Snow shader

today i came across this tutorial, it doesnt really work for what im aiming for but i believe that with a little bit of playing around i can achieve a better effects, an ice effect!







i will experiment with this method and upload my results up on here! my understanding is that there will be a sparking effect when the camera is animated, the same effect that you find when you look at snow on a sunny day. you never see the same reflective ice crystals twice.
