Recently I had the idea of using cloud layers in a different way. Here I animated some localised cloud layers with different densities and differently animated cloud fractals to simulate a mighty avalanche. I used a fill light setup to get rid of the GI flickering. No postwork except the subtle camera shake in the second part. Hope you like it.

Holy shit. Glad it's not real. Looks scary realistic.
The only thing needed is some displacement of he snow right in front of the slide. It really is quite awesome. Fantastic.
very realistic !
the avalanche looks a bit grey sometimes but holy crap, that's a good one !
Mwoah, yeah!
Absolutely loving this!
I agree with Franck, at some points it's a bit grey.
This deserves higher res and quality, very original work. Oshyannnnn...? ;)
Cheers,

Wow, Hannes! Looks extremely good! :)
Superbe, bien fait.
Wow, that's very impressive. Surprisingly realistic for not having a particle simulation. Nice work!

Thank you and merci beaucoup! I agree that the snow looks a bit grey, but I decided not to use a completely white colour for the snow, because it looked kind of washed out. Additionally the conversion of a QT with best animation (codec) settings to a H264 to make the file much smaller creates some kind of a low contrast.
I wish I could have rendered this one with higher quality settings, but as you can imagine, renderings with this amount of clouds take veeeery long to render, and since I don't have a killer computer I decided to reduce the quality settings a bit.
AND I'd love to animate the trees, so that they are bent by the snow wall!!!!! But I didn't succeed so far. Maybe next time...
WOW! Very nice , Hannes :)
Wow, that's insane, man!
Holy smokes! Thats a very impressive animation! Good work!!
RUN!!! too late. i got clobbered.
!!!! :o !!!!
that's incredible hannes!
the end of the video was my favorite part, i also think it was the most realistic part too,
Great work! :o
fantastic work!
utterly gobsmacked!!!..... wow,excellent work Hannes!
bien joué fantastic work.
The avalanche effect is really good.
Really good job.
Incredible!!!
How did you get the front bump shape of your cloud PFs? Did you animate the radius of the localised cloud? There looks like there's some warping/scale stretched noise in there too.
Very impressive.
I didn't animate the scale, but there are three localised clouds that are the "leaders" of the avalanche. I simply animated the position of them and stretched the cloud fractal by a factor of 2 into the direction they are heading to, but I didn't touch the warping.
The cloud fractals are animated by a transform shader down the y-axis and also a bit into the direction of the avalanche, but not very much.
There are also two bigger localised cloud with different density and noise settings additionally to the three mentioned ones, which are stretched differently.
It took quite a while and a lot of testing to get the motion and the speed of the clouds right.
I hope this makes sense, but I don't think so. That's why I decided to share the file in the file sharing section. Play around with it and have fun.

totally agree...only thing other than a bit of front avalanche snow build up would be collapsing trees as the snow/cloud covers them...but really well work'd out...KUDOS.. ...
Very convincing effect indeed! I am impressed.
I kind of agree with bobbystahr on the trees - you would see the trees tilt when hit by a small avalanche. But in a bigger avalanche the pressure wave in front throws up so much snow dust that everything else is invisible.
Wow, this is very impressive!
