Quote - I saw a post by ice-boy the other day, where he'd created a low-poly figure, for personal use, by using Blender's shrink-wrap feature. He was conforming that to V4/M4 or "whoever" and then doing the cloth sim to collide with the low-poly figure instead of the actual higher poly figure... seemed like a neat trick?

Kirwyn did that, way back in Poser 5 days.  He created "proxies" of V3 and other figures, that were super low-res.  They were for dynamic hair calculations.  They were meant to be parented to the figure, used for dynamic hair calculations, then deleted.  They worked really well.

And IME, dynamic hair is something where poly count is still a huge issue, even with the latest and greatest version of Poser and state of the art hardware.  If the hair sim isn't working right, chances are it's a memory issue.
