I've tried searching for a solution to this on the forums but haven't had much luck. Apologies if it's been covered before.
Basically, I'm getting very severe popping on one of my clouds - it's a very large one, it's quite thick and dark. I've included a small quicktime to show the issue as well as the scene. Any thoughts on which way I should steer to solve it wold be HUGELY appreciated.
P.S. in the .tgd file it's the one called 'MASSIVE'
