#SHADOW casting quest
So I was wondering about casting shadows in 3DS. I have a tube with
the ends cut out. I have placed a blue light in the tube and placed
the target ust inside the end. I then created a "wall" and placed it
a few feet from the open end, infront of the light. The light is
blue. The subsequent rendering shows that the wall is all blue. Why
is that? Shouldn't the tube "cast" its own shadow and made a round
shadow on the blue wall? I know I can just reduce the falloff/hotspot
to the size of the end of the tube and get the same effect, but I
just wondered if an object can cast shadows from the inside out?
