Yeah however, it is a problem with the bryce render engine. Most renderers have the ability to use unbroken phong shading. Which in essence smooths the face of the object much like bryce's "smooth' option, which does not alter the geometry. Most have this ability up to a certain angle. bryce's angle is just FAR less than most apps, thus this occurs. That's why when you chose to smooth to a certain angle it will smooth it likewise. If the angle of the polygon to the adjacent polygon is greater than the smooth angle, it will render broken as seen above.. However sometimes this doesn't seem to work...
