Preserve Volume With Skin Weights

No.524347 ViewReplyOriginalReport
I exported the Daz3d Gen 3 female character to look at the skin weights in Maya. I've never seen volume preservation like this before with out fancy blend shapes or something but it seems like they did it here with only skin weights.

How did they get the weights so perfect and how is the bottom keeping its volume when bent this way?

In my image on the right you can see a normal smooth bind and on the left is theirs. I've tried painting over their model myself but can't get the same results. The butt always collapses.
