1.6.3.0

Features

SystemCommand, PythonCommand : Added isolated plug. An isolated task is executed from a script containing only that node. This is a useful optimisation when the load time for the full script is high compared to the time taken to execute the task (#6541).

SceneInspector :
- Added “Isolate Differences” option for comparison modes. This filters out all properties which have the same value in the A and B columns.
- Improved filtering :
  - By default, filters now match any part of the hierarchy, allowing primitive variables to be matched.
  - Filters may optionally specify a full path, such as /Object/Primitive Variables/velocity to avoid matches elsewhere in the hierarchy.
  - The new behaviour matches the filters in the HierarchyView and AttributeEditor.
- Removed redundant scene inspections when not in comparison mode.
Arnold : Added support for M44f header:* output metadata.
FocalBlur : Added presets for focalLengthWorldScale and placeholder text for cameraPath.

Arnold : Fixed options.frame value, which was previously always 0. This fixes the arnold/frame EXR metadata.
SceneInspector :
- Fixed potential crashes caused by a thread-safety bug. These were more likely in layouts with multiple SceneInspectors.
- The Globals tab no longer shows the A/B columns when only locations are being compared.
BoolWidget : Fixed label text styling when disabled.
Scene Editors : Fixed cell background colour when a property is deleted by the current EditScope. It is now blue to indicate the edit, whereas before it had the default colour.
GraphEditor : Fixed duplicate annotations that occurred when default annotation metadata was registered for a particular node type.
Metadata : Removed duplicate items returned by registeredValues().
PlugLayout : Fixed context used to evaluate layout:activator metadata.
Catalogue : Fixed to support IPv4-only environments.
NodeEditor : Fixed error colour for preset widgets.
RenderPass menus : Fixed handling of renderPassPlugValueWidget:displayGrouped and renderPassPlugValueWidget:hideDisabled configuration metadata.
- Fixed error handling. Previously if an error occurred when computing the available render passes, the menu would fail to build.
- Fixed “Refresh” menu item, which is shown when the available render passes are still being computed.
- Changes to the metadata after the menu is created are now reflected in the menu configuration.
- The main menu configuration is saved in the .gfr file.

Metadata : The registerNode() function now accepts dictionaries containing plug metadata. This should be preferred to the previous list-based values.
SceneInspector : Added deregisterInspectors() method.
PathPlugValueWidget : Added support for placeholder text, via pathPlugValueWidget:placeholderText metadata.
TaskNode : Added “dispatcher:allowIsolation” metadata, which can be used to add the isolated plug to a TaskNode.
