Hi Glenn, I can't really give a straight answer without spending some time on the code, but it does sound like CullStack should be returning the viewport of the nested Camera, and if it isn't there is probably a bug lurking somewhere in CullVisitor::apply(Camera&) so I'd recommend having a look at the internals of CullVisitor to see the management of the viewport stack, a little fix is probably all that is required.
