So in Maya 2018 the Toon Shader has been removed entirely as well as mental ray, so in order to achieve a Toony effect there are certain traits that can be tinker with in order to create this simulation. Now of course this isnt going be exactly like hitting a matwerial and hitting apply but rather some traits need to be added to a material in the hypershade in oder to modify the materials properties. For this I'm using an ai'StandardSurface, but this can be applied to multiple materials. Keep in mind every time you want this shader you will need to repeat this process and tweak it to your liking, but you can duplicate this set-up and change the colours rather then having to set this shader up over and over again. So in order to make this toon shader you need 3 things, your base material, so in this case "Red", an Ai'FacingRatio, an AI'Color'Correct and a Ramp Shader. The basic things that need to be tak...
