The settings for the snow material are something like:
diffuse: 244,244,244
reflect: 180,180,180 Fresnel:Y Fresnel IOR: 2.0
reflect glossiness: speckle map, size 25 (I work in mm) dark color rgb54, light color rgb255
refract: rgb75 IOR 1.6 glossiness 0.2 fog color: 89,225,250 fog multiplier: 0.2 fog bias: -0.75
translucency: hybrid back side color: white thickness: 1000 fwd/bck coeff: 0.5 light multiplier: 5.0
bump: 30, speckle map size: 25 black/white
I read somewhere once that its important not to have full 255 for any of the rgb values in the fog color, otherwise the SSS effect won't work.
If anyone has any tips or improvements feel free to add them. I use max 2009 and can share a .mat if its easier. (personally I prefer to recreate materials myself step at a time)
