Quote - Actually, having an ERC dial controlling the xTran, yTran and zTran of the earring (possibly scaling too) fits the purpose of having one prop with fit "morphs" perfectly, much better than a morph does.
First of all, the joint moves as you intend, in a user friendly way.
Second, ERC code is far less memory consuming than morph deltas.
Third, creating extra ERC channels for e.g. Jessi or Victoria 3 is a breeze, so your earrings become more versatile, without becoming memory-heavy.

Is there a program that would make this job more, shall I say, productive, if you know what I mean?

Although I did follow JCH's tutorial on removing OBJ data from prop files (to cut down the size of the PP2 file and reference the object)  fairly easily, this whole thing sounds alot more complicated for my brain at the moment.
