5 Nodes L-Q
LightCreate
This node is used to create a Scene Graph containing a light. LightCreate does not load the light from any file or
product but instead builds an entirely novel light from the parameters you specify on this node. This node is not
used generally, the Gaffer node is used instead.
NOTE: LightCreate requires a light shader to function properly.
LightCreate and CameraCreate are identical, except for the type of Scene GraphLocations they create, and the
population of the lightList vs. cameraList.
