heyas; you can get pz2's to store any setting in the channels section of the cr2. (for body parts. materials aren't body part channels obviously, so i dunno how it notices those, but it does.) non-channel items cannot be applied via pz2s. (i tried making hand library entries that change the visible to 1/0 on all the hand/finger parts. no dice.) when you are creating scaling pz2s, keep in mind that if there are several scaling variants for your object, you need to save the scaling info for bits that dont change in all cases. with hair, once you stick it on a character, you're not likely to want to make the hair big again (it wouldnt fit). on my hawk/falcon species poses, i had to make sure to save the non-changed leg scaling channels, in case the user wanted to switch between a bird with scaled legs, and one without. also note that because the pose files use the key values, when you hit restore figure/element, they will revert to the pose-applied values, not the default load-in values.
