Quote - The same would apply to the adjustable prop.  (Two actions needed.)

I can think of a Python way to make the process fully automatic, but it
would depend on the target figure having the right name, and it would
be fooled if the user had renamed his Vicky.

Perhaps a better way to describe this...

The pivot (joint; joint editor)) point that you have initially set at the top of the earring prop where it meets the ear of V4 stays with the object as you turn (or enter 1 in the data entry field) the dial at the top of the earring when it meets G4's earlobe. The pivot point would move along with the prop's morph.

I guess what I might also be suggesting is there somewhere in the PP2 file that states the pivot point (JOINT) location when you load the prop. If so would there be a way to copy that so that the pivot (JOINT) parameter is also at the top of the morph 'earring' (object) so it keeps everything in one file for ease of use.

I hope that sounds right.
