Oh, forgot to mention to make sure that in a multipart prop that you are parenting the exact piece that is parented in the main screen. For instance say you've made an earring which has four parts. box1, box2, box3, box4 these will be identified by the line name box1 name box2 etc. It's the one with name box1 that you will need to edit. All the rest will already be smart parented. Hope that helps
