I think it was V1/2 that wanted props like this parented to the collars. Even so, if you moved the collar in any direction after parenting, the props needed to be realigned. Does this work the same way with Antonia or say V4? Even enlarging or reducing the size or shape of the breast it would have the same problem. Really frustrating. What would one do if doing an animation and say nipple tapes or barbarian breast armor similarily parented needed similar realignment?
