Up-to-date Guide for working belly bulge?

[atznk1ller]

Does anybody know about a recent guide, mod or even combination of mods that give you the opportunity of a working belly bulge? I only found guides that are more than 2 years old, and i'm not really sure, whether they still work/are compatible with today's skeletons
That would actually be really awesome if somebody knows about something like this

I use PSB body and "it's just works"

 

Although it's very old, and most likely not going to work with most recent mods

The all in one body around here someplace does exactly that.
