I'm trying to make an animal companion that will be charmander/charmeleon/charizard. Basically all I'm doing is making it a dragon of varying size (charizard will be about .40 the size of a dragon) and giving it the no flight ability. But thats getting ahead of ourselves.

Basically if I take a Dragon, I need to edit the racial data to make him behave as I want. But even if I copy the DragonRace file exactly (new name, no changes made) it won't render at all. Does anyone know how to fix that?
