I have done a screen replacement and fed the screen graphics straight into the planar tracker. So, the node three looks has the phone fed into the background of the planar tracker, the graphics fed into the foreground of the planar tracker, and the planar tracker itself is fed into the media out node. With this setup, how can I output ONLY the screen graphic to the color tab? As I see it, the planar tracker works as a "merge" in this case so I don't understand how to output only the graphics.
