In the intro is andrew he can walk and do most of the things i want a puppet to do. Can i edit his appearance in Photoshop , rename him and use him while keeping his behaviors and other settings?
Yep! If you twirl down the project panel folders on the left, you'll see a few different instances of the Andrew puppet (he has a few variations on him depending on the scene). If you select one of these puppets and go to Edit > Edit Original, you'll open up the original PSD. Make any changes and save and they should sync back with CH.
