View Full Version : difference keying?

is it possible to use the difference blending mode in the texture editor, and use it to key out the difference. i took two pictures shot from the exact same position(with a remote) one with me in it, one without. then i blended them with difference mode, and saved the results, which appeared to be the difference, i then applied the difference image to a flat poly(or the background..i can't remember)and set the rerdering options to save alpha.the resulting alpha was completely black. so is there a better way to go about doing this. i would like to apply this to moving footage eventually.:shrug:
