Release Gaffer 1.3.3.0 · GafferHQ/gaffer

Features

3Delight :
- Added support for VDB volume objects.
- Added support for vdbVolume shader.
- Added support for volumeshader and displacementshader attributes.
- Added support for spline parameters in shaders.

SceneReader : Added support for reading from in-memory USD stages using a filename of the form stageCache:{id}.usd where {id} specifies a stage which has been inserted in the UsdUtilsStageCache.
Resample, Resize, Blur, ImageTransform : Improved performance, resulting in a 3x speedup in an obscure case, and a 5-10% speedup in more common cases.
ImageSampler : Added interpolate plug to control interpolation. Previously created ImageSamplers are unaffected, but interpolation is off by default for newly created ImageSamplers.
3Delight :
- Moved shaders to 3Delight/Shader menu and removed outdated shaders from the menu.
- Shaders (including light shaders) are only loaded from the osl subdirectory of the 3Delight installation.
- Primitive variables named uv are now automatically renamed st for compatibility with the uvCoord shader's expectation.
- Added a default uvCoord shader during internal shader network preprocessing to shader parameters that do not have an input connection.
SetEditor : Added columns for controlling the Visible Set membership of set members. These allow the current members of a set to be included or excluded from the Visible Set by clicking within the Set Editor's Inclusions and Exclusions columns.

SceneReader :
- Fixed handling of invalid values on the following USD attributes :
  - PointBased : positions, normals, velocities, accelerations.
  - Curves : widths.
  - PointInstancer : ids, protoIndices, orientations, scales, velocities, accelerations, angularVelocities.
  - Points : ids, widths.
    Invalid values are now ignored with a warning, instead of loading as invalid primitive variables.
- Fixed treatment of unconnected material outputs. If they were "authored" but not connected to a source, they were incorrectly being treated as valid attributes, and were being loaded as empty ShaderNetworks which caused problems elsewhere.
DispatchDialogue : Changed the button label for the results display from "Ok" to "Close".
Viewer : Fixed display of infinite values in the pixel inspectors. These were being incorrectly displayed as nan instead of inf.
OptionTweaks : Fixed bug that prevented multiple tweaks being made to the same option in one node.

SceneAlgo :
- Added findAll() method, for finding all scene locations matching a predicate.
- Added findAllWithAttribute() method, for finding all scene locations with a particular attribute.
ThreadState : Added process() method.
Process : Added const overload for handleException() method. The non-const version will be removed in future.
ContextMonitor : Added Statistics::variableHashes() method, allowing introspection of specific variable values.
