Cortex 10.5.9.5

Fixes

• USDScene : Fixed crash loading skinned facevarying normals (bug introduced in 10.5.9.3).

Cortex 10.5.9.4

Fixes

• USDScene : Fixed crash loading a Volume with an empty field.

Cortex 10.5.9.3

Fixes

• USDScene :
  • Fixed crash attempting to write to a file that is already open for reading. An exception is now thrown instead.
  • Fixed loading of skinned facevarying normals.
  • lightLink and shadowLink collections on UsdLuxLightAPI are no longer treated as sets.
• Version.h : Fixed *Version() functions to return the runtime version of the library, not the version that client code was compiled with. Use the CORTEX_*_VERSION macros for compile time checks.
• IECoreUSD : Asset and volume paths now use / in the resolved path on all operating systems. This behavior can be disabled by setting the IECOREUSD_FORCE_ASSET_PATH_FORWARD_SLASH environment variable to a value of 0.

Cortex 10.5.9.2

Fixes

• USDScene :
  • Fixed round-tripping of colons in set names.
  • Fixed hash() to consider animation on ModelAPI extents when hashing the bound.
• ToMayaMeshConverter : Reverted #1386 that no longer locked normals set on the Mesh from the scc to fix issues with Maya incorrectly recomputing normals as Vertex normals when they were originally computed as Face normals.
• CurvesAlgo : Fixed resamplePrimitiveVariables() for use with periodic curves.

Cortex 10.5.9.1

Fixes

• OpenImageIOAlgo : Fixed data() handling of arrays of type TypeDesc::CHAR, TypeDesc::UCHAR, TypeDesc::USHORT, TypeDesc::SHORT, TypeDesc::UINT and TypeDesc::HALF. Among other things, this fixes the round-tripping of ICC profiles in ImageReader/ImageWriter.

Cortex 10.5.9.0

Improvements

• USDScene : hasBound() and readBound() now use UsdGeomModelAPI extents hints if they are available. This behaviour can be disabled by setting the IECOREUSD_USE_MODELAPI_BOUNDS environment variable to a value of 0.

Cortex 10.5.8.0

Improvements

• IECoreUSD::DataAlgo : Added binding for toUSD() function.

Fixes

• ShaderNetworkAlgo : Fixed crash caused by cyclic connections in removeUnusedShaders().
• ShaderStateComponent : Fixed GL rendering failures caused by unsupported values for texture parameters.
• USDScene :
  • Fixed exceptions caused by attempt to write shader parameters with unsupported value types.
  • Fixed duplicate loading of arnold:* primvars on lights as attributes. These are now only loaded as parameters on the light shader.
• IECoreUSD::DataAlgo : Fixed exceptions thrown by toUSD() and valueTypeName() when passed datatypes not supported by dispatch(). An empty VtValue or SdfValueTypeName is now returned instead.

Build

• CI : Updated to GafferHQ/dependencies 8.0.1.

Cortex 10.5.7.1

Fixes

• USDScene :
  • Adding mapping of arnold:* light parameters to and from the non-standard primvars:arnold:* attributes preferred by the arnold-usd project.
  • Fixed writing of treatAsPoint and treatAsLine light parameters, which were being written as generic inputs:* attributes and not the specific attributes defined by the SphereLight and CylinderLight schemas.

Cortex 10.5.7.0

Features

• MeshPrimitive : Added interpolateBoundary, faceVaryingLinearInterpolation and triangleSubdivisionRule properties for controlling the shape of the subdivision limit surface.

Fixes

• MeshPrimitive : Removed interpolation from topologyHash. The topologyHash should only include things which affect the layout of primitive variables.

Cortex 10.5.6.2

Fixes

• USDScene : Fixed round-tripping of ai:light shader type for the output shader of light networks.
