*Updated logic to generate a better "glassy" effect.

Transmission Materials in Eevee lack a lot of features that don't work well as they do cycles, like true transmission (for obvious reasons).

This Material for Eevee realtime rendering (although not exclusive),  makes use of a good deal of tinkering, faking and shading mixing to get a realistic looking ready to go glass material with a good set of features:

• IOR.
• Chromatic Aberration.
• Surface Roughness.
• Transmission Roughness.
• Emission.

Includes two presets, Glass and Jelly.

Don't forget to turn on Refraction in render settings

Also check the product docs for advice on setting up your scene for this material.

Just add the blender file to your asset library path, or directly append the material into your project.
