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 wood material for the table and the fence


The last material we will be dealing with in our scene is the wood of the table and the fence.

Getting ready

We saw how to create a parquet material in Chapter 3, Creating an Interior Scene, but this kind of wood is different. It is worn, and hence much less reflective. Let's see how we can deal with it. Let's move the sunlight back to the first layer and select the table mesh. Add a new material to it and name it WoodPlanks.

How to do it…

Let's see how to create the wood for the picnic table:

Creating the wooden planks

  1. Add Glossy BSDF and a Shader Mix node. Mix Glossy BSDF with the default Diffuse BSDF and set the Glossy influence to 15%.

  2. Change Roughness of Diffuse BSDF to 1 and Glossy BSDF distribution model to GGX.

  3. Add an Image Texture node and a Texture Coordinate node. Use UV coordinates and load the WoodPlanks.jpg texture.

  4. Connect Image Texture to the Color input sockets of Diffuse BSDF and Glossy BSDF.

  5. Add RGB to BW and an RGB Curves node...
