YES! Very impressive clouds! These are from a plug-in by Dmytry Lavrov. More great looking cloud renders are on his web page-- see link above: From his website: The "clouds" can be used for planetary atmospheres, clouds, mist, fireballs, etc. The camera can fly through clouds , clouds can intersect with surfaces, etc. Everything can be animated... "My main research interest is efficient volumetric and isosurface rendering"
