Glad to be of help, Kitty.

Perhaps these images, casting shadows on a curved plain will demonstrate more clearly for anyone following this thread. With the light parrelel to the ground (even with quite a wide light cone) no shadow is cast, but with even a slight downward tilt a shadow starts to appear.

Poser shadows are offten a problem, and I have yet to meet anyone who understands them fully, I certainly don't. Nance and Little_Dragon probably know more than most.

Here are some threads touching on shadows:
