Blender 3D By Example - Second Edition

By: Oscar Baechler, Xury Greer

Overview of this book

Blender is a powerful 3D creation package that supports every aspect of the 3D pipeline. With this book, you'll learn about modeling, rigging, animation, rendering, and much more with the help of some interesting projects. This practical guide, based on the Blender 2.83 LTS version, starts by helping you brush up on your basic Blender skills and getting you acquainted with the software toolset. You’ll use basic modeling tools to understand the simplest 3D workflow by customizing a Viking themed scene. You'll get a chance to see the 3D modeling process from start to finish by building a time machine based on provided concept art. You will design your first 2D character while exploring the capabilities of the new Grease Pencil tools. The book then guides you in creating a sleek modern kitchen scene using EEVEE, Blender’s new state-of-the-art rendering engine. As you advance, you'll explore a variety of 3D design techniques, such as sculpting, retopologizing, unwrapping, baking, painting, rigging, and animating to bring a baby dragon to life. By the end of this book, you'll have learned how to work with Blender to create impressive computer graphics, art, design, and architecture, and you'll be able to use robust Blender tools for your design projects and video games.

Simple materials and the nodal workflow

The kitchen has several objects whose materials are simple to set up and will serve as a good introduction to the basics of PBR. Eevee's real-time rendering is based around controlling a limited set of variables that have the potential to replicate all of the physically possible materials in the entire world. Take any dirt, meteor, banana, or liquid in the universe, and you can map its properties from a value of 0 (0%) to a value of 1 (100%):

Black to white colors (distributed over Red, Green, and Blue (RGB) pixels)
Transparent to opaque
Rough to smooth
Dielectric to metallic

Nodes are a way to map those values. A value of 0 Roughness means not rough at all. A value of 1 Roughness means very rough. A value of 0 Transparency is completely opaque. A value of 1 Transparency is completely transparent. If you took a photograph, it has...
