In order to take advantage of a smoother contour on the figure, the subd should be reset to 1. However, Poser does have it's own subdivision by converting the figure to Poser unimesh and either changing the subd in preview or during render. In this case, the subd'ing can be pushed up as high as 4 depending on your system. I can push it to 2 on my system, but Poser will post a warning if I go beyond 3. Resources can take a tremendous hit.
