There are 2 actually! one being the manual way by just assigning them in Milkshape. Then there's the Meshtoolkit way, where you bascially fool the tool in making it *think* it's clothing but in reality it isn't. To do this, you want to merge whatever group you have, except for the shadowmesh (Just delete that one) And change it from 'group_0' into 'group_base'. Same for the reference mesh Then just only use the bone assignment tab and there you go!
