Blender Cycles: Lighting and Rendering Cookbook - Second Edition

Overview of this book

Blender provides a broad spectrum of modeling, texturing, lighting, animation and video post-processing functionality in one package. It provides cross-platform interoperability, extensibility and a tightly integrated workflow. Blender is one of the most popular Open Source 3D graphics applications in the world. Modern GPUs (Graphics Processing Unit) have some limitations for rendering complex scenes. This is mainly because of limited memory, and interactivity issues when the same graphics card is also used for displaying and rendering frames. This is where Cycles rendering engine comes into play. Cycles is bundled as an add-on with Blender. Some of the features of Cycles is its quality, speed and having integrated industry standard libraries. This book will show you how to carry out your first steps in Cycles - a brand new rendering engine for Blender. In a gradual and logical way, you will learn how to create complex shaders and lighting setups to face any kind of situation that you may find in Computer Graphics. This book provides information on how to setup your first application in Cycles. You will start by adding lights, materials, and textures to your scene. When it's time for the final render, you will see how to setup Cycles in the best way. You will learn about a wide variety of materials, lighting, techniques, tips, and tricks to get the best out of Cycles. Further on in the book, you will get to know about animation and still shots, and learn how to create advanced materials for realistic rendering, as well cartoon style shaders. This cookbook contains a wide range of different scenes, proposed in a structured and progressive order. During this journey, you will get involved in the concepts behind every step you take in order to really master what you learn.

Creating the ice and snow materials


In this recipe we are going to create all the material for an iceberg. Our target is to have snow on the flat surfaces and ice on the slopes, where it is too steep for the snow to stay. Let's get started!

Getting ready

We will create the ice and the snow using a single material, and mix them using a new technique. Select the iceberg mesh and add a new material to it.

How to do it…

We will now see the steps required to create the ice as well as the snow material.

Creating ice

The following are the steps to create ice:

  1. Add Glossy BSDF and Glass BSDF and mix them using a Mix Shader node. Let's put Glossy in the first socket and Glass in the second one.

  2. As input for the color of both the BSDFs, we will use a color Mix node with Color1 as white and Color2 as RGB 0.600, 1.00, 0.760.

  3. As input for the Fac value of the color Mix node, we will use a Voronoi Texture node with the Generated coordinates, Intensity mode, and Scale 100. Invert the color output using an Invert...
