• Arnold : Added multi-layer EXR support. All outputs with the same filename are now written to the same file via a single output driver.
• ImageSelectionTool :
  • Added new tool that allows selecting scene paths based on an image. Works with both Catalogue images and images on disk. Has two requirements : an id AOV (added using the ID preset on an Outputs node), and a render manifest (added using StandardOptions > Render Manifest > File Path ).
  • Also supports picking instance IDs, using an instanceID aov. Supported when rendering an instancer that is encapsulated ( USD instancers rendered to Arnold are encapsulated by default ).
• ColorInspectorTool : Moved the Viewer's colour inspectors into a dedicated tool, selected from the toolbar on the left.
• OSLObject : Added the ability to use pointcloud_search() and pointcloud_get() to query geometry from arbitrary scene locations.
• CameraQuery : Added a new node to query camera parameters (#6431).
• Cycles : Updated to version 4.4.0.
• SceneInspector :
  • Rewrote using the same framework as LightEditor, AttributeEditor and RenderPassEditor.

Improvements

• Viewer : Added Add image comparison mode.
• RenderMan :
  • Added dedicated viewport visualisers for RenderMan lights.
  • Removed the GAFFERRENDERMAN_FEATURE_PREVIEW environment variable. The RenderMan extension is now automatically enabled any time the RMANTREE environment variable is present. While the RenderMan extension is not yet feature complete, it is considered to be mature enough for general use.
• Arnold : Improved readability of shader node names as they appear in statistics and .ass files. They are now formatted as shader:{handle}:{uniqueId} where {handle} is the Gaffer node name of the assigned shader, or if loaded from USD, the prim name.
• DeleteAttributes : Optimised case where all attributes are deleted. The input attributes are no longer accessed at all in this case.
• ShaderAssignment : The scene:path context variable is now available in Switches connected directly to the ShaderAssignment.shader input. This allows different shaders to be assigned to different locations using a single ShaderAssignment node. Please note that the scene:path context variable remains unavailable to the individual shader nodes themselves for performance reasons.
• 3Delight, Cycles, OpenGL : Added support for custom EXR metadata, using header:* parameters on the output definition.
• RenderManAttributes, RenderManOptions : Plugs now respect minimum and maximum values specified by RenderMan.
• RenderManShader : Improved GraphEditor labels for parameter RGB and XYZ components.

• PrimitiveInspector : Added location widget for selecting the location to be inspected.
• OptionalValuePlugValueWidget : The widget for the enabled plug can now be customised using plugValueWidget:type metadata.
• GafferML : Added experimental support for performing inference on CUDA devices. This can be enabled by setting the GAFFERML_USE_CUDA environment variable with a value of 1. This requires an ONNX runtime containing the CUDA execution provider, with compatible versions of the CUDA toolkit and cuDNN installed.
• ShaderTweaks :
  • Added support for inserting new connections in Create mode.
  • Added initial support for inserting connections to closure parameters (#6522).
  • Added dragging of plugs onto the + button in the NodeEditor, to create a tweak for values of that type. Particularly useful for making tweaks for closure parameters.

API

• ScenePlug : Added optional withGlobalAttributes arguments to fullAttributes() and fullAttributesHash().
• VectorDataWidget : Added optional maximumVisibleRows argument.

Breaking Changes

• StandardLightVisualiser : Removed protected methods for drawing visualiser elements. These are now part of GafferSceneUI::Private::LightVisualiserAlgo. This namespace can be used by light visualisers, but is currently Private while the API details are being resolved.
• AttributeTweaks : Tweaks with localise enabled and a mode of CreateIfMissing will now not create an attribute if it is missing from the scene hierarchy, but exists in the globals.

Breaking Changes

• Arnold :
  • Removed support for Arnold 7.2.
  • Removed GafferArnoldUI.GPUCache.populateGPUCache() function.
• ArnoldAttributes, CyclesAttributes, DelightAttributes, OpenGLAttributes, StandardAttributes, USDAttributes : Attributes plugs have been renamed to match the name of their attribute (e.g. attributes.visibility is now attributes.scene:visible). Compatibility configs have been provided to allow these nodes to be loaded from scripts saved in earlier Gaffer versions.
• ArnoldOptions, CyclesOptions, DelightOptions, StandardOptions : Option plugs have been renamed to match the name of their option (e.g. options.renderCamera is now options.render:camera). Compatibility configs have been provided to allow these nodes to be loaded from scripts saved in earlier Gaffer versions.

