Snow A simple snow surface implementation is to calculate dot product of normal and a custom direction. half snowSurfaceMask = clamp(dot(normalWS, _SnowDirection), 0.0f, 1.0f); It is similar to NdotL. We can add some small scale gradient noise or simple noise to this mask, and make it white. When we change the _SnowDirection, we might add some unwanted artifacts. To solve this problem, multiplying another upward snow mask to the snow surface mask....
