@kirsten said: @dbiniThank you. I'll give the effects mixer and 3d particles a try!KirstenI find it can be extremely interesting to daisy-chain Effects Mixer actorss together (making some adjustments here and there so as to create more differences between the video feeds).Sorry for the lack of labelling (I was in a rush).Play around with this Isadora patch, or have your students do so.Best wishes,Woland
