The Lighting Render Element stores direct lighting and diffuse color information.
Overview
The Lighting Render Element stores direct lighting information from lights in the scene and materials as lit by the scene's lighting. This render element can be used to brighten, lessen, or tint just the direct lighting in a composite without affecting indirect light or reflections, for example.
The Lighting pass is the same as Raw Lighting multiplied by Diffuse. Lighting is provided as a convenience to the compositor.
