Each scene includes a sophisticated set of lights that function like those in a real display setting. The Lights manager node, which has its own pop-up menu, contains all of the light nodes in the scene.
These lights can help you study an object's design, or generate images for presentation documents. Unlike the lighting of displayer surfaces, which determines how parts within a particular displayer will absorb the light, this lighting affects the scene as a whole.
In particular, the manager object allows you to restore default settings and use the head light feature.