• OpenGLAttributes : The default values of the attribute plugs authoring the gl:primitive:bound, gl:primitive:outline, gl:primitive:points, gl:primitive:pointColor, gl:primitive:wireframe, and gl:primitive:wireframeColor attributes have changed to match the default behaviour of the OpenGL renderer. Scripts loaded from previous Gaffer versions with these plugs enabled and set to the default value will see a difference in OpenGL renders.
• SceneTestCase : Removed assertBoxesEqual() and assertBoxesAlmostEqual() methods.
• RenderController : Removed pathForID(), pathsForIDs(), idForPath() and idsForPaths(). Use renderManifest() instead.
• Catalogue, CatalogueSelect, Display : Moved from GafferImage module to GafferScene.
• StandardAttributes : Changed the default value of the linkedLights plug to "defaultLights". Scripts loaded from earlier Gaffer versions containing linkedLights plugs set to the previous default of "" will need to be updated as those plugs will now default to "defaultLights".

Build

• SConstruct : Added GAFFER_COMMAND option to control the command to be called during install.
• Cortex : Updated to version 10.5.15.1.

API

• GraphComponent : Added support for compatibility:childAlias:{aliasName} metadata, which specifies the name of a child to be accessed via the alias {aliasName}. The Python methods getChild(), descendant(), __getitem__, __delitem__, and __contains__ now fall back to using aliases when a direct match is not found. This metadata can be registered to maintain compatibility when renaming plugs.

Features

• ShuffleOptions : Added a new node for shuffling options in the scene globals (#6412).

Improvements

• Animation :
  • Added plug context menu actions for color, vector and box plugs.
  • Plug context menu actions are now available on widgets that edit multiple plugs. This enables the animation of multiple cells at once in the LightEditor, RenderPassEditor, AttributeEditor and Spreadsheet UI.

• RenderManShader : Fixed failure to load connections made via Dots and other intermediate nodes.
• Expression : Fixed error when creating OSL expressions for plugs with : characters in their name.
• PythonEditor : Fixed completions menu not appearing after typing : in a partial plug or node name or a dictionary key.

Build

• Added buildGraphics option to SConstruct to enable building the Gaffer logo and icons separately.
• Cortex : Updated to version 10.5.15.0.

Improvements

• StandardAttributes : Added shadowedLights attribute to specify shadow linking. This supercedes the Arnold-specific shadowGroup attribute on the ArnoldAttributes node.

Features

• ArnoldProcedural : Added a new node for making Arnold .ass procedural placeholders.
• AttributeEditor, LightEditor, RenderPassEditor : Added copy and paste editing. Values from one or more cells can be copied to the clipboard with Ctrl + C and pasted with Ctrl + V to create or update edits. Values copied from these editors can also be pasted into Spreadsheet cells, and vice versa.

Improvements

• ImageReader : Automatically set "filePath" metadata when reading images, making it easier to determine the path an image was loaded from.
• Cryptomatte : Improved automatic finding of manifests. Now, if the image's metadata references a sidecar manifest file, but no explicit manifestDirectory is specified, it will look in the directory the image was loaded from (as determined by the "filePath" metadata). This makes it more likely that cryptomatte files will work automatically.
• Spreadsheet :
  • A wider range of types are converted when copy/pasting values between cells, such as BoolData to IntData, FloatData to IntData, etc.
  • Added support for converting StringData values when pasted or dropped onto a StringVectorData cell. The string array value is formed by splitting the string on spaces.
• AttributeEditor, LightEditor, RenderPassEditor, Spreadsheet : The current text is selected automatically when editing popup multi-line text fields.

Fixes

• Cycles : Fixed light linking in batch renders.
• RenderMan :
  • Fixed light linking in batch renders.
  • Fixed handling of render:{name} attributes, such as the render:displayColor attribute created by StandardAttributes, and primvar:{name} attributes loaded from USD files. These can now be accessed by PxrAttribute shaders as either user:{name} or just {name}.
• Cryptomatte : Fixed hypothetical inconsistencies if the C++ language locale affects the parsing of JSON files (probably not an issue in practice, since the JSON in question should just be hexadecimal integers, and no known locale should affect the parsing of integers).
• Alembic : Fixed crashes caused by invalid UVs.

Build

• Cortex : Updated to version 10.5.14.0.

API

• PlugAlgo :
  • Added support in setValueFromData() for setting StringPlug values from StringVectorData and StringVectorDataPlugValues from StringData.
  • Added setValueOrInsertKeyFromData().
