You cannot move a morph because you do not have to. The morph is already there. You just do not see its dial because it is hidden. Make it visible and you have what you want. You can then delete the dial in the body actor. The only thing the dial in the body actor does is take and hold your input.The parameter (dial) in the head actor 'knows' it has to get the value from its 'master' parameter in the body actor and add it to its own value setting before working its effect (= move vertices around)
