Download Simple Retro Shader FREE Unity. 

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 a 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. )
