Hello Tartan, Kate and headhunter - Someone asked a similiar question in the Vue Onelist. He can do this easily in Bryce...Mapping a bmp image to a plane where the background of the plane has an alpha channel, for this matter to be use as a transparency map. For the matter, I have 'doodle' up an image as an example and found something interesting. As I can't attached an image here in "reply"...please see the image illustration under heading "Mask Render" but Vue simply call it "Picture in scene" :) Bill
