ahh!! i think i know where this is getting at! :) you mean like a wall and a ground combined? so you can add a texture to the prop and can cast shadows on it? hmmm...extremely useful for composites right? so instead of layering your shadows in APS you can directly cast shadows on your prop provided you have the appropriate background texture....hmmm...pretty interesting..... does anyone have renders using this product? please post...i wanna see this in action....thanks in advance!! =)
