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.

Compositing the scene


Our scene is almost ready, but we will give it a final touch in compositing to make it really stand out.

Getting ready

Let's change the mode of the node editor to Compositing and check the Use Nodes option in the lower part of the screen.

How to do it…

  1. Add a Glare node (Add | Filters) and connect the Image output from the Render Layer node to it. Leave the mode to Streaks and set the quality to High. Change the Iterations to 5.000 and the Color Modulation to 0.500. Also change the Mix value to 1.000 and the Threshold value to 3.100. Finally, set the Streaks value to 2.000 and the Fade value to 0.970.

  2. Duplicate the Glare node and change the mode to Fog Glow. Change the Threshold value to 1.000 and the Size to 9.000.

  3. Mix the two filters using a color Mix node in the Add mode with a Fac value of 1.000.

  4. Add a Color Balance node and connect the Image output of the Render Layer node to it. Set the following values for Lift, Gamma, and Gain respectively: HSV 0, 0, 0.98, HSV 0.55...
