Thanks Luke. I am from the same group as kiddou and also a beginner in max. It seems that jit.gl.multiple generates many video instances but we would like to be able to affect each bubble generated (as the bubbles will be of different sizes depending on the amplitude and each bubble has to move). Attached is a prototype of our patch. Really sorry if its super messy , the bubble part is in p mouthtracker. Really appreciate the help and thanks a lot for being patient with us.
