Yeah, lame title I know.  ;D It took more than 94 hours, mainly because I had to turn the acceleration chache off for one of the cloud layers because of banding. C & C welcome.

Really nice, as always ;).  I think a little more warping in the larger cloud banks would be appropriate, but the small-scale clouds really bring out some nice detail :).

This is nice.  I appreciate your work on these a lot more, after having attempted to do it.
So this is Disney World.  Can we live here?

I second OB's suggestion....but dont you think the smaller scale clouds are a bit on the rough side???

nice work anyway!

Yeah, at first I thought the same thing that you did dhavalmistry. It's hard to get that sharpness that I need for those small cloud (to help add detail) while keeping the softness they need over mutiple altitudes to still look like clouds. I think I'm going to try to soften those clouds up a bit on my next render. After looking at literally hundreds of satalite photos I have seen clouds that look just like that though. OB, I also agree that the cloud could probably benfit from a little more warping. The trouble with warping is that it has to be unified throughout the cloud layers. While I could have warped the clouds for this specific render, the cloud setup is meant to be used for renders of the planet from far away or close up like this one. So basically, while I want the clouds to warp, I also want the warping to be logical between layers -- and that's the hard part. And beside if I changed the clouds just for this render I always feel like I'm cheating  ;D. Thanks for the comments.

Creating convincing large-scale weather patterns is tuff stuff. The only application that i know of that handles such patterns is a Photoshop Plugin called LunarCell but these procedural patterns look like crap 90s quality graphics, the small-scale patterns are very basic and these Plugins are in need of serious updating. They have potential but development is more or less slower then molasses.

The basic large-scale idea of global weather patterns is there but that is all there is.

I understand your reasoning about the warping - many of my projects take significantly longer than they would if I just "cheated" because I want to develop a technique that I can use over and over again.
