Quote - Basically I suppose for the added convenience to the user for having those dials present in the PP2 file is that you're just going to have to open the Joint Editor window and move the joint to the new location for either earring.

I think you are missing the basic point here. If you move the earring via translations, as opposed to morphs, the user does not need to "move the joint to the new location" because the 'origin' (center of rotation/joint) stays in the same place relative to the prop. In the example attachment, the centre of rotation is in the center of the prop when the prop is parented to V4.2. It is still in the center of the prop after the Fit_Girl dial is used to fit the ring to The Girl.

Really the center of rotation should be at the top edge of the prop, not the center, but that is just a detail that I forgot to fill in, because I was illustrating the ERC code, not the correct position of the joint center. If the joint center had been at the top of the ring when it was parented to V4, it would still have been at the top of the ring after the dial was used to position it on The Girl. The whole point is that a positioning morph is worse than useless in these situations. Scrap it. You don't need it. Position the rings with the translation channels as described in my previous post. The user does not need to change the joint center, because it stays in the same place relative to the prop, as long as you don't use a morph to move the prop. Try out the example I posted, and see for yourself.

For a small and simple thing like this, I find a good text editor, like "EditPad Lite" quite sufficient. For larger files that would require a lot of scrolling in a text editor I use the free "CR2Builder". There may be other tools out there that you could use, but I do most of my editing in the ones mentioned. Dimention3D's "Poser Power Tools" and "Poser File Editor", and PhilC's "Poser Tool Box", and Ajax's "EasyPose Underground" are probably worth looking into, but I don't use these myself.
