I am trying to make a hollow platform with one side frosted plexiglas and the other sides solid. I created a box, extruded it, then subtracted all but 2" all the way around except for the side I want to be solid, this I cut through completely. I made another extrude to fill this section. I want to be able to put a light in the box and have it light up the plexi side. When I put a light in and render it, it acts like the box is not there and the light spills everywhere and does not light up the plexi which I added the tecture of transparency to. Does anyone have any idea how this can be accomplished. Thanks.
