17 INTRODUCTION Welcome! This book is designed to teach you how to create models and environments in 3D, using two pieces of software: Blender, for 3D design and animation, and GIMP, for 2D image editing. In each chapter I take you through a part of the process of creating three complete 3D scenes. You ll learn how to block out and create models, sculpt and detail them, texture and create materials, use lighting, and render finished images. In the course of the book, I discuss the wide array of tools that Blender and GIMP offer and how to use them in real projects. My goal is to teach you how to approach and finish your own projects in Blender, using three of my own projects to provide the narrative and examples of the tasks required. By the end of this book, you should be able to create your own projects from scratch using the principles demonstrated in the three example projects. Topics Covered Here s a brief summary of each chapter in the book. Chapters 1 and 2 offer an introduction to Blender and GIMP. You learn what they are, where you can get them, and what you can do with them. I also introduce you to their user interfaces and the basics of working with them. Chapter 1 focuses on Blender. We look at adding and manipulating objects, saving and loading, and best practices when working on a project. In Chapter 2 we examine creating images in GIMP using its various brushes and filters, as well as how to work with layers and selections. Chapter 3 covers gathering reference material, creating concept art and using these materials in Blender to make it easier to bring your ideas to life in 3D. I discuss using orthographic references, creating reference sheets, and importing reference images into Blender s 3D Viewport to use while modeling.

18 In Chapters 4 and 5 we move on to blocking in the most important aspects of a scene with simple geometry and then fleshing out these basic forms with more detailed models. We look in-depth at Blender s 3D modeling tools and how to create models with simple, efficient geometry. Chapter 6 covers Blender s sculpting tools and how to combine them with Blender s Multiresolution modifier to produce a model that can be sculpted like clay perfect for creating detailed, organic models. Chapter 7 looks at how to modify the highresolution, sculpted geometry from Chapter 6 to create simpler geometry. We look at a few of the different methods Blender offers for retopology and how they can be applied to turn our sculpted meshes into final models. Chapter 8 looks at Blender s UV unwrapping tools that allow you to map 2D images onto the surface of your models. This lets you paint on them and give them colors and textures. Chapter 9 covers creating strand particle systems with Blender s particle tools. These can be used to generate hair and fur, and Blender s particle mode brushes allow you to comb and cut that hair or fur into many shapes and styles. We look at the various settings for particle systems and how to use Blender s child particles to generate vast numbers of particles from relatively few parents in order to create complex, thick hair and fur with minimum input. Chapter 10 looks at texture baking, the process of automatically generating textures based on the geometry of a mesh, while Chapter 11 covers texture painting, which combines the baked textures from Chapter 10 with hand-painted details and photographs using Blender s texture painting tools and GIMP. Chapters 12 and 13 cover Blender s materials and lighting options. We look at the Blender Internal renderer and the Cycles render engine, and how each impacts the way we set up our lights and materials. In Chapter 12 we learn how to use the textures created in Chapters 10 and 11 to create materials that give realistic results when rendered. Chapter 13 covers creating lights and how to set them up for both the Blender Internal and Cycles engines to get attractive lighting and shadows that render quickly. In Chapter 14 we bring together all of the components created in previous chapters, including models, lights, materials, and textures, to render our final images. We discuss the most important render settings for the Blender Internal and Cycles engines, along with how to get the best results quickly. We also examine Blender s node-based compositor and how to use it to further post-process your final renders. Finally, we use GIMP for some extra touch-ups and for painting backgrounds for our images. In Chapter 15 we take a final look at the projects covered, and think about what could be done to take things further. I cover adding a few embellishments to the projects and look at them from some different perspectives, before examining ways to take our still images and make them move with Blender s rigging and animation tools. What Isn t Covered Blender is an extremely powerful 3D design and animation package. It has tools for modeling, texturing, creating materials, and particle systems, as well as tools for rigging and animation, compositing, and scripting; a full-featured game engine; a nonlinear video editor; and some advanced fluid, cloth, and rigid body-simulation tools. This book attempts to deal only with the aspects of Blender that are needed to create, texture, and render models as still images. It doesn t cover Blender s rigging and animation tools, simulation tools, or the game engine. There are a wealth of other resources out there on such topics. If you re interested in finding them, try Requirements To make the most of this book, you will need a reasonably current computer, running a recent version of Microsoft Windows, Mac OS X, or Linux. In particular, when it comes to the sculpting portions of the book, some extra RAM (8GB is good) and a reasonably fast graphics card will prove useful. A pressure sensitive pen tablet (for example a Wacom Bamboo or Intuos) will be really helpful when you reach the texturing and sculpting sections of the book, but it isn t an absolute necessity. The Projects In order to provide a common thread as we progress through this book, I ve chosen to center the discussion on three projects. Each was chosen to provide different challenges and thus provide you with broad, practical knowledge of the tools and options in Blender and GIMP. xvi Introduction

