Ron, Thanks for the hints. I did the parenting to the head part. After that I opened the prop librarie and saved it, but it never asks if I want to save it as a smart prop... What am I doing wrong? The only thing that pops up is the window where I can put a name for the prop and an option that says "select subset" there I can select the hat and then klick ok and it is the prop menu... Caro
