1.2.1.0

Features

SetEditor : Added a new editor UI for inspecting sets. This can be found in the tab next to the SceneInspector in the Standard layouts. Sets are displayed hierarchically using “:” characters in set names as separators.
ImageToPoints : Added a new node for converting images to points primitives.
MeshSplit : Added node for splitting a mesh into multiple meshes based on the values of a primitive variable. May be combined with the recently added MeshSegments to split meshes into connected parts.

USD : Added translation of UsdUVTexture’s scale, bias and fallback parameters to Arnold.
StringPlugValueWidget : Added support for converting StringVectorData values pasted or dropped onto the widget. The string value is formed by joining the string array using spaces.
Spreadsheet : Improved support for converting StringVectorData to StringData when dropping values on cells. The string value is formed by joining the string array using spaces.
CompoundPathFilter : Canceller is now passed to member filters.
PathListingWidget : Improved performance when sorting items based on the name column.
Scene : Improved performance computing the bounding box for a primitive.
aiQuadLight : Added width and height parameters.

Locale :
- Reintroduced LC_NUMERIC=C environment variable assignment to wrapper. This was removed in 1.2.0.0 but is still necessary due to a bug in Cortex.
- Fixed serialisation of .gfr files in locales with non-default numeric formatting (#5158).
Tweak nodes : Fixed bugs which prevented the creation of new tweaks when an existing tweak had an input connection.
Preferences : Fixed bug which caused UI metadata to be serialised unnecessarily into ~/gaffer/startup/gui/preferences.py.
OpenGL Texture shader : Fixed bug which allowed transparent regions to obscure objects behind them.
Viewer :
- Fixed visualisation of Arnold image nodes with non-default UV Coordinates settings.
- Fixed Arnold selection bugs caused by the ai:fis_filter option.
SceneReader : Invalid primitive variables in USD files are now skipped during loading, with a warning being emitted instead.
DeleteFaces : Fixed sudivision crease handling bug.
USD RectLight : Fixed the orientation of textures applied to the light to be oriented with the top-left of the image at the top-left of the quad light when viewed from an object receiving illumination.

Added more Python examples to the Scripting Reference “Common Operations” article.
Added instructions for installing and configuring Gaffer on Windows to the “Getting Started” guide.

RGBAChannelsPlugValueWidget : Added support for rgbaChannelsPlugValueWidget:allowNone metadata.
