Clouds fast to be rendered, totally procedural, non volumetric.

actually this is an old technique ( ver2.51) , allows greater control over the distribution of clouds, but should be reviewed to optimize render times
Wonderful! But how do i make clouds of my own out of this? (Or modded clouds.)
That's truly impressive. Though I cant get it to render looking nearly so good, must be a 2.49 thing.
