Hello,
I'm starting to have my little cloud collection covering lots of cloud type, and I have to say terragen atmosphere model is really awesome.
But I have some hard time to archive windy clouds ... and off course I have tried the obvious, like the embedded fractal warping, or a fractal warp shader.
So here's the kind of cloud I'm looking for.

From my test, warping solution seems to blur the cloud way to much (I really try to get long fading trail), and failed to keep definition. I also tried to overlay twice the same cloud, one with warping, but without any good result.
I know it's a very vague question, but if anyone is kind enough to give some tip, or idea about how to proceed, I will really appreciate !
