Doesn't seem to work : I was doing a quick image mapping to an analytical rectangle with no good results , and after mucho head scratching , it appears that this is impossible .
What threw me was that the OpenGL rendering was per- fect , but it would raytrace 'black' . Nurbs rect was fine , and SDS rect default mapping was fine , but for the analytical rectangle I had to apply a parallel mapping in order to get the material to show up . Weird . studio
