Enhanced Fresnel

Description

This node group takes roughness into account when calculating Fresnel.

The group also has enhancements for roughness and color.

**Grazing Reflectivity:**
This produces realistic reflections at grazing angles.
The *Grazing Reflectivity* parameter controls the strength.
The *GR Falloff* parameter extends the reflections.

**Color Correction:**
This addresses an issue that causes color to appear too dark at grazing angles.

The group is compatible with 2.79 and 2.8.

I have also created a Grazing Reflectivity group for the Principled shader. https://www.blendswap.com/blend/23960

You're welcome.

Just to clarify, does a higher falloff extend or shorten the reflections?

Higher values extend the reflections.
