This is a simple Shader asset for creating Retrowave style objects in Unity. You can apply this shader to anything you want. Yes, you can apply it even to Terrains!
It comes with a demo scene that includes a retro car and palm models.
In normal state, they are not looking as glamorous as you expect, so don’t forget to support it with a Bloom effect. It's included in the package. ( No, not Unity's Bloom. )
Note: This won't work on most of the mobile devices because of the requirements of Geometry Shader. Furthermore, Geometry shaders are supported from OpenGL 3.1. If your target hardware/GPU implements below 3.1, then it won't work.
