Hey all,
I was trying to create a snow material that would render fast and look somewhat OK.
I had a little fun while tweaking it. :) Models are just placeholders to preview the material and also textures are too low. But that's not important atm.

Looks a bit like plastic but a good attempt.

Thanks.
You think? Yeah, probably need to tweak it a bit more. There's a thin line between plastic and snow. :)
But I kind of like the crispy look like on a very cold day.

I don't think it looks like plastic, it just lacks details that is all.
Snow is reflective anyway, so he's in the good way.

Suv, did you try to generate a perlin noise, maybe 1k then create a bump of this? to get the snow sparkles.

Good idea!
Atm I'm only using the turbulence procedural to control the roughness value.

Not sure if this is fast enough, but you can use SSS with the specular roughness value at like 0.8, then set absorption to a color like this (#FFBF40). Snow and ice absorb/scatter lower wavelengths like red and yellow which is what makes it so blue at large amounts.

A faster version might be to blend your glossy material with a diffuse material with transmission set high (probably all the way at 1.0 will be good) to simulate light coming through the snow subtly

I can suggest the "Snowflow" plugin which does a great job of realistic snow distribution.
