Features

• IECore : Added Rampff, RampfColor3f, RampfColor4f and corresponding Ramp*Data classes, for representing user facing shader ramp parameters.

Breaking Changes

• IECoreScene::ShaderNetworkAlgo :
  • Removed deprecated functions componentConnectionAdapterLabel, convertOSLComponentConnections, collapseSplineParameters, expandSplineParameters.
  • Switch support for Spline parameters to support for Ramp parameters.

Fixes

• USDScene : Fixed reading of animated parameters on materials and lights.
• Boost : Fixed compatibility with Boost 1.85.

Build

• SConstruct : Added INCLUDE_PATHS option.

Improvements

• ShaderNetwork : Optimised applySubstitutions() for cases where not all shaders need them.
• CurvesPrimitiveEvaluator : Added accessors for getting interpolation coefficients and data indices from Result.

Fixes

• ShaderNetwork::hashSubstitutions : Fixed shader string substitutions that are escaped with backslashes (ie. myText\<substitutionHandledByArnold\>).

Improvements

• ShaderNetworkAlgo : Added support for RenderMan's spline convention in expandSplines() and collapseSplines().

Fixes

• ConfigLoader : Fixed UnicodeDecodeErrors in non-UTF8 locales.
• USDScene : Fixed identifiers for exported RenderMan shaders, by omitting the ri: type prefix.

Fixes

• DisplayDriverServer : Fixed to support IPv4-only environments.

API

• TypeIds : Claimed range for AtomsGaffer.

Improvements

• IECoreUSD: Added support for root level tags (reading/writing) to our IECoreUSD::SceneCacheData plugin.

Fixes

• IECoreUSD: Fixed crash when using invalid file path with IECoreUSD::SceneCacheFileFormat.

Fixes

• USDScene : Worked around numerical imprecision when converting between time and UsdTimeCode.

Build

• CI : Updated to GafferHQ/dependencies 10.0.0.

Fixes

• USDScene : Worked around numerical imprecision when converting between time and UsdTimeCode.

Improvements

• RefCounted, RunTimeTyped : Inlined constructor and destructor.

Fixes

• USDScene :
  • Fixed writing of shutter values from cameras without a shutter parameter. The shutter:open and shutter:close attributes are now omitted instead of being written with Cortex's default -0.5, 0.5 shutter values.
  • Fixed reading of shutter values from cameras without shutter:open and shutter:close attributes. The shutter parameter is now omitted instead of being created with USD's default 0, 0 shutter values.
• CurvesPrimitiveEvaluator : Fixed error in Result::vTangent() function causing tangent to point in opposite direction for curves with Linear interpolation.

Breaking Changes

• Renderable : Removed render() method.
• CoordinateSystem : Removed transform.
• Font : Removed meshGroup() method.
• Options, Group, Transform, MatrixTransform, MatrixMotionTransform, AttributeState, Light, MotionPrimitive : Removed.
• CurveExtrudeOp, IDXReader : Removed.
• PreWorldRenderable, StateRenderable : Removed. All derived classes now derive directly from Renderable.
• Renderer, AttributeBlock, EditBlock, MotionBlock, TransformBlock, WorldBlock : Removed.
• IECoreHoudini : Removed.
• IECoreMaya : Removed.
• IECoreNuke : Removed.
• Removed support for IECORE_RTLD_GLOBAL environment variable.
• SmoothSkinningData : Removed, along with all associated Ops and Parameters.

Fixes

• VDBObject : Fixed worldBound() result when bbox metadata not already present.

API

• SConstruct : Install "private" headers.
• VDBObject : Marked metadata() as deprecated.
