I was using GEM already and that was my original problem, because I wanted to have multiple GEM windows open to show all 3 Cam's at once in one instance of PD .. <br>I'm using the webcams to detect motion and supply XYZ coordinates to a scanned synthesis patch ... I've attached a shot of the motion detection patch to make things clearer ..
