Shrinkwrap Modifier on the same Object

Is there a way to use the Shrinkwrap Modifier so that it “wraps” on the same Object that it’s being applied to?

For instance, I have this model (Harley Quinn, from the old Batman cartoon), and when her tits grow or move, they overlap on her collar, which is a separate Mesh. If they were separate Objects, then the Shrinkwrap Mod would be a good, simple solution.

But I can’t think of any clean and simple solution where they’d stay the same Object.

It would be great to see the Shrinkwrap Mod enhanced to allow this. In the meantime, does anybody have any suggestions?


For skintight clothing like that, I personally wouldn’t even model the clothes as a separate mesh in the first place. It’s just a waste of polygons. I’d just delete the skin layer and leave the clothes.

No, no, no: The clothes AREN’T a separate mesh. Only the necklace is.
