This is an outline highlight effect system for the Unity 2018.3 SRP HDRP and Unity 2019.2 SRP HDRP (ONLY!).

Besides other existing systems, this effect is NOT only created by using a simple fresnel shader.
It allows to draw highlight outlines to all kind of shapes from simple spheres or cubes to complex meshes.

The system is able to highlight objects when the object is in the center of the viewport and below a specified distance.

But it´s also able to trigger the highlight effect manually or by other scripts.

Both functions can be used at once for several objects.

A detailled manual (PDF) is included that explains the setup step by step.
