Manual

• Grayscale sky lighting (Lightmass)
• Set Spec and Roughness values = 1 if use SRO (Specular, Roughness, Other) (Sample in MI folder)
• Fresnel controls for metals face=1. 90 = 1 - (sample in MI folder)
• Experiment with mixing base layer and coat layer. 
• Cube map is situated in F_Cube material function, just replace with one you need. Try to use same values ( brightness-contrast-saturation) for cube and env texture.  ( for instance Sky texture brightness 2.0, cube texture brightness 2.0) 

For instance blurry base layer and light , less blurry  coat layer for plastics.

Semi reflective and gloss main layer (0.5. 0.5), and coating with max blur on grazing angles ( face 0, 90 1+) for Velvet like effects, etc.

It still in progress, I will tweak and probably fix something. Hopefully will improve lighting model. 

Enjoy
