You would not see this if you were using P5 with smoothing on because P5 actually smooths the geometry with micro-polygons - Poser 4 will not smooth the geometry itself, it will only smooth the shading, so you still see the geometry shape when in profile. If you want to stick with P4, the only solution is higher resolution meshes for the figures. In the long run I find it much cheaper to upgrade to P5 (than to buy more expensive firures), then ALL my figures render as if they were made of 100s of thousands of polygons - much higher even than the 3rd gen Mill figures do in Poser 4.
