Ditto-ing what Ricky Ramwolf said above about strappy type items. I've had trouble getting workable conversions of suspenders, belts, army soldier chest straps, skimpy bikini bottoms and tops, that sort of stuff. They usually end up looking crumpled.

Also maybe I've just missed this somewhere on Phil's site, but I'm not sure I understand what smoothing by material is as opposed to standard smoothing options.

But this program is really my favorite Poser "add-on"
