Operators allow advanced users to override any part of an Arnold scene and modify the Arnold universe at render time. Probably one of the most common use cases is to override parameters (e.g., shaders) inside a procedural (e.g., ASS or Alembic). To achieve this, you must know the Arnold node and parameter names defined inside the procedural.

The following operators are available:

• Collection
• Disable
• Include Graph
• Look Switch
• Materialx
• Merge
• Set Parameter
• Set Transform
• String Replace
• Switch Operator

ArnoldMaterialXBake

Allows exporting of a selection of locations with their corresponding materials, labeled with a MaterialX look. This can be brought back in later with an Arnold Operator (arnoldOperator shader slot, applied to procedurals or to the globals) to apply the look.

ArnoldOperatorBake

Allows for export of any Operators attached to procedurals or to the global options (scene-level operators) to a .ass file.

Export Scene Operators

Includes the Operators attached to the ArnoldRenderGlobals node.

Export Shaders

Includes shaders present in the export. This is useful when Operators are attaching shaders to nodes.

Stand-ins To Export

Specifies which stand-ins' Operators to include in the export. Every stand-in is included by default.
