Quote - Poser doesn't support Sub-D.  Poser uses trianglization to acheive smoothing.  Againhttp://www.subdivisionmodeling.com/page2.htm

However Poser achieves smoothing, two things seem to be true of it.  One is that the fewer polys in the original object, the less the smooth object will look like it.  The other is that the smoothed object does indeed have more polys.  I've seen broomsticks turned into beachballs, so there is certainly something going on there.  I tried not to imply that it was the same algorithm as Studio's, but I'd certainly call it a method of subdivision as the rendered model has a higher poly count than the working model.
