Snow doesn't gradually apply, but rather switches on and off
I was following the tutorial and got to the point at 11:10 in the video, where you apply the material to the rocks. What happens in my project is that the shader either applies the snow to the entire rocks' surfaces, or not at all - it doesn't respect the dot product like it does in the video. I also tried out the "ShaderSchool_Examples_Snow_Basic" material, and the same thing happens.
I'm suspecting something wrong with the dot product calculation, but I'm not sure why it works on your version, while it doesn't work on my version, when they're both the same.
Does anybody see the problem? Again, I'm using the example shader provided from the downloads.
