Fully procedural cloud shader for cycles.
Simply apply this shader to convex meshes to generate unique cloud for each object. No UVs needed.

Great material! I was just looking for something like this.
The best work I've seen so far. Thanks for sharing it. I liked very much your youtube channel too.
Absolutely amazing! Thank you very much for sharing this with us. I've made the clouds with this for this render: http://contmike.deviantart.com/art/Practice-character-fanart-496323826
looks pretty cool, i did your tutorial, found it on BA i think. but i feel with the noise texture in blender, it's still looking more a bit like foam than cloud. i couldnt manage to do it better however.
yup, this one is pretty much starting point and an idea to improve. one thing you could try is to use more noise layers - for vector manipulation and also for density color substraction. good luck!
Any tips on decreasing render time? I noticed in your youtube video it was working pretty quick. It took about 6 hours to render some clouds on my 16 core server... 64 volume samples and the default 1024 step size.
well, that's a problem for sure. you say step size, but i understand you meant step count ;) using bigger step size will actually speed up your renders a lot, but will also dramatically reduce details. how to improve? couple things you might try: - branched path tracing (wchich i assume you already use, but what many people miss is that you also set bounces and samples per light in the scene); - use clamp setting for direct and indirect rays; - don't use too strong lights, in fact, use only sun for the key lighting (with low size for better details), of course with multiple importance on; and probably background for fill lighting; - use as few glossy, transmission, sss shaders as possible, turn off caustics etc; unfortunately i don't know magic tricks for volume rendering ;)
This is great, thank you
Looks so realistic!
Is there a way to make them look alive (animate them)?
Of course. Depending on how you randomize the noise. In this example it was based on object's position as far as i remember so you would just add to the vector position of another object (like empty) and animate this empty' position around scene.
Great blend! Very nice results and indeed very low on memory ...
thanks for releasing this under cc-0, but if we wanted to credit you how would you like us to?
Well, in that case nickname and youtube link (description) would be the best way, since it shows whole process.
Thanks for sharing this! Used it as a base to create the clouds in my short film: [https://www.youtube.com/watch?v=VLgHulH9NFY](https://www.youtube.com/watch?v=VLgHulH9NFY)
WOW.thats great. I'd love to see the blend Files of the amimated clouds. I tried to achiev sth. simmilar but im totaly stuck. Is it possible to send me the File for learning? Best Regards
Looks very realistic!!! thank you
This is Great! Thanks Kilbeeu
Looks very well done ! Thanks !
CUDA Error.... This video card are very good. Or no?
which CUDA error? these tend to have more information attached. out of memory one? more ram on card required to contain complexities of scene. tweak global illumination values.. reduce the amount of geometry.. procedurals are typically computationally heavy and require a lot of ram. Baking back works in many workflows, doubt you could apply here though.
so beautiful.
Thank you for this! Coming to the background of a GIF near you.
OMG those nodes are giving me seizure. I'll never be able to make something like that.
Very impressive and very realistic !! Big thanks !!!
My clouds are coming out dark gray rather than white...is it my lighting? Or is there something I can tweak in the shader to change the cloud color? Thanks! Bryan
bcgreen24 - I had the same issue at first. Look at his example project though. Set your lighting to emission under use nodes (I use sun then hemi to 'tone' them). The person who created this project set the strength to 7. I personally used 10 with the 'tone' colored lighting (a nice orange and yellow look nice!) set to a strength of 3 with great results!
I knew exactly what I was after would be here! Thank you very much kind sir! don't worry.. I won't bring silly questions like ^ I"ll just troubleshoot em myself.. (bc.. does the shader contain 'emission shader'?, if so tweak there. yes it's probably your lighting, though it may be your hardware or your current blender version revision. These questions are problematic as they have the reader arrive at multiple avenues to the power of many. Stay awesome everyone!
Can't download. It's just a *.html file
any tips on lighting?
Marvelous! I'm going to use this in my project
Awesome, thank you!
one of the best clouds I have every seen in cycles, cool, thank you!!!!
Excellent work!
