This functions similarly to a LightAttrib or ClipPlaneAttrib.
It indicates the set of occluders that modify the geometry at this level and below. Unlike a ClipPlaneAttrib, an OccluderEffect takes effect immediately when it is encountered during traversal, and thus can only add occluders; it may not remove them.

Some objects require all of their nested pointers to have been completed before the objects themselves can be completed.
If this is the case, override this method to return true, and be careful with circular references (which would make the object unreadable from a bam file).
