Spot light shows dimly through solid plane I'm attempting to shine a spot light through text that has been cut out of a plane. The effect works pretty well, but some of the light from the spot light that is behind the plane shows through as seen in this picture:



The plane uses default settings and has no material or texture associated with it, though adding a solid black material has no effect on the render. 

Lamp is set to Spot, Buffer Shadow, Halo, Step=1, Distance=10, Size=130.  Other settings are pretty much the default settings.

I've been playing with this for hours and can't seem to figure this one out.  Any ideas?

Thanks!
I think is the blocking object, it's 2D. Try to get another one starting from a 3d even slightly extruded plane (extruding your gives me weird results), carving out the text. Then you might need a slightly more powerful (energy) spot, but in this way I got it working.
