How do I make a whirl cloud?
I am thinking about a planet view from space where something like a hurricane should be visible. I understand that I need to apply some kind of shader to my cloud cover, but which one and how? In the easy cloud window, I have tried to apply some of the transform/warp shaders by means of the "Mask by shader (BETA)" field. But when I do this and render, my cloud cover simply disappears from the image altogether. So this is obviously not the right way.
Does anybody know a solution?
