Gaffer 1.2.0.0a2

[johnhaddon]

Features

• ContextVariableTweaks : Added a new node for tweaking the context used to evaluate upstream nodes ¹.

Improvements

• Light Editor :
  • Added a "Mute" column for toggling a light's mute attribute on and off.
  • Added a "Disable Edit" command to the right-click menu, to easily disable tweaks in EditScopes (shortcut D).
  • Added a "Remove Attribute" command to the right-click menu, to delete attributes using the EditScope (shortcut Delete).
• Cycles ¹ :
  • Replaced size on portals and quad lights with separate width and height parameters, and renamed size parameter of disk lights to width.
  • Added use_camera, use_caustics and normalize parameters to lights.
• TweakPlug : Added a CreateIfMissing mode, to only create a new value if one does not currently exist ¹.
• OSLObject : Added support for attribute substitutions using <attr:myAttrName> syntax in string parameters, provided that useAttributes is turned on ¹.
• UIEditor : Increased maximum size of the "Button Click Code" editor ¹.
• HierarchyView : Inclusions and Exclusions column header icons now update to show when one or more locations have been added to or excluded from the Visible Set ².
• Light : Added an enable/disable toggle to the mute plug ².
• AttributeTweaks : Added Remove mode.
• NodeEditor : Added "Promote Value and Switch" context menu item for promoting NameValuePlugs to Boxes ¹.

Fixes

• Viewer ¹ :
  • Fixed Default display transform so that it updates correctly when the default is changed via the Preferences dialogue, and when the context changes.
  • Fixed drawing of image pixels to the left of the display window.
• 3Delight : Fixed rendering with recent versions of 3Delight, which no longer use the DL_DISPLAYS_PATH to search for display drivers.
• Metadata :
  • Fixed memory leak.
  • Fixed thread safety bug that prevented concurrent access to metadata for the same plug or node from multiple threads.
• Cycles ¹ :
• Fixed custom AOVs (for SVM shading mode only, Cycles doesn't support custom AOVs in OSL mode) (GafferCycles : Custom AOV fix + unit test #5044).
• Fixed units for distant light angle (now degrees and not radians).
• Fixed assignment of emission shader. Previously this was being assigned as a cycles:light attribute instead of cycles:surface (Cycles emission rendering as default material. #5058).
• Hid internal shader plugs which shouldn't be exposed to the user (e.g. surface_mix_weight).
• ImageViewer : Fixed drawing of pixels to the left of the display window ¹.
• UVInspector : Fixed update delay when changing display transform ¹.
• Random : Fixed GIL management bug which could lead to hangs ¹.
• ShufflePrimitiveVariables, ShuffleAttributes, OptionQuery, PrimitiveVariableQuery, ShaderQuery, ContextQuery, CreateViews, SetVisualiser, OSLImage, OSLObject, OSLCode, Outputs : Fixed bugs which allowed read-only nodes to be edited.
• ShaderTweaks : Fixed Remove mode ¹.
• FilterQuery : Fixed bug which prevented the output from updating when the input scene changed (FilterQuery does not update on incoming set changes #5066) ¹.
• Arnold : Fixed rendering of token enum parameter values loaded from USD ¹.

API

• PlugValueWidget : Added new API to provide asynchronous updates. The old _updateFromPlugs() and _plugConnections() methods are deprecated, and support for them will be removed in a future version.
• PlugAlgo : Added dependsOnCompute() utility method.
• FileSystemPath :
  • Added a constructor that accepts a filesystem::path.
  • Added a standardPath() method returning a std::filesystem::path object in C++ and a pathlib.Path object in Python.

Build

• 3Delight : Updated to 3Delight version 2.9.17.
