Multiple Procedural Toon Shaders that are optimized for maximum in game performance.
There are effects like outlining, rim lighting, specular highlights, etc.
You can use procedural ramps on every visual aspect: shadows, rim lighting, specular reflections.
1) Effects you don't want to use on your material won't be processed(in-game optimization)
2) You can use ramps(or not) on each effect
3) Future updates will add more features!