19 The Bat Creature The Bat Creature project focuses on organic modeling to create a humanoid, if monstrous, creature (Figure 1). For this project we first create a simple base mesh and then sculpt the more complex, organic forms of the body with Blender s sculpt tools. We complement this by creating fur with Blender s particle systems. We move on to unwrapping and texturing our creature and then create realistic materials for the skin and fur, which feature subsurface scattering and realistic hair. We render this project with the Blender Internal engine in order to use its highly customizable materials and fast, efficient rendering of hair and fur. Finally we create some dramatic lighting in Chapter 13, where you learn how to get the best results from Blender s lights and how to achieve realistic shadows when working with fur. The Spider Bot In contrast to the organic forms of the Bat Creature project, the Spider Bot project will show you how to create a mechanical-looking, hard-surface model of a robotic spider (Figure 2). This task requires a different approach at each stage of the project when compared with the Bat Creature. We begin by blocking in basic forms with simple geometry, but we use duplication to create the repeated parts of the model, such as the legs. When sculpting we use Blender s hard-surface brushes to arrive at a smoother, less organic final result. Then we use Blender s retopology tools to refine the model into something smooth and sleek. Finally, we render this project with the Cycles render engine because it offers realistic rendering of shiny materials and complex lighting. The Jungle Temple The Jungle Temple project centers on an environment instead of a character: a ruined temple deep in the jungle (Figure 3). We look at blocking in a scene and keeping its composition tailored to the camera. We use duplication, particle systems, and Blender add-ons to create varied vegetation. When texturing, Figure 1: The Bat Creature Figure 2: The Spider Bot Introduction xvii

20 we focus on creating multiple seamless textures using GIMP, which can be tiled and repeated across multiple objects to allow a wide variety of materials to be created using only a few unique textures. We render this scene with the Cycles engine (which allows for the quick creation of realistic lighting) in Chapter 14, and then use Blender s compositor to add some post-processing. Finally, we use GIMP to paint a background for the scene. feature supplementary information and tips that offer more general guidance that you should find useful in a wide range of projects. Resources Accompanying This Book The DVD accompanying this book contains all the files for the projects in this book, including separate.blend files for each project (corresponding to each chapter in the book) and each project in its final state at the end of each chapter (where relevant). These resources should allow you to look in-depth at the workings of each project and to examine how each one takes shape. Creating 3D art is a complex process, and the end product is often a result of some amount of experimentation. These project files are not a literal snapshot of the projects as they progressed; instead, they are an idealized, tidiedup version of what each project would look like at a given stage. Also included are the textures used for each project,.blend files with some useful brushes for sculpting and MatCap materials (see Chapter 6 for more on sculpting and MatCap materials), and the GIMP brush created in Chapter 11 that you can use in your own projects. You can use these files any way that you like.

These may not be distributed unmodified without permission from CGTextures. Figure 3: The Jungle Temple How to Follow the Projects While the projects form the main narrative of this book, I don t cover every step of creating them. Instead, I focus on the most important or difficult aspects of creating each project at each stage of its development and leave the rest as an exercise for you should you wish to produce a similar result. I hope that this approach will show you how to go about creating all kinds of 3D images with Blender and the thought processes and challenges involved. To help with this goal, most of the chapters in this book also Let s Begin This introduction has hopefully let you know what this book is about and where in the book you can look for the information you need. I ve outlined the projects we will be working through and what you can hopefully expect to learn from them. Now we can start getting acquainted with Blender and GIMP, before diving into the projects. If you re already comfortable with the basics of Blender and GIMP, you can skip to Chapter 3. Otherwise, the next two chapters should provide a basic introduction to the workings of the software we will be using in this book. xviii Introduction

21 1 INTRODUCTION TO BLENDER In this chapter, we will look at the basics of using Blender in order to build a foundation for our work in later chapters. We ll explore its user interface, how to navigate the 3D Viewport, and how to add and interact with objects. Throughout this chapter, I ll point to later parts of the book, where various topics will be covered in greater detail. If you are already comfortable with Blender, feel free to skip to Chapter 2, on GIMP, or Chapter 3, on preparing your projects. About Blender Blender is a free open source 3D design and animation package, available for Windows, Linux, and Mac OS X. Originally created as an inhouse animation package for Dutch animation studio NeoGeo, it was later released under the GNU General Public License when its developer, NotANumber, went bankrupt and the Blender community raised 100,000 to pay creditors to release the Blender source code. Since then, Blender has undergone continued development by the Blender community, overseen by the Blender Foundation (headed by Ton Roosendaal, one of the original developers of Blender). The current version (Blender 2.6x, as this book goes to press) boasts a wide array of features competitive with many commercial 3D applications and has a committed and enthusiastic community creating art and animation with it. Blender is used today by many animation studios, game developers, artists, and hobbyists. It has been used to make feature films, short films, and games. Of particular note are the Blender Foundation s open movie projects communityfunded short film projects that are used to drive the development of Blender forward by using it in a production environment. To date, four short films and one game have been completed, each yielding significant improvements and new features in Blender s repertoire. The first short film, Elephants Dream, premiered in It s a surreal tale in which two characters travel through a bizarre mechanical

