This really, really cool, dandel0! The falling snow is excellently done. Never seen anything like it, so get yourself another computer and render away at a long movie...

I beg to differ, Ulco. You've actually played with this method yourself to some extent. Remember this thread from late last year that Falcon started?
http://forums.planetside.co.uk/index.php?topic=8099.0I no longer have the .tgd that I uploaded to page 3 of the thread but as far as I remember, it's much the same setup here as I used there.
The main difference in this animation is that the cloud layer is much thicker and begins(base altitude) above the mountains. This layer's base altitude is dropped to beneath ground-level and a seperate fractal blending shader supplies complete coverage and warping throughout. The warping ranges from '0' in the first frame that contains snow(frame 100), to '1' in the final frame(frame 300).
Other animated parameters are as follows(from/to);
Sky cloud layer - Cloud depth(10 / 50), fractal coverage(0 / 1), colour(0.35 / 0.1), scattering colour(0.35 / 1) density(0.01 / 0.025), fake internal scattering(0.25 / 5) and warping(0 / 0.5).
Flake layer - Fractal coverage(-1 / -0.75), layer altitude(3500 / 2000) and density(0 / 0.01), the blending shader to this layer has the animated warping controls(0 / 1).
Snow shader surface layer - Coverage(0 / 2) and intersection shifting(0 / 1).
I think that's it all.
