Have you ever seen a complex Cycles shader that uses some strange math nodes to create cool features you'd like to play with? Ever tried to get your head around it and ended up with a headache? This tutorial shows you how you can create a Cycles shader node-tree from a physical formula. In the end you'll be able to understand other people's setups a lot better and be able to create your own re-usable shaders from physical formulas you can find in textbooks or on the internet.
