(blown) Snow on ice shader

Just made this quickly to incorporate into a scene I'm working on.
It's a watershader with a density function, followed by a surfacelayer which adds slight cracking.
Then the snow is added.
Pretty basic, but still 23 nodes already...

By the way, the red thing is a 1m sphere to asses transparency etc.

Cheers,
Martin

good work but I think the ice needs to be more reflective.....

Yeah I was a bit in doubt about that already. It's at 0.5, so I'll try 0.7 for starters.
Thanks :)

you'll not get that ball back before spring!
nice to see higher res when this is completed!
keep up the good work Martin!

Here it's partially in action in a small crop of the image it will finally be used in.
I inverted the crack profile, because I just find it cooler :) lol
Dhaval, the reflectivity is 0.1 here. Still pretty reflective I suppose. What do you think?

dhavalmistry

yes its weird.....I guess we miss the blur reflection feature....but its looking very good

It's not that weird I think. The first image I posted has a camera facing downwards, as the latest crop faces a bit upwards.
This hugely influencess the result of reflections.

With some snow...getting somewhere now...


dhavalmistry

oh that extreme displacement is killing my eyes and the image ;)

coming along good....the snow still needs some "wet" look....and perhaps some specular highlights on ice?

Really convincing, looks great. I like the edge blending of the snow layer on the flat ice. Cool!

Ghehe yeah...you caught me there...occasionally these show up unfortunately.

I'll see what I can do about the speculars. The surface is quite smooth and lacks rough features which would facilitate specular highights.
I even doubt if blown snow would have such a wet and shiny look, guess not.

Fun thing is, is that I got smooth patches like in my very first picture, but that those patches where displaced as well by the cracks.
So I inverse blended the voronoi with the PF which makes the patches, adjusted the breakup and coverage a bit unusual and then this was the result :)

Daannnng! Those last two are awesome! I love the lighting, shading, and reflectivity. Too bad about the exploded geometry though.

Looking really nice, aside the exploded geometry. I know what you're doing this for and I think it's a good idea. ;D
