LightSet

Overview

A LightSet is a high-level grouping of lights, whose purpose is primarily to specify which lights influence a given geometry object. It is not a physically based construct, but provides artists with a useful and flexible degree of control.

A LightSet is assigned to a Geometry object via its layer entry. For example:

lightSet1 = LightSet("lightSet1") {
    SphereLight("lightA"),
    SphereLight("lightB"),
}

Layer("Scene/layer") {
    {geom1, "", lightSet1}
}

Here, the Geometry object geom1 will be illuminated by the lights in its assigned LightSet, i.e. lightA and lightB. It will not be illuminated by any other lights present in the scene.
