In
Figure 2-75
, you can see an example of the three types of transparency together.
The knight piece on the left has the Mask option selected, as shown in
Figure 2-76
, and the area defined by
its outline is alpha 0, with the world background visible in the render. Note that things that are in front of the
object are not cut out, such as the middle horse's nose in the image, but the checkerboard wall and floor behind
the piece are cut out to show the sky background. This option is useful for compositing.
Figure 2-75
The knight piece on the left has Mask transparency selected. The piece in the middle has Z trans-
parency selected, and the one on the right has Raytrace transparency.
