Thanks this helps a lot. So I would create regions, in this case, one for each leg, arm, for the toso, and head, so 6 regions, with two permutations per region, one being non-damaged the other being damaged. The max files will contain just the geometry of said permuation and the bones for that permutation, or will the max file contain the geometry and all the bones for whole biped? Correct me if I am wrong.
