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 materials for the plant in the scene


In this recipe, we will have our first brief contact with organic materials, which is a really challenging topic in computer graphics. We will go more in depth on this in the last chapters of the book, but this will be a good introduction.

Getting ready

It is time to create the material for the plant in our scene. To start, let's select the object named Plant and add a material to it. Name the material Leaf01 and go to the materials' node editor.

How to do it…

To create the plant materials, follow these steps:

  1. Add a Glossy BSDF and Mix Shader node. Set the Glossy roughness to 0.080 and change the algorithm from Beckmann to GGX.

  2. Mix the default Diffuse BSDF and the Glossy BSDF with the Mix Shader node. Put the Diffuse on top and the Glossy at the bottom, and use a Fac value of 0.200. Also set the Diffuse roughness to 1.000.

  3. Now, let's add a Translucent BSDF and an Add shader node. Add the output of the previously added shaders and the Translucent node...
