heyas; i think it looks like the surface of water, rather than clouds... kinda. :) but very neat. save it! mike mike mike... i'm sure you've seen my puffcloud vue tutorial, as featured in the renderosity vue tutorial database. ;) (at least... i THINK it is still there!) basically, its a lotta stones... lower edges, if you like, trim... they look better if you squash them along one axis. then the puff cloud cloud and air mixed material. i dont put puffy bottoms on, i just let them fade out before they get there. :)
