Gaffer 1.4.4.0

[murraystevenson]

Features

• RenderPassEditor :
  • Added type column for configuring specific passes to render with a predefined type. We provide default configurations of a number of render pass types, these can be modified to suit specific workflows via the RenderPassShader node or by registering new types and processors via the RenderPassTypeAdaptor in a startup file.
  • The default render pass type configurations include :
    • A "shadow" type for catching shadows cast by caster locations on catcher locations.
    • A "reflection" type for catching reflections cast by caster locations on catcher locations. The roughness of the reflective material can be configured per catcher location by creating a user:renderPass:reflectionCatcher:roughness float attribute.
    • A "reflectionAlpha" type for catching reflection mattes cast by caster locations on catcher locations. The colour of the matte can be configured per caster location by creating a user:renderPass:reflectionCaster:color Color3f attribute.
• RenderPassShader : Added new node for overriding a shader used by a render pass type.

Improvements

• 3Delight :
  • Added support for multipart EXR renders by using the same file name parameter on multiple outputs.
  • Added support for scalarformat, colorprofile, filterwidth and arbitrary custom NSI outputlayer and outputdriver attributes.
  • Updated the default output presets to include scalarformat, colorprofile, filter and filterwidth output parameters.
• LightPositionTool : Changed the pointer to notEditable when using keyboard combinations that do not apply to the current tool mode.
• LightEditor : Added the ability to register columns for editing any parameter in a light's shader network. The parameter to edit is registered in the form shaderName.parameterName when calling GafferSceneUI.LightEditor.registerParameter.
• PathFilterUI : Added the ability to drag and drop scene paths onto Box and Reference nodes. Doing so will create a new PathFilter with the selected paths if none is connected, or update an existing connected PathFilter.

Fixes

• SceneReader, SceneWriter : Fixed handling of Arnold-specific parameters on UsdLux lights.
• SceneWriter : Fixed import of treatAsPoint and treatAsLine parameters on UsdLux lights.
• Linux : Fixed crashes at startup on platforms - including RHEL 9.4 - with a more recent glibc (Segmentation fault at Startup Linux #5856).
• LightPositionTool : Fixed bug that allowed a non-light object to be moved by clicking or dragging the target or pivot.
• OptionQuery : Fixed bug which allowed the scene:path context variable to leak into the context used to evaluate the globals.

API

• ShaderPlug : Added parameterSource() method returning the ValuePlug responsible for generating a parameter in a shader network.
• ParameterInspector : Added the ability to inspect parameters on any shader in a light or shader's shader network.
• RenderPassTypeAdaptor :
  • Added registration methods for defining render pass types and processors.
  • Added registerAutoTypeFunction() method to define a function used to automatically derive the render pass type from the render pass name when the renderPass:type option value is "auto".
