Optimizing With SetDOD
A DOD (Domain of Definition) is a rectangular region around an element that defines
the part of the image you want to include in render calculations. Usually, the DOD is
used to exclude empty image areas from render calculations.
But you can also use SetDOD to crop out parts of an image that you don’t want to
include in your composition. Give it a try.
