What version of Poser will this require, if any?

Here's the thread where cage posted his subdivide script. I've used it a few times with success. I quite often simulate relatively low-poly meshes in the cloth room, for speed, and then subdivide afterwards to iron some of the wrinkles out.

Edited to add: cage admits that while his script implements subdivision, it isn't a complete smoothing solution. Hanging around to find out more, in any case.
