Hi.
I’m trying to create a kind of fountain using coins attached to individual particles. However, it seems like there is no kind of self-collision going on as the coins do not pile up as expected but rather just lie on the floor-plane.
I was under the impression that the particle system actually did some kind of self-collision but does that only apply to cloth and hair?
Finally, what should I do to get the coins to detect each other properly? Is there an entirely different technique?
