Common Lighting Rollouts and Dialogs
Exclude/Include Dialog
Create a light. > General Parameters rollout > Exclude button
Rendering menu > Render > Render Setup dialog > Render Elements panel >
Render Elements rollout > Add button > Render Elements dialog > Select an
existing Matte element in the list. > Matte Texture Element rollout > Include
button
The Exclude/Include dialog determines which objects are not illuminated by
a selected light, or which objects are considered in a
Matte render element on
page 6336.
Although light exclusion does not occur in nature, this feature is useful when
you need exact control over the lighting in your scene. Sometimes, for example,
you'll want to add lights specifically to illuminate a single object but not its
surroundings, or you'll want a light to cast shadows from one object but not
from another.
