I got Blackhearted's Girl Next Door 2 to replace a dial-modified V3 character I'm working with. I was pretty happy with what I'd done until I saw GND2. It's a beautiful piece of work, just like it looks to be, and I'm excited to put her into action. See Fig. A.

But there's a problem with her posterior. The pose in Fig's B and C is stock from V3's poses, and it's nothing too demanding. It's certainly less demanding than my project is going to be, but already there is a problem with the butt. From the front, Fig. B, GND2 is still total magic -- a real killer. But moving around back, Fig. C, that fantastic fanny deflates as it deforms.

GND2 needs an athletic bubble butt and I thought a thread with suggestions and results for getting it in shape might be a useful thing for the users of this model. I've just come into a bit of free time, and I'm looking to expand my skills. Any suggestions about paths of research? Is this something that wants to get addressed with magnets? Are there other, better ways of thinking about the solution?

If there's any interest, I'll post my findings here, too.
