I already did, none of them really helps.  I can do the dynamics just fine.  The main problem is when I pose my figure in a flying pose, the shoulder part of the cape do not follow the collar of my figure, it ends inside my figure.   Like I said before I want this part to move with the figure's shoulders.  I applied the choreographed group and constrained group on the shoulder part of the cape.  However the cape either falls off (It is parented to my figure's chest) or the shoulder mesh gets messed up. Not sure what I am doing wrong.  (The cape is a prop)
