Clouds/Volumetric Light in Cycles!?

Hello folks!

I scourged around the net trying to find alternative methods to get clouds and volumetric light in Cycles, this is regarding an animated scene and I intend to have moving clouds in the far distance along with the sun shining through as it passes by.

I tried by forming planes after a cloud like texture, but it just didn’t look right… So, I need some guidance to get me on the right track on how to deal with this.

Thanks!

Hi,
I am trying to do a similar thing but I have to be able to look at the clouds from above. I have cheated with a layer-solution using one pseudo volumetric node-setup. In your case I believe you could use the same technique but put the layers in a camera facing direction. If you are interested in my setup I can post it (just don’t have it at the moment).

Ok, this is not very pedagogic since I have not built this very easy, but anyway you can probably see how it works. I have a gradient map of a round cloud (my cloud test to see layer etc). I have also created a mapping that allow it to get changes over the depth.
With the output from the mapping you can use a contrast node to “scale” the feathering on the cloud. In that way you can build a cloud that is spherical in z-axis, but any shape in x-y axis.

I’ll try to show it all in this image. If anyone has better solutions I’m up for it, please. A volumetric node would have been nice.


Cheers

Interesting workaround! The results you manage to get would be very interesting to see!

I just got back to my main PC, and I decided to just do the clouds and all that in BI then figure out how to slap it over the cycles render! I read something about having Cycles and Internal rendering on different layers, but I suppose that is just wishful thinking! :smiley:

Hi again,
Here http://www.blenderartists.org/forum/showthread.php?291644-Space-Earth-volumetric-cloud-shader-rayleight-scatter-etc
is my work in progress using the technique.

I have actually tried that blender Internal/cycles with different layers, but its a nightmare if you want to change things (having 2 material setups

Counting can also be in the attitude of enumeration marks, making a device for each number and then counting all of the marks when done tallying. This is advantageous when counting objects in excess of time, such as the compute of times something occurs during the speed of a day. http://rhueldenth.org.pl/?p=6296http://residualincomecoach.com/2010/send-out-cards-make-a-living-through-giving/?replytocom=3232http://residualincomecoach.com/2010/send-out-cards-make-a-living-through-giving/?replytocom=3656http://instalatorstwosrodaslaska.pl/notariusze-w-krakowie/http://sprzedazmontazoponzory.pl/tag/notariusz-w-krakowie/ http://krawiectwomargoimielin.pl/category/rozne/http://serwisholowaniepodkarpackie.pl/tag/notariusze-w-krakowie/http://losethefatandgainmuscle.com/lose-a-dress-size-in-an-hour-and-be-back-at-work-the-next-day-at-final-inches/?replytocom=25645http://market-zoologiczny.com.pl/tag/notariusz-w-krakowie/http://wendyduncan.com/articles/mitigating-stress-in-the-workplace/?replytocom=314
