ArnoldLight

Loads an Arnold light shader and uses it to output a scene with a single light.

user

Container for user-defined plugs. Nodes should never make their own plugs here, so users are free to do as they wish.

out

The output scene.

enabled

The on/off state of the node. When it is off, the node outputs an empty scene.

name

The name of the object in the output scene.

sets

A list of sets to include the object in. The names should be separated by spaces.

transform

The transform applied to the object.

parameters

The parameters of the light shader - these will vary based on the light type.

defaultLight

Whether this light illuminates all geometry by default. When toggled, the light will be added to the “defaultLights” set, which can be referenced in set expressions and manipulated by downstream nodes.

visualiserAttributes

Attributes that affect the visualisation of this Light in the Viewer.

visualiserAttributes.scale

Scales non-geometric visualisations in the viewport to make them easier to work with.

visualiserAttributes.maxTextureResolution

Visualisers that load textures will respect this setting to limit their resolution.

visualiserAttributes.frustum

Controls whether applicable lights draw a representation of their light projection in the viewer.

visualiserAttributes.lightFrustumScale

Allows light projections to be scaled to better suit the scene.

visualiserAttributes.lightDrawingMode

Controls how lights are presented in the Viewer.
