Blue/Green Screen for video
I would like to do some blue screen compositing with different types of video. Such as adding a ut2k3 character in to a video of a different game or a home video.
My question is- How would I make a map that had no shadows and is the same color of blue (or green) no matter where you are looking?
I have very limited knowledge of mapping. I have opened the editor, subtracted a cube, made the walls solid blue. But when I add a light, there are shadows in the corners/edges and the color of the walls is not uniform. Any help is appreciated.
