A gobo, also
referred to as a cucoloris or cookie, is a cutout shape that is placed in front of a light, sort of
like a cookie cutter. Certain areas of the gobo hold back light, whereas other areas let light
through. In Exercise 4.4, you use a gobo that creates the look of light coming through trees.
Although the previous exercise was basic in design, it is the core lighting situation for many
of your LightWave scenes. Perhaps with a slight variation, this basic three-point lighting
scheme can be used for product shots, animated plays, logos, and much more. Things like
simple stage sets, equipment, figures, generic objects, or any element can benefit from this
type of lighting design. Of course, you are not limited to using just three lights for these
types of situations. You can start with the basic three, and then add or remove lights to
highlight certain areas, brighten dark areas, or use additional lights as projection lights.
Figure 4.22 shows the gobo you??™ll use to create the effect. This image is nothing more than
a photograph of tree branches.Using a simple image-editing program, it was converted to
grayscale mode, its contrast was boosted, and the image was blurred.
