Greetings, does anyone know of a way you can create clouds on a object or somehow distributing the clouds in a planets rings like the image below.
If you use the search function you may get lucky, as there are several attempts at this, and some very succesful. I think there are also tgd's around.
Short answer: A mask.
Longer answer: Depends on the orientation of the planet, but assuming you haven't rotated the planet you could mask on y-values alone.
Something like this?... I suspect you may have problems with noise (thick cloud layer, very low density) which may not be a problem depending on the effect you're after.
Here is a thread has lots of talk on the topic:

Start at page one there are a lot of problems that you can run into, but it works in the end.