22 world. It introduced particle-based hair and fur rendering, as well as new animation tools and improvements to Blender s render engine. In 2008, Big Buck Bunny introduced improvements to fur rendering, particles, and the render pipeline, as well as more advanced rigging and animation constraints. In 2010, Sintel, a tale about a girl and her dragon, brought advanced sculpting tools, new simulation tools, and shading and rendering improvements. The latest open movie, Tears of Steel, focused on adding advanced visual effects tools to Blender. It brought major improvements to the new Cycles render engine and has introduced camera tracking tools, new features for Blender s compositor, improved simulation tools, and better color management. Current, stable Blender builds for Windows, Linux, and Mac OS X are available from In addition, you can find development builds featuring the latest updates from These development builds are designed for more advanced users or those who wish to try new features; they can be unstable, so stick with the official builds for important work. The Blender User Interface Blender s user interface (UI) has earned a reputation for being difficult to grasp. In earlier versions, this reputation was somewhat justified, but since Blender 2.5, the interface has seen major updates and is now much more predictable and easier to learn. Plus, with the addition of the search function, if you have trouble finding a particular operator, you can search for it by pressing the spacebar to bring up a search dialog in which you can search for operators by name. Once you have grasped the UI, you ll find that Blender is very fast and extremely customizable. Most functions have keyboard commands for quicker access, and the interface is non-blocking, which means that windows and dialogs won t be layered on top of one another, obscuring your view. Layout and UI Terminology When you first start Blender, the default layout should look something like Figure 1-1. The Blender window is broken into areas called editors. These editors include the 3D Viewport, the Properties editor, the Outliner, the Info editor, and the Timeline, as shown in Figure 1-1. Key: Editor Region Tool Shelf Info header Outliner Properties editor header Properties editor Timeline 3D Viewport header Figure 1-1: Blender s default UI layout. The window is broken down into different editors (orange), which are then further split into regions (green). 2 Chapter 1

23 Editors are further broken down into regions. In the case of the 3D Viewport in Figure 1-1, the regions are the Main region (that is, the 3D view), the Header region at the bottom of the editor, and the Tool Shelf on the left. Regions that contain buttons and properties like the Properties editor or the Tool Shelf in the 3D Viewport are further broken down into panels. A panel may contain any number and combination of operator buttons, information, and properties. The panel s name is shown at the top of the panel (see Figure 1-2) and indicates what sort of properties and information the panel contains. Tabs Collapsed panels Click to collapse/expand panel Panel title Drag to reorder panel Figure 1-2: Panels within the Properties editor Switching Editors and Customizing the UI Blender s UI layout is highly configurable. You can switch any editor in the current layout to a different editor type by selecting a new one from the drop-down menu at the far left of the Header region (see Figure 1-3). You can also resize existing editors and add or remove editors by splitting or merging existing ones. To resize an editor (or a region), click and drag on its border. To split or merge editors, rightclick the editor s border and choose either Split Area or Merge Area. (In later chapters, we ll use this technique to adjust Blender s layout to better suit various stages of each project.) Multiple Layouts Figure 1-3: Blender s different editor types Because different UI layouts are suitable for different tasks, Blender allows you to store multiple UI layouts so that you can switch between them as you work. To switch layouts, click the screen layout drop-down menu in the Info editor header (see Figure 1-4). By default, Blender includes layouts named Animation, Compositing, Default, Game Logic, Scripting, UV Editing, 3D View Full, Motion Tracking, and Video Editing, each of which is pretty well suited to the task that it s named for. (Default is the default layout when you start Blender and is good for modeling.) To add your own layout, click the + icon at the right of the drop-down menu to copy the current layout and modify it, or delete the current layout by clicking the X icon. Layouts are saved along with your.blend file when you save your work, so you can return to them when you reopen the file. Introduction to Blender 3

24 you want using the methods outlined above. Use CTRL-U to save the current file as the new default start-up file. (To restore the original default.blend file, select Load Factory Settings from the File menu and then save the default.blend file again.) Editor Types Each of Blender s editors offers a different functionality. Not all editors will be useful to us in the course of this book, so I will discuss just those that are relevant to the projects we ll tackle. Figure 1-4: Switching layouts with the screen layout drop-down menu You can make a layout available by default by saving it as part of the default.blend file, the file that is loaded upon starting Blender. To do so, load the default.blend file (CTRL-N) and then create the layout The 3D Viewport This is Blender s most important editor type. The 3D Viewport (see Figure 1-5) is where you can view your scene and its objects and then move, manipulate, and organize them. The 3D Viewport has four regions: the main 3D view; the Header, which is found either at the top or bottom of the editor (usually the bottom); the Tool Shelf (T) Lamp Properties (N) Camera Active object (highlighted) Manipulator widget 3D cursor Display mode Mode Manipulator widget options Layers Header Figure 1-5: Blender s 3D Viewport in detail 4 Chapter 1
