HDT, figuring stuff out

[Advint]

So I was trying to figure out HDT, which all in all is easy to get working, but getting it working right is the hard part. The thing I ran into is the breast compression, where with animations from sexlab the hand would crush the breast. As well with some armor I had which didn't appear to have TBBP properties the breasts would be crushed by the mesh, and even after I fixed that for a few of them the mesh would not sway.

In short, how do I modify a mesh in bodyslide to be TBBP / HDT compatible, and how do I make it so the animations won't make physics wonky.
