Hey guys, i've been tryin to achieve a good looking snow material since a while. Not the easiest thing in the world!
I've gathered as many references and other render engine user renders to see how they approached it.
So far looks like most people go without a subsurface approach, because it is very expensive in render times. I've tried both ways, and personally while the non-sss method is fine for far landscape, exteriors and ideally objects that are far from camera, when you have something you want to give a bit of detail, you have to go with sss.
Anyway i wanted to gather some tips if you have any, here is what i have done so far, its still in progress
Most problem i am facing is to give to the shader enough glittering effect, that microfacet reflection that happens when its being hit by the sunlight
Anyone did manage to achieve a snow shader in maxwell? I've seen some impressive vray shaders but im no vray user and also i like challenges!
This shader is made of 4 layers, SSS base, diffuse, a reflective layer set on glossy, and the sparkling glittering level, which at the moment is giving me some trouble. The sss gives a nice touch to it, if you check the rabbit ears, still have to improve
comments are welcome
