Title: Hmmm_Doughnuts
Post by: Mr_Lamppost on October 27, 2007, 12:48:14 PM
Just a bit of silliness using a modified Voronoi 3D A vector  as a blend on some clouds.

The foreground is an eroded Voronoi heightfield.  I am not massively impressed with this :-[  OK it's rubbish :D  but the clouds are the thing.

LOL.  Cool.

[Edit] I just realized that these smoke rings are an indication that Gandolph is not for away. [/Edit]

Render time just under 6 hours on 1.8 Ghz Celeron.

2048 X 1020
Quality 0.5
GI 2/2

Atmo. samples 64
Cloud samples 48

Combining all the function calculations into a single scalar then using that as the Mix Controller for a Blend Shader, blending between a constant zero and a Cloud Density Fractal is much quicker than using the functions in the Density Fractal directly.  Found that from njen's Spotty Alto clip.   ;)

I like the clouds. Their texture look real but the shapes are crazy which is great. I want to try some weird stuff with clouds but haven't yet due to impatience at render times.

Thanks for the comments  :)

I was just messing around but there is probably potential in those clouds if I can find my way through the adjustments and blends. Who knows I may even be able to do the elusive banded Alto (Mackerel sky)  ;)

I am distracted at the moment by something VERY WRONG  ::)
