A layer's Multi-Light attributes.

Multi-Light
The Multi-Light section lets you render separate lighting element contributions at once. Selecting one or more lighting elements in the UI will produce as many additional outputs for each shading component image layer in the Image Layer list. Each output will only contain the light emitted from the selected lighting element.

This powerful feature lets you then composite lighting elements in comp or mix them using 3Delight Display.

An example of how this feature can be used is detailed in Multi-Light Rendering.

Selecting Rigs and Lights Image Layers

The light sources and rigs defined by upstream GafferThree nodes are listed in the Multi-Light section. All light sources that are in a rig will be rendered in a single multi-light image layer. Enabling the Display All Lights option will add every light contained in rigs under the Lights section of the multi-light list. It then becomes possible to generate independent multi-light image layers for some or all of the lights that are in a rig.

Handling Missing Lighting Elements

The Multi-LIght list refers to scene graph locations. If a light source is renamed, disabled or muted in the GafferThree, or if the GafferThree is disconnected, a warning will appear in the Multi-Light section of DlSettings. The missing light image layers will still be rendered (as black image layers), unless the missing light is deselected in the Multi-Light list.
