Try making a plane that is perpendicular to the camera, then give it your
background color, an ambient of 0, and a diffuse of 1000 or so.  This will
give a plane that is your background color over its entire surface except
for where it is shadowed, where it will be completely black.  If you need to
add transparency to the resulting image, add it in an external program.
