Gaffer 1.2.3.0

[murraystevenson]

Features

• Arnold : Added support for Arnold 7.2.
• PointsToLevelSet : Added a new node for converting points primitives into OpenVDB level sets.

Improvements

• ArnoldOptions : Exposed Arnold 7.2.1.0's Global Light Sampling feature via a new lightSamples plug.
• ArnoldAttributes : Added shadowAutoBumpVisibility plug, since Arnold 7.2.1.0 now correctly implements this feature.
• Shader : Added support for shading input connections to splines. After double clicking on a spline to open the editor, you may select a control point, and then drag an input to the value control. Works in GafferImage, GafferObject and Arnold. Supports a max of 32 values in the spline.
• FloatSpline and ColorSpline OSL shaders : Added a direction parameter, with options of U, V, Diagonal, Radial and Custom.
• Constraint : Disabled the referenceFrame plug in the NodeEditor when keepReferencePosition is off.

Fixes

• OSLObject/OSLImage : Fixed missing + buttons in GraphEditor on Windows (OSL Object node on windows has no "+" plug input by default #5222).
• Viewer : Fixed missing VDB visualisations on Windows (VDB does not draw on windows version #5223).
• SceneReader : Fixed reading of USD primitives containing primvars:normals. These are now correctly loaded as a primitive variable called N, taking precedence over the UsdGeomPointBased normals attribute.
• SceneWriter : Fixed writing of indexed normals to USD files, so that the indexing is retained on load. Note that this means that normals are now always written as primvars:normals and never via the UsdGeomPointBased normals attribute.
• CompoundDataPlugValueWidget : Fixed bug which prevented the addition of new plugs when an existing plug had an input connection. This affected the ContextVariables, CustomOptions and CustomAttributes nodes, among others.

API

• NoduleLayout : Added a warning message when a required custom gadget has not been registered.
• GafferUITest.TestCase : Added testing of NodeGadgets to assertNodeUIsHaveExpectedLifetime().
• SceneView : Added Python binding for resolutionGate() method.
• ViewportGadget : Added Python binding for RasterScope class.
• OSLShader : Added support for visibleExpression and enabledExpression metadata in OSL shaders. These may provide an OSL expression to control the activation of parameters in Gaffer's node editor.

Build

• Cortex : Updated to version 10.4.7.0.
