Get the Felimage plug in. It allows MUCH more fine grain cloud effects.
How Do I ??? - Make realistic polar caps using GIMP's noise and fractal features?
Hi, complete newbie here.
I have been attempting to create a planet texture in GIMP. The "Filter > Render > Clouds" options seem pretty good at making sparce continents and islands, but after struggling for a couple hours I am forced to admit I haven't got a clue how to make realistic polar caps. I'd really appreciate if someone could give me advice on this.

Thanks for being helpful, but this isn't quite what I meant. I guess I need to be more specific.
I am making these textures for use in a program called Universe Sandbox, which takes mercator projections and maps them onto spheres. As a consequence, to render my polar caps I need white areas at the top and bottom of the image with a fractal-looking border, which gradually have less white the farther they get from the top and bottom edges, but do not lose opacity, only size and frequency of white areas.
