Introduction toAdvanced LevelDesign

Welcome to advanced level design in Unreal Engine 3! Whether

you’ve read our previous two volumes, created your own games and

levels, or just played games built with Unreal Engine 3, you proba-

bly realize just how powerful this game engine can be. You’ve seen

Unreal Engine 3 create vast worlds with lush environments that

stagger the senses of your players. You already have some idea of the

power the Unreal Editor gives to game artists.

Now, it’s time to kick things up a notch. Heck, more than a notch: It’s

time to take Unreal Engine 3 to the limits, and make your gaming

experiences even more stunningly believable.

If you want to shake your players to the very core, you’re gonna have

to master the heavy-duty stuff: particle systems, custom animations,

physically reactive dynamic objects, advanced materials, and more.

All that stuff ’s built into Unreal Engine 3—and we’re going to show

you how to use it. Not just a little: to the fullest.

Chapter 1

Who Is This Book For?A little housekeeping first. (Just a little.) As you’ve probably figured out by now, this isn’t intended

as a beginner’s book.

Now, if you’re a beginner or have only limited experience, let’s be clear: We are not blowing you

off. Quick learners should be able to follow along: just go slow, and take it a bit at a time. The

tutorials are written in an easy-to-follow, step-by-step manner that should allow users of just

about any experience level to participate—and we know, because we’ve been training Unreal

developers for years.

But if you’re already comfortable with the Unreal Editor, and you’ve done basic Unreal program-

ming, you’ll definitely be able to move faster.

What Should You Know Before You Start?This book is intended to be used with the game Unreal Tournament 3.

Many of the basic concepts we teach you apply to other Unreal Engine 3–based games that pro-

vide access to the Unreal Editor. However, many of our tutorials rely on game assets that come

with Unreal Tournament 3. What’s more, other games sometimes change the engine and the

editor, which could make them work differently—or at least confuse the heck out of you. We

wouldn’t want that!

As we’ve already said, we do some handholding throughout the tutorials, but you’ll be better off

if you’re at least basically familiar with the Unreal Editor’s key concepts and controls. Ideally, it’d

be way cool if you’ve already explored:

• Navigating perspective and orthogonal viewports

• Creating additive environments using BSP brushes

• Navigating and creating assets within the Generic browser

• Loading and unloading asset packages within the Generic browser

• Placing objects into levels from the Generic and Actor Classes browsers

• Adjusting actor properties within the Actor Properties window

• Setting up basic Kismet sequences

• Creating basic materials with the Material Editor

• Simple keyframe animation using Matinee

Haven’t done all that? As someone once said, don’t panic. As we keep saying, you’ll still be able to

follow along, just more slowly. But you’ll definitely have a smoother, faster learning experience if

Included Assets and Game Assets 3

you’re already familiar with Unreal Engine 3 and the Unreal Editor. To that end, you might want

to check out the following training resources:

• Mastering Unreal Technology, Volume I: Introduction to Level Design with Unreal

Engine 3—The first volume in this series, this book gets you up-and-running with the

Unreal Editor. It’s specially designed for anyone just getting their feet wet with Unreal

Engine 3 modding.

• Unreal Tournament 3: Collector’s Edition—The Collector’s Edition version of Unreal

Tournament 3 includes a separate DVD that contains many hours of Unreal Editor

training—including several videos geared specifically for beginners.

• www.3dbuzz.com—That’s us! 3D Buzz, our company, delivers hours of professional-

quality video training content covering Unreal Technology, programming, 3D graphics,

and more! Get started right away by watching our Video Training Modules, or dig

through our forums for tons of valuable information. And, since this site’s staffed and run

by this book’s authors, it’s a great way to get in touch with us. (Come, say hello—really!)

What We Mean By “Advanced” Level DesignThe Unreal Editor brings together a vast toolset and immense power. Some of its tools are sim-

ple, straightforward, and haven’t changed much over the years. Others have changed dramatically

in Unreal Engine 3, offering far more power and flexibility than ever before. And some are brand-

new to game editing: They bring elements of high-end film and special effects production into

gaming for the first time.

In this book, we focus primarily on the tools that are either new or dramatically improved in

Unreal Engine 3. But we also show you breakthrough techniques for making the most of com-

monly used tools like the Material Editor, so you can create more powerful assets than 99% of the

people who are using it right now. (Hey, it’s a competitive world. These days, average just won’t

cut it anymore!)

Included Assets and Game AssetsBeyond your sparkling personality, you need plenty of other assets to complete the tutorials in

this book. Textures. Sounds. Images. Stuff like that.

Fortunately, you’ll find many of those assets on the DVD we’ve bound into the back of the book.

There’s a folder for each chapter that requires these assets.

www.3dbuzz.com

The other assets you need are installed with the Unreal Tournament 3 game. You’ll find them

within packages (UPK files). After a default installation, you’ll find those packages in the follow-

ing installation folder:

C:\Program Files\UT3\UTGame\CookedPC

If you’ve installed to a different drive or folder, your path will start out differently, but once you

drill down to the UT3 folder, everything underneath it should follow the same folder structure.

Within the CookedPC folder, you’ll see several subfolders, each containing several packages. The

subfolders you care about most are:

• Environments—Here are the assets used to build the levels that shipped with Unreal

Tournament 3, such as static meshes, textures, and materials. These packages are orga-

nized into themes, which makes it easier to find the assets you need, based on what you’re

trying to create.

• Characters—Need a UT3 character for a cinematic sequence? They’re here, and each type

of character is itself divided into various packages.

• Maps—Need to change an existing

map? Want to see how an effect was

created in one of Unreal Tournament

3’s built-in maps? Those maps are

here.

• Effects—Here are the packages you

need to create particle effects (explo-

sions, fire, and so on), lens flares, vehi-

cle and weapon effects, and other

special effects.

Working with INI FilesA few of our tutorials require you to alter an Unreal Tournament 3 INI file in order to see the

result in-game. When this happens, we tell you exactly which files to alter and how to do it.

These INI files can be found within your local Documents folder. If you’ve performed the default

Unreal Tournament 3 installation on a Windows system, that’ll be here:

Documents\My Games\Unreal Tournament 3\UTGame\Config\

NOTEKeeping things simple for you isn’t the only reason forUnreal’s folder and package structure. There’s anequally important reason: memory usage. When youload a package, its contents are all placed in memory.Since you don’t have infinite memory, you don’t wantto load more packages than necessary. The folder andpackage structure helps you load only what you needright now. (How many packages is too many? Thatdepends on your system’s specs. But if you’re noticinga slowdown or occasional instability, you just mighthave too many packages in memory. Unload a few!)

Future Software Changes 5

Unlike, say, Registry entries, INI file changes are dead simple to remove. Just delete your altered

INI file. Next time you launch Unreal Tournament 3 or the Unreal Editor, it’ll create a new,

replacement INI file using the default settings.

By the way, when you create a full modification for Unreal Tournament 3, players can include INI

files that pertain only to their mod, so other gamers can view their creations.

Future Software ChangesFinally, if we had lawyers, they’d probably tell us to say this: We’ve done our best to make sure this

book’s tutorials and concepts are up to date and accurate at the time we wrote them. They reflect

everything we know about writing accurate, reliable Unreal code. We’ve been darned careful. But

we can’t predict the future. (Find someone who can, and we’ll hire them ASAP!) Bottom line: If

someday, some patch or software update changes the way these tutorials behave, hey, that’s out of

our hands.

With that, let’s say goodbye to the lawyers, and get down to work.
