Unreal Engine

■ Unreal Engine a game engine developed by Epic Games first illustrated in the 1998 first-person shooter game Unreal The latest release is the Unreal Engine 3(UE3), designed for

• Microsoft's DirectX 9 (for Windows and Xbox 360)• DirectX 10 (for Windows Vista) • DirectX 11 (for Windows 7 and later)• OpenGL for Mac OS X, • PlayStation 3, Wii U, iOS, Android• Stage 3D for Adobe Flash Player 11.

Unreal Engine

■ Versions Unreal Engine 1 (1998)

• First generation Unreal Engine integrated rendering, collision detection, AI, visibility, networking and file system management into one complete engine.

Unreal Engine 2 (2002)• Support for the GameCube and the Xbox. (PlayStation 2 in UE1)• UE2.5 : improved rendering performance and added vehicles physics

running on the Nintendo 3DS Unreal Engine 3 (2004)

• designed for DirectX, OpenGL, including iOS, Android, and Adobe Flash Player • November 2009, Epic released a free version of their engine, called the Unreal

Development Kit (UDK) Unreal Engine 4

• targets the next generation of PC HW & consoles after the seventh generation. • Unreal Engine 4 would be unveiled to limited attendees at the 2012

Game Developers Conference.

UE3 vs UDK vs UT3

■ UE3 vs UDK vs UT3 UE3 is Unreal Engine 3. UDK(Unreal Development Kit) and UT3(Unreal Tournament 3)

are both powered by Unreal Engine 3 Unreal Engine 3 = UDK and UT3. Unreal Editor interface between the UDK and Unreal

Tournament 3 are essentially very similar.

UE3 vs UDK vs UT3

■ UDK Free stand alone version of Unreal Engine 3. www.udk.com New engine updates, and improvements being released almost on

monthly basis. Purchase a license and sell your game with UDK. Ideal to create stand alone games. You can package your created maps and games as a stand-alone

executable. Free to create any game, only limited by know how. Limited amount of models and textures UDK was designed in mind for game designers and environment

artists to take the base of UDK and create brand new custom content

UDK does not include Unreal Engine 3 C++ source code access

UE3 vs UDK vs UT3

■ UT3 Purchase the game and editor comes with it. Lots of models, textures, particles, vehicles, weapons. Large community. You'll have access to all the source code files for weapons,

vehicles and characters in Unreal Tournament 3. Complete full game. Ideal for level design. If you are not good with creating

custom models and textures using 3d modeling package, Unreal Tournament 3 is good choice.

Has not been updated with new features like UDK and runs on the old build of Unreal Engine 3.

UDK Installation

■ UDK DOWNLOAD AND INSTALLATION Download latest version of UDK here. The default directory for installing UDK is C:\UDK\UDK-

VersionRelease Version Release will be the month and year of the UDK built that you

downloaded.

■ UDK FOLDER STRUCTURE Binaries: game/binary executables Development: source code for UDK Engine: engine files UTGame: game files

• for level design and environment creation the important folder here is content folder. (UTGame Content)

• The packaged environments assets such as models, textures, materials, sounds and such are stored here.
