OSLLight

Creates lights by assigning an emissive OSL shader to some simple geometry.

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.

shaderName

The OSL shader to be assigned to the light geometry.

shape

The shape of the light. Typically, disks should be used with spotlight shaders and spheres should be used with point light shaders. The “Geometry” shape allows the use of custom geometry specific to a particular renderer.

radius

The radius of the disk or sphere shape. Has no effect for other shapes.

geometryType

The type of geometry to create when shape is set to “Geometry”. This should contain the name of a geometry type specific to the renderer being used.

geometryBound

The bounding box of the geometry. Only relevant when the shape is set to “Geometry”.

geometryParameters

Arbitary parameters which specify the features of the “Geometry” shape type.

attributes

Arbitrary attributes which are applied to the light. Typical uses include setting renderer specific visibility attributes to hide the shape from the camera.
