Thanks a lot! Is there a limitation of size for multiple objects? like 0.5 in your patch? Because as soon as i change the scale from 0.5 to small cubes (for exemple 0.3) it stop reacting. Can it be they become too small for the phys to recognize them and collide? (sorry my english)
if i want a sound played with each new collision contact with the video matrix and use the @collisions 1 feature of jit.phys.world as in the jitter-examples phys.picker.impulse.maxpat file, i still get contact detections / sound with the videomatrix even if i put the tresh to 1.
