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 environment


We will now create the materials for the environment. Even if the materials are not too complex, we will be able to learn some new interesting techniques.

Getting started

We have to go through several materials. We want to achieve a nice sci-fi look, and we will do this with the help of different textures. Let's start with the floor material.

How to do it...

Let's select the floor mesh and add a new material to it, naming it Floor.

Creating the floor

The following are the steps for creating the floor:

  1. Add a Glossy BSDF node and mix it with the default Diffuse BSDF using a Mix Shader node.

  2. Set the Diffuse node's color to RGB 0.005, 0.010, 0.020 and the Roughness value to 1.000.

  3. Set the Glossy node's Color to RGB 0.34, 0.34, 0.34 and the Roughness value to 0.020.

  4. Add an Image Texture node and a Texture Coordinate node. Load the FloorDisp.exr file and use the UV coordinates.

  5. Add a Mapping node by navigating to Add | Vector, and place it between the Texture Coordinate and Image...
