Gaffer 0.62.0.0 alpha 2

[johnhaddon]

Features

• ImageReader : Improved support for multi-part OpenEXR files, including fixes for reading many non-standard-conforming files from 3rd party software (ImageReader : Default channels from "rgba_main", "rgba.main", and "depth_main" subimages #4559). The new channelInterpretation plug controls the naming of channels loaded from multi-part files.
• ImageWriter : Added support for writing multi-part OpenEXR files using a new layout plug. This includes presets for standard conforming single-part and multi-part files, and several presets that match Nuke's behaviour.
• Viewer : Added FPS counter option to Gadget menu.

Improvements

• USD : Added basic support for loading UsdLux lights. The data is available in Gaffer, but needs manual conversion to meet the requirements of a specific renderer.
• ImageReader/ImageWriter : Added support for JPEG 2000 (.jp2) images.
• Spreadsheet : Added activeRowIndex plug, which outputs the index of the currently active row.
• InteractiveArnoldRender : Added support for an updateInteractively bool parameter for render outputs. This can be used to request more frequent updates for AOVs other than the beauty image.
• ChannelPlugValueWidget : Improved the ordering of channel names presented in the menu.
• PresetsPlugValueWidget : The children of compound plugs are now shown when in "Custom" mode.

Fixes

• AnimationEditor : Fixed glitches in the drawing of tangent handles during drags.
• ArnoldMeshLight : Fixed bug which caused ai:autobump_visibility attributes to be inadvertently modified.
• ArnoldShader/ArnoldLight : Fixed potential buffer overrun when loading color parameters with gaffer.plugType metadata.
• Plug :
  • The removeOutputs() method now also removes any outputs from child plugs. This is consistent with the setInput() method, which has always managed child plug inputs.
  • Fixed bug which meant that child output connections were not removed when a plug was removed from a node.
• Expression : Fixed error when updating an expression which was previously connected to a deleted spreadsheet row (Spreadsheet row deletion and expression node #4614).
• ViewportGadget :
  • Fixed setCenterOfInterest() so that it doesn't emit cameraChangedSignal() if the center of interest is unchanged.
  • Added GIL release in setViewport() Python bindings.
• ArnoldRender : Fixed rendering of single-channel AOVs specified using Gaffer's generic float|int|uint <name> syntax. Outputs specified using Arnold's <name> FLOAT|INT|UINT syntax will now issue a warning, and should be updated to use the generic syntax.
• Constraint : Restricted targetVertex to positive integers.

API

• ImageAlgo : Added sortChannelNames() function.
• NodeAlgo : Added support for presets on compound plugs. If all child plugs have a particular preset then the parent plug is considered to have it too, and calling applyPreset( parent, preset ) will apply it to all the children.

Breaking Changes

• ImageReader : Changed the default interpretation of channel names in multi-part OpenEXR files. Set the channelInterpretation plug to Legacy to preserve the old behaviour.
• ImageWriter : Multi-part OpenEXR files are now written by default. Set the layout plug to Single Part to write a single-part file instead.
• SubTree : Removed the / root location from generated sets, because root membership is unsupported elsewhere in Gaffer.
• OSLShader : Removed prepareSplineCVsForOSL() method. Use IECoreScene::ShaderNetworkAlgo::expandSplineParameters() instead.
• ArnoldMeshLight : The ai:autobump_visibility attributes are no longer modified. Use a separate ArnoldAttributes node if necessary.
• Spreadsheet :
  • Renamed activeRowNames plug to enabledRowNames. Backwards compatibility is provided when loading old .gfr files.
  • Renamed ui:spreadsheet:activeRowNamesConnection metadata to ui:spreadsheet:enabledRowNamesConnection.

Build

• Qt : Updated to version 5.15.3.
• LLVM : Updated to version 11.1.0.
• OpenJPEG : Added version 2.4.0.
• Subprocess32 : Now packaged as a regular module rather than as a .egg package.
