A few months back there was a challenge to create a snow shader ..I was so busy that I couldn't participant but the idea was in my mind till today where i give it a try : ))
It's my first time using CoronaSkinMtl and I still need to dive more into it but for now i think it did the job nicely : ))
The snowball shader is fully procedural so no UV is required, but for the ground I added a bitmap to the mix to get extra details there .
WIP to show the progress of the material . (only the first one is Arnold )
