In my flip sim, I used the white water shelf tool to add foam, spray, and bubbles to my sim. The foam and the bubbles are functioning as I would expect, but the spray has strange behavior. It seems to be confused to as to whether or not a particle should be foam or spray. This results in spray particles getting stuck and not moving for a bit. When the particles become spray, they go from white to green. The faulty particles go from white to green, then back to white and back to green. It looks like they pile up against the floor (starting around frame 30), as show in the photo. I saw that someone had the same problem here: https://www.sidefx.com/forum/topic/45041/?page=1#post-201381
The fix the guy posted at the bottom did not work for me. Does anyone have any other ideas?
