Gaffer 1.4.7.0

Improvements

• ShaderTweaks, ShaderQuery : Improved performance of parameter selection dialogue. For some particularly large shader networks, speedups are greater than 100x.
• UIEditor : Added code examples to button code placeholder text.
• Arnold light_decay :
  • Increased the size of the triangle indicators for the decay ranges.
  • The decay range indicators are now scaled by the light's gl:visualiser:scale attribute.
  • The decay range is now ignored when framing a light in the Viewer.
• EditScopePlugValueWidget :
  • When viewing the output of a Box, the menu now displays the Edit Scopes contained within.
  • Added support for dropping an Edit Scope node onto the widget to set it as the current Edit Scope.
  • Added support for middle-dragging from the widget to access the current Edit Scope node.
• ArnoldAttributes : Added syntax highlighting and auto-complete for set expressions on the shadowGroup plug.
• OpenColorIO : When a script-level OpenColorIO variable contains a Gaffer ${contextVariable} reference, its evaluation is now deferred to the point of use. This allows it to pick up overrides introduced by nodes such as ContextVariables and Wedge.
• SceneInspector :
  • Added support for dragging inspector labels, such as those containing the names of attributes, options, output parameters, parameters, primitive variables, and sets.
  • Set names beginning with "__" such as "__lights" or "__cameras" are now displayed as-is, rather than being transformed to "Lights" or "Cameras".
• BackgroundTask : Added reporting of tasks attempting to wait for themselves.

Fixes

• Viewer : Fixed handling of Gaffer ${contextVariable} references in OpenColorIO variable values. The Viewer now updates the Display Transform appropriately when the value of the context variable changes.
• FramingConstraint : Fixed crash caused by attempts to constrain objects that were not cameras.
• SceneReader : Fixed error loading USD Volumes with empty fields. These will now issue a warning and load as empty locations.
• UI : Fixed hangs caused by garbage collection of removed Editors. One common example involved viewing a Catalogue in the NodeEditor after removing the ImageInspector (#5877).

API

• TextWidget, MultilineTextWidget :
  • Added setPlaceholderText() and getPlaceholderText() methods.
  • Added placeholderText constructor argument.
