Hey guys and girls,
I am really confused with Fresnel setup and there are so many versions online that I do not understand which one should I use and which one is applicable to which situation.
A: I have seen users use actual Fresnel node as factor and mixing two shaders glossy and diffuse and then use IOR index. something like this
B: I also seen some use a Layer weight in combination with curves
C: Some use fresnel with Layer Weight
I am really confused on what is the right way and why you should use one or another? CAn somebody explain me what to do?
Thanks in advance
Serg.
