yeah. The function is listed, but no reference to use it after you call the function.
I am guessing your model would only be rigged, and the LoadAnimation(entity, path) would have to be an single animation file, you couldn't load a different one for each sequence you want, because Animate(frame, blend, sequence, recursion)...?
My question, does LoadAnimation() override or append any animation that may be currently set in the original enitty?
