I read that you can change hand positions through morphs....defaults being relaxed hand, closed hand/fist, peace hand.... my question is, how do you apply those to mesh hands? If I make a mesh glove, will it's finger go into a closed fist if i'm holding a sword? Or do I need to make multiple hands in their various poses and make a hud that switches between them? Last question, is it possible to make your own hand morphs? Thanks in advance
