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.

Setting up the lighting


We will start by setting up the lighting of the scene. This will be created by the light sources that belong to the environment itself and are scattered around the scene, plus some other light sources placed where we need them. However, the main light will be coming from the scenic lights.

Getting ready

Let's get started! Open the Chapter06_empty.blend file and select the Walls mesh. In the Shader list you will find several slots already assigned to various parts of the mesh. We will now create the materials for the slot numbers 2 and 4.

How to do it...

We will start by setting up the lights that belong to the scenery itself.

Setting up scenography lights

Follow the given steps for setting up the scenography lights:

  1. Let's add a new material in the second slot and name it EmitterColumn.

  2. Delete default Diffuse BSDF and add an Emitter BSDF node in its place. Leave both Color and the Strength to their default values.

  3. Add a new material in the third material slot and name it EmitterWall...
