I don't have much time to explain, but I created these clouds with POV-Ray today, they're realistic, just wanted to show off, i guess:



(Uses media, i'll post the source if anyone's interested)

No touch-up in PS? Just straight POV-Ray? ....

Damn, Sllme! I, for one, am impressed. Good show, mate.

Try www.povray.org =)

Povray has a tutorial in its help files, that's how I learned. Just go to help (in the windows version) and search for "tutorial."

Here's the source for an isolated area of clouds, which I used for that scene...

Everyone says that the docs with POV make a great Tut. While that is true, I'd like to see a big beefy walkthrough to make a halfway descent picture. That way you can learn the tools and when you're done you have something to be proud of. Thats how I initially learned photoshop (all those text effect-esque tutorials, I'd never use 'em now, but they made a great introduction)

P.S.

The clouds look great. So far all I've done is use a 2D plane to create crounds. I havn't even touched on Media let alone Heigtfields and other crazy junk like that. All my images are primitaves I'll get better though. ... hopefully. I think I'm gonna steal your source > )

That BIG cloud in the middle looks like its coming out of the mountaind like a volcano.

Here's a bigger, more realistic, and much cooler version, useable as a desktop background:

Schitzoboy, don't worry about media quite yet if you're still new to POV-Ray. Work with primitives, maybe take a look at fog. It took me quite a while to figure media out.
