The Exclude/Include dialog determines which
objects are not i lluminated by a selected light, or
which objects are considered in a Matte render
element (page 3–130).
Although light exclusion does not occur in nature,
this feature is useful when you need exact control
over the l ighting in your scene. S ometimes, for
example, you’ll want to add lights specifically to
illuminateasingleobjectbutnotitssurroundings,
or you’l l want a light to cast shadows from one
object but not from another.
