I’ve shown you a few shading styles in Maya just now, but the point of this project is to bring that into Unity.
Thomas van den Berg was so kind to share his own toon-shader with me, and implant the facing-ratio element from the X-ray shader from metervara. After fiddling with it he’s got my shader working.
With some tuning of my own I’ve added property functionalities to it and I’ve now got a fully functional, adjustable toon-shader with facing-ratio-contour in Unity. huzza!
