CyclesMeshLight

Turns mesh primitives into Cycles mesh lights by assigning an emission 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.

lightGroup

The light group that the mesh light will contribute to.

parameters

The parameters of the Cycles emission shader that is applied to the meshes.

parameters.color

Refer to Cycles’s documentation of the emission shader.

parameters.strength

Refer to Cycles’s documentation of the emission shader.

parameters.surface_mix_weight

Refer to Cycles’s documentation of the emission shader.

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.
