While at the time this thread was created BodySlide was kind of "meh" past a certain point, it has made great strides and the new version - BodySlide CB++ - Is pretty much anything you're looking for to start shaping the bodies you want. It comes with a lot of compatible clothing now too.

As for this recent update...It's very cool. I'm in love just for adding color silders. Thanks!
What it does work with, as said above, is a body and/or armor mesh that has been weighted to the skeleton at the correct points. For example, this was edited with bodyslide - Weight/height and all work fine as usual, but the individual bones do not.

What this mod seems to do is edit the scale of nodes on the skeleton just as if you were opening it up in nifskope, so all of the previous requirements I mentioned for the manual method apply.
Scaling the butt or breasts past a certain point on some models will look pretty dreadful.

But others work with it pretty well!

If your armor or body jiggles, then it probably works. As much as I just praised CB++, most of the armor files I created with it don't have that bounce. Conversely, the TBPP body/skeleton/CB++ created mesh works with it fine (though if you set the breast scale past 2x it starts getting messy as seen above),

And Ravensaw's armor (which I plugged earlier in the thread) is also compatible as seen in one or two of the screenshots.
