Gaffer 1.2.0.0a3

[johnhaddon]

Features

• MeshSegments : Added a node for identifying faces in contiguous segments. ¹

Improvements

• Viewer : If Arnold is available, then it is preferred over Appleseed for performing OSL shader previews. If neither is available, then Cycles will be used (OSL shaders doesn't preview in the Viewer on Windows version #5084).
• FormatPlugValueWidget, ChannelPlugValueWidget, ChannelMaskPlugValueWidget, RGBAChannelsPlugValueWidget, ViewPlugValueWidget : Added support for showing multiple plugs at once, as needed when multiple Spreadsheet cells are selected for editing.
• Spreadsheet : Improved display of image formats.
• USD : ¹
  • Added support for Arnold-USD's convention for representing connections to individual indices of an array.
  • Added loading of float4 USD shader parameters as Color4 parameters in Gaffer.

Fixes

• Viewer : Fixed bug which made it impossible to switch back to a previously used display transform ¹.
• Cycles : Disabled auto-tiling mode for the viewport/interactive render mode, which caused odd/glitchy behaviour on larger than 2k renders ¹.
• Arnold : The ai:GI_diffuse_depth and ai:GI_specular_depth options now default to 2 when they are left unspecified, matching the default values on the ArnoldOptions node.
• Menu buttons : Fixed missing dropdown menu indicators.
• CompoundNumericPlugValueWidget : Fixed failure to construct with an empty list of plugs.
• ChannelPlugValueWidget : Fixed compatibility with multi-view images.
• FilteredSceneProcessor :
  • Fixed bugs which allowed read-only nodes to be edited.
  • Fixed undo for Remove menu item in Filter tab.
• 3Delight : Fixed bug preventing 3delight from loading on Windows. (3Delight interactive render crash #5081). This also caused errors in the light editor at startup : IECore.Exception: File "maya/osl/pointLight" could not be found. ²
• NodeEditor : Fixed bugs in handling of "green dot" non-default-value indicators with nested plugs.
• GUI App : Fixed error on Windows when launching the gui app after a previous launch loaded a script with \ in the path. ²
• HierarchyView : Fixed P and N editor focus hotkeys ¹.

API

• PlugAlgo : Added findDestination() utility method.

Breaking Changes

• Arnold : Changed the default values for the ai:GI_diffuse_depth and ai:GI_specular_depth options.

Build

• Cortex : Updated to 10.4.4.0. ¹
