Overview of this book

Cycles is Blender's new, powerful rendering engine. Using practical examples, this book will show you how to create a vast array of realistic and stunning materials and texture effects using the Cycles rendering engine. Blender 2.6 Cycles: Materials and Textures Cookbook is a practical journey into the new and exciting Cycles rendering engine for Blender. In this book you will learn how to create a vast array of materials and textures in Cycles, including glass, ice, snow, rock, metal and water. If you want to take your 3D models to the next level, but don't know how, then this cookbook is for you! In this practical cookbook, you will learn how to create stunning materials and textures to really bring your 3D models to life! Diving deep into Cycles you will learn Cycle's node-based material system, how to set-up a 3D scene for rendering, how to create a natural and man-made materials as well as the correct organization and re-use of Cycles materials to save you time and effort. To ensure that your creations look stunning you will learn how illumination works in Cycles, improve the quality of the final render and to avoid the presence of noise and fireflies. Each chapter of Blender 2.6 Cycles: Materials and Textures Cookbook builds on the complexity of the last so that by the end of this book you will know how to create an impressive library of realistic-looking materials and textures.

Preface

Creating tree shaders – the bark


There are several different ways to build trees in a 3D package: starting from the simpler low poly objects such as the billboards used in video games (simple planes mapped with tree images on a transparent background) to slightly complex objects where a trunk mesh is attached to a foliage mass made of little alpha textured planes, each one representing a leaf or even a twig, to more complex and heavy meshes where every little branch and leaf is actually modeled.

For this two-parts tree shader recipe, we will use a model coming from the many environment assets of the CG short film Big Buck Bunny, the second Open Movie produced by the Blender Foundation. All the movie assets are free to be downloaded, distributed, and reused, even for commercial projects, because they are licensed under the Creative Commons Attribution 3.0 (http://creativecommons.org/licenses/by/3.0/).

The general shape of the tree and of the leaves as well is pretty "toyish". This is because...
