In Chapter 3, Creating Natural Materials in Cycles, we have seen some of the simpler natural materials that are possible to build in Cycles, while keeping them out of any landscape context to make them more easily understandable.

Now, it's time to deal with more elaborate natural materials. In this chapter, we will particularly examine the way to mix different basic shaders to mimic the look of complex natural objects and their environments (very often the two things fit together neatly).
