Gaffer 1.5.5.0

Features

• Parent, Duplicate, Scatter : Added copySourceAttributes plug, to preserve inherited attributes when the destination is not parented below the source.
• PromotePointInstances : Added a new node for selectively converting a subset of a USD PointInstancer to expanded "hero" geometry.
• Annotations :
  • Added copy and paste of annotations. The right-click menu of an annotation allows you to copy the annotation. Pressing Control + V in the Node Editor will paste the annotation to the selected nodes.
  • Double clicking on an annotation now pops up the annotation editor dialogue.

Improvements

• RenderPassEditor : Added ability to rename a render pass within the edit scope it was originally created in. A render pass can be renamed from the "Name" column via the "Rename Selected Render Pass..." menu item, double clicking on a cell or selecting a cell and pressing Enter or Return.
• VisualiserTool :
  • Changed naming requirements for visualising primitive variables. Values in dataName now prefix the primitive variable name with primitiveVariable:. Setting dataName to vertex:index will display vertex indices.
  • Added mode plug. The available modes are :
    • Auto : Chooses the most appropriate mode based on the data and primitive type.
    • Color (Auto Range) : Float, integer, V2f and color data is displayed without modification. Vector data is remapped from [-1, 1] to [0, 1].
    • Color : Values are remapped from the range [valueMin, valueMax] to [0, 1].
    • Vertex Label : Values are displayed as a label next to each vertex.
  • When visualising data as vertex labels, the value for the vertex nearest the mouse cursor gets visual emphasis. This value is also used for drag and drop.
• PrimitiveVariableTweaks : Added invertSelection plug.
• Tweaks nodes : Added automatic conversion between numeric types. For example, an integer tweak value can now be applied to a float.
• SceneWriter : Improved performance. Benchmarks rewriting complex scenes via a SceneReader->SceneWriter graph show around a 2x speedup.
• USDLayerWriter : Improved performance, including a 50x speedup for one benchmark.
• RenderPassMenu : Added configuration of the default state of "Hide Disabled" and "Display Grouped" via renderPassPlugValueWidget:hideDisabled and renderPassPlugValueWidget:displayGrouped metadata registered in a startup file. For example, "Hide Disabled" can be enabled with the following registration Gaffer.Metadata.registerValue( Gaffer.ScriptNode, "variables.renderPass.value", "renderPassPlugValueWidget:hideDisabled", True ).

Fixes

• ContactSheetCore : Fixed bugs handling changes to the input and output image formats.
• InteractiveRender : Fixed potential leak of scene:path context variable when computing the value for resolvedRenderer.
• Dispatch app : Fixed poor UI layout in "Completed" dialogue state (#6244).
• RenderPassEditor : Fixed errors when script is not parented to an Application.
• MessageWidget : Fixed bug preventing the horizontal scroll bar from appearing when displaying messages with long lines.
• VectorDataWidget, VectorDataPlugValueWidget : Fixed bug preventing dropping a single value onto the + and - buttons and the plug name.

API

• EditScopeAlgo : Added renameRenderPass() and renameRenderPassNonEditableReason() functions.
• SceneAlgo : Added parallelGatherLocations() function.
• GraphGadget : Added annotationsGadget() function.
• MetadataAlgo : Added annotations() variant accepting Gaffer::Metadata::RegistrationTypes. The default is All to match existing behavior and the previous annotations() variant is deprecated.
• AnnotationsGadget : Added annotationAt() function.
• AnnotationUI : Added contextMenuSignal() allowing customisations to the context menu for annotations.
