Comic color shaders using cycles material nodes

Hi everyone! This tutorial will show you how to create two light responsive comic style materials in Cycles by learning about the Toon BDSF shader’s functions. Creating materials from scratch can be daunting, but by seeing how shaders can be mixed, controlled and modified, I hope to demystify the process for those you who’ve been afraid to dive in and create your own.
