Three procedural maps (bricks, Perlin marble, and splat),
with variations
A procedural map can be generated in two
dimensions, or in three. For example, Wood has a
grain that goes through the assigned geometry. If
you cut away part of an object with wood assigned
as its texture, the grain in the cutaway portion

Shadows created by projecting image o f palm trees
By adding a map to a light, you turn it into a
projector . You can assign a single image, or you
can assign an animation to create the effect of
either a slide projector or a movie projector.
You can also use projector maps to projec t black
and white bitmaps to simulate shadows seen
through leaves or window f rames, in the same way
that gobos are used in theater lighting.
You ’re not limited to circular projectors. Since
you’re usually projecting a rectangular image, you
canusearectangularlighttoprojectit.Youcan
use t he Bitmap Fit option to adjust the aspec t ratio
of the light beam to match that of the projected
image.
When you use projection lights, it’s often helpful
to adjust their roll angle. You can do this with
the navigation controls or with the
