Just out of curiosity, what are you modifying with this file? I haven't finished with it yet.
Made some changes to the textures to make it less demony and more monsterish. Seems to be working pretty well now, though it obviously needs to be slowed down a bit, and needs a walk animation. It also sometimes seems to sink into the floor a bit from time to time, not sure why. First is the original D3 monster, beside that is the TDM version.
