heyas; you can save a pz3 or the cr2... the cr2 is a smaller file size. however, if you have a special scene or pose you need the character in, use the pz3. you will also need to save any custom geometries the figure uses. (ie: if you made or downloaded a new creature, not for characters made from the standard ones.) you won't need to save props, those usually get embedded in the cr2/pz3. also remember your textures and stuff. :)
