Hi guys, I havent had time to finish this or even work on it, not sure when i can get to it next but here is a Cal3d loader i was working on, currently i believe i was at the point of trying to weight the vertices to the loaded bones , but i had problems doing that at runtime.
Anyhoo here is the code thus far
