Improvements

• CurvesPrimitive :
  • Added Wrap enum, with Periodic, NonPeriodic and Pinned. This generalises the previous periodic boolean property.
  • Added argument names to variableSize() and numSegments() Python bindings, so they can be passed as keywords.
• USDScene : Added support for pinned curves.
• CurvesAlgo : Added isPinned() and convertPinnedToNonPeriodic() utilities.

Fixes

• CurvesAlgo : Fixed handling of periodic curves in deleteCurves().
• CurvesAlgo : Fixed resamplePrimitiveVariable() to handle Vertex<->Varying conversion for linear curves correctly.

Breaking Changes

• CurvesPrimitive : Made protected members private.

API

• Primitive : Added default type to templated function variableData.

Breaking Changes

• HenyeyGreenstein.h : Removed.
• SweepAndPrune.h : Removed.
• RadixSort.h : Removed.

Build

• Added compatibility with USD 25.11 and 26.03.
• CI : Updated to GafferHQ/dependencies 11.0.0a3.

Fixes

• CompoundData : Fixed bad formatting of exception messages ¹.

Breaking Changes

• MessageHandler : Removed support for passing boost::format objects to msg(). Use fmt::format() instead.
• FileSequence : Removed fileNameTemplate() protected method. Use fileNameForFrame() instead.

Improvements

• Canceller :
  • Derived from RefCounted, to allow Cancellers to be shared between multiple clients.
  • Enabled chaining of Cancellers, via addChild() and removeChild() methods and a ScopedChild utility class.
• MessageHandler : Added msg() overload that accepts a fmt::format_string and arguments.
• InternedString : Added specialisation for fmt::formatter<InternedString>.

Breaking Changes

• Canceller : Changed base class.

Build

• Requires fmt 9.1.0.
• Removed unnecessary linking of boost_chrono.

Improvements

• USDScene : Added prim path to warnings when reading curves and meshes.

Fixes

• USDScene : Fixed handling of connections involving UsdShadeNodeGraph interface parameters ¹.

Build

• CI :
  • Updated to GafferHQ/dependencies 11.0.0a2.
  • Build artifacts and releases now include a "-platform##" suffix denoting their target VFX Reference Platform year. This replaces the "gcc" suffix previously used on Linux builds.

Fixes

• USDScene : Fixed handling of connections involving UsdShadeNodeGraph interface parameters.

Improvements

• ShaderNetworkAlgo : Added render adaptor API, allowing just-in-time modifications to
  ShaderNetworks during translation for rendering.
