You know what? SubD makes even the worst joints on V3 not only bearable, but looked pretty damned awesome. And get this - in spite of SubD, it still ran lighter on the resources than V4

It's even better when you have an actual low poly figure to work with to put into SubD, particularly if you can paint weight maps for bone influence. Dunno about D|S, just general purpose.
Does D|S have weight painting these days? I haven't at all kept up with things in the Daz-verse but I often read about all this new stuff that D|S has which has really surprised me a few times.
