Iceberg shader in Lighting & Rendering Posted October 19, 2014 Just my artistic 2 cents. But it looks like to me that you have the glacier its self down well and good. Though, it looks like naked ice. I would think that you might want a thin layer of bright and opaque snow, maybe normal in Y based? I'm reminded of the snow shader in Maya which had a Y falloff. I'm specifically looking at the 2nd reference image . You're absolutely right! I started out with a snow shader, but it looked horrible,so I tried the ice first. It's time to give the snow shader another try!
