Creating an Incandescence Light

An incandescence light source can be created in the GafferThree's Object table by right-clicking in the light list section and selecting Add → Incandescence Light, or by pressing the I key. Incandescence lights are not drawn in the Viewer; the object they control normally is.

Info

The GafferThree node should be placed downstream of the nodes that define the geometry to control, its material and its material assignment in order for the Incandescence Light to operate properly.

Shaping the Incandescence Light

The Geometry to Control parameter from the Object tab specifies the scene graph location of the object or group of objects whose incandescence attributes will be controlled.

These parameters act as multipliers of the controlled geometry's incandescence color. The original material's Incandescence Intensity parameter will be multiplied by this value.
