Isn't there some way of MAKING such a mask in PhotoShop? From the 1st render? I know how to do that in PaintShop, at least I can see how to get an image with black everywhere except where the object is, and there you could just reverse the selection and paint white in that shape, result - black with a white blob the shape of the object... but I've never used photoshop, so I dunno where any of the tools are or anything. IF... IF a black background with a white object shaped blob is all we are after for this stage. Is it?
