I've been trying to create a beer simulation with foam, although when the cup moves the particles collapse in on themselves and fall out of the bottom of the RBD object. There doesn't seem to be any problems when the glass gets filled up, just when it starts to move. I thought it had to do with particle separation and sub-steps, but that doesn't seem to be the case. Any help would be appreciated!
