I know very littel about moddling, but wonder if the easiest way might be to add the jewelry to the collar groupes in a renamed copy of the V3 obj file, then use a copy of the cr2 that pointed to this obj. Of coures the standard morphs would on longer work on those groupes. Just a thought. Another idea. If all the deformation in the collars is based on morphs made with magnets, then it should be posible to include the jewelry as deformTargets (Add element to deform) when you make the morphs. Then you could spawn morphes in the jewelry and slave them to the morphs in the breasts using ERC. The problem with this idea is that any bends of the collars due to joint rotation may also throw the jewelry out of alignment with the breasts.
