ust make sure to do everyhting Autodesk requires so they don't penalize you but they don't judge you on them so go to town if you like and do just about anything (clean) that you wish as long as you wish (if you want to make a five hour long credit sequence, knock yourself out!
).
Just make sure that everything from paperwork to disks to the animation itself is taken care of first.
