Yes, Huolong! You can have moveable objects in a PP2(Prop). I for one simply use the 'Grouping Tool' to designate which part of the prop i want to move or rotate... Then just apply a Magnet(With the MagZONE Scaled 200% & Acting only on the 'Group' i previously created). Of course sometimes you have to play with the 'Centers' too in the JE. Marc
