ArnoldMeshLight
Turns mesh primitives into Arnold mesh lights by assigning a mesh_light shader, turning off all visibility except for camera rays, and adding the meshes to the default lights set.
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 processed output scene.
enabled
The on/off state of the node. When it is off, the node outputs the input scene unchanged.
in
The input scene
filter
The filter used to control which parts of the scene are processed. A Filter node should be connected here.
cameraVisibility
Whether or not the mesh light is visible to camera rays.
parameters
The parameters of the Arnold mesh_light shader that is applied to the meshes.

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.
