I suspected that's how it's usually done, but you never know. There are always little things that make huge differences. For instance, "cheating" on set in film means to move something to a new place after shooting it from one angle to accomodate a new angle, and doesn't sound like much of an option when rendering from within one scene, so for cheating, if necessary, it may be useful to duplicate the scene and build a "cheated" version? But then if you decide you don't like some bit of animation in the non-cheated, you would have to update the cheated one as well. Any hints on that note?
