Description

A simple additive shader that uses a ramp texture to give it that X-Ray look.

Usage

Create a ramp texture for the facing ratio lookup. For a standard X-Ray look make it light to the left and dark to the right. This texture will be mapped onto the object depending on the angle between the surface normal and the view direction.
