updates while Caribou updates

Cortex 10.4.10.1

Fixes

• FrameRange : Prevented creation of FrameRanges with negative steps
• IECore.dataTypeFromElement : Fixed support for list to Vector conversions

Cortex 10.5.0.0

Features

• MeshAlgo :
  • Added new algorithms for computing mesh normals : calculateUniformNormals(), calculateVertexNormals() and calculateFaceVaryingNormals().
  • Added correspondingFaceVertices() method.

Improvements

• MeshAlgo distributePoints() :
  • Added support for density primitive variable values above 1.
  • Added sampling of arbitrary primitive variables via the new primitiveVariables parameter.
  • Improved accuracy.
  • Improved performance.
• MeshAlgo triangulate() : Improved performance.
• MeshAlgo connectedVertices() : Improved performance.

Fixes

• MeshAlgo distributePoints() :
  • Fixed duplicate points at triangle edges.
  • Fixed handling of points exactly at the density threshold.
• TriangleAlgo :
  • triangleClosestBarycentric() : Fixed numerical precision bug.
  • triangleContainsPoint() : Fixed handling of zero-area triangles.
• PolygonVertexIterator : Fixed to use std::iterator_traits so that raw pointers are supported.

Breaking Changes

• IECoreAppleseed : Removed. With Appleseed's removal from Gaffer 1.3.0.0 Cortex no longer provides IECoreAppleseed.
• Python : Removed support for Python 2.
• Primitive : Changed variableIndexedView() return type from boost::optional to std::optional.
• MeshAlgo distributePoints() :
  • Changed function signature.
  • Bug fixes mean subtle changes to the resulting points.

Cortex 10.4.10.0

Improvements

• IECoreNuke::LiveScene :
  • Adding caching to speed up querying Nuke's GeometryList for large hierarchy
  • Support for ParticleSprite
  • setOp method to avoid re creating LiveScene from scratch

Fixes

• IECoreMaya.SceneShape : Fixed reading of time samples for expanded link locations
  • Traverse the time plug connections to check for a maya global time connection
• CheckedGILRelease : Safe to call if thread doesn't hold the GIL
• IECoreNuke::SceneCacheReader : release GIL during _validate to avoid crash with Caribou
• IECoreNuke::LiveScene :
  • Fix crash when there is not input GeoOp.
  • Fix uninitialized bounds
  • Fix bug with duplicated parents
  • Fix bug when querying children combined between multiple parents

Cortex 10.4.9.1

Fixes

• USDScene : Fixed hash clashes when the same USD file containing instanceable prims was opened a second time. Because USD doesn't assign prototypes deterministically, hashes would be shuffled between prototypes, yielding inconsistencies between the hashes for the two scenes. Hashes are now completely unique from scene-to-scene, so no locations can have clashing hashes.

Cortex 10.4.9.0

Improvements

• USDScene :
  • Improved performance of setNames( includeDescendantSets = True ) substantially for compositions with instanced prims.
  • Improved performance of readSet( includeDescendantSets = True ) substantially for compositions with instanced prims.
  • Improved performance when reading materials from instanced prims.
  • Added loading of UsdGeomCube prims (as MeshPrimitives).
• SceneInterface : Added _copy argument to Python bindings for readAttribute(), readTransform() and readObject(). Pass _copy = False to receive the original constant result directly instead of a mutable copy. Use with care (typically only for debugging and testing)!
• TypedData : Added move constructors.

Fixes

• USDScene :
  • Fixed loading of __cameras, __lights and usd:pointInstancers sets from within instanced prims.
  • Fixed cancellation when reading UsdGeomSphere prims.

Cortex 10.4.8.0

Improvements

• USDScene : Exceptions thrown by child() are now more descriptive.

Fixes

• USDScene : Fixed hasChild() bug which considered prims to be children when child() and childNames() did not.

Cortex 10.4.7.1

Fixes

• USDScene :
  • The UsdShadeMaterialBindingAPI schema is now applied to all prims with material bindings, making the written files compatible with USD_SHADE_MATERIAL_BINDING_API_CHECK=strict mode.
  • Fixed loading of USDGeomXformable's ResetXformStack operator.
