I have had this filter lying about from Flaming Pear - called Cumulous. Just thought I'd give it a whirl with all this talk :) Pic 1 - Shows the filter Pic 2 - Shows various in a pic Pic 3 - Shows these created as billboards Now the problem arises when changing an atmos. The clouds change & tend to look more flat :(. I'll assume with more time & tweaking this could be remedied.
