Waterspout

[Dune]

Still grainy, but I've got an idea....

I have never seen a real one of these. The latest image looks quite good.

Got rid of the grain and made some fake water, which decreased render time (total 1.33 hr @ 0.5 and AA4).

Most impressive work! Looks like the real thing

Btw if I may ask... im curious how you made this.. Did you use blue nodes or did you go with the simple shape shader  + warp -route? I remember experimenting with simple shape shader and the results were something similar, but not as good as I'd liked

[Dune]

It's a set of warped simple shapes indeed. Some made into a ring, warped on the Y.
