- Keyframe Animation
- Skeletal Animation
- Facial Animation
- Animation Blending
- State-of-the-Art Animation !
The Unreal animation system is a skeletal animation system that gives full control over every detail, every muscle and every bone. Make your world more vibrant and add more personality with detailed animations.
UDK supports up to four bone influences per vertex, allowing for subtle nuances in all your scenes. Full mesh and bone LOD support is also built right into UDK.
The AnimSet Viewer tool will organize your animations and help you browse through your meshes. This gives you the ability to add game-specific notifications at specific points of the animation and allows you to place sockets on bones to be used for attaching objects to the skeleton during gameplay.
Animation is driven by an AnimTree, a tree of animation nodes including:
* Blend controllers, performing an n-way blend between nested animation objects.
* Data-driven controllers, encapsulating motion capture or hand animation data.
* Physics controllers, tying into the rigid body dynamics engine for ragdoll player and NPC animation and physical response to impulses.
* Procedural skeletal controllers, for game features such as having an NPC's head and eyes track a player walking through the level.
* Inverse Kinematics solver for calculating limb pose based on a goal location (e.g. for foot placement).
* Group animations, handling notifications for the whole group. Synchronize all or a subset of them.
* Morph target animation, allowing the control of morph target blend weights from animation data, with support for material control as well. Morph animation can be authored in Maya and morph data can be exported via ActorX. Skeletal animation can now control vertex and material animation, with preview in the AnimSet Viewer.
* Plus, there are no restrictions on the number of animations playing at the same time, number of blends, or post-processing operations.
FaceFX Facial Animation.
UDK ships with FaceFX, the cutting-edge solution that enables developers to create realistic facial animation from audio files.
FaceFX makes it easy to batch process thousands of WAV files for your game, add expressions to a single animation without ruining the lip-synchronization, tweak an animation to perfection, or integrate the entire solution into your art pipeline.
Everyone can experience the power of generating high-quality facial animations with FaceFX directly from UnrealEd.
* Animate normal maps with custom Unreal Engine 3 Face Graph nodes.
* Trigger FaceFX animations from Unreal Matinee.
* Import and export XML files for pipelines using FaceFX 2009 and FaceFX 1.7.x in UE3.
Every aspect of the FaceFX pipeline is customizable, from speech targets to gesture curves. With direct support for the FBX file format and plug-ins in 3D Studio Max, Maya, XSI, and MotionBuilder, FaceFX interfaces seamlessly with the best tools in the business.
- Work with a dynamically deformable base height map extended by multiple layers of smoothly blended materials. Then layer on procedural weathering, such as grass and vegetation or the snow on mountain peaks. UDK's artist-driven terrain system lets you place and customize vegetation, structures and countless points of interest throughout your game world.Terrain in UDK is easy to edit and alter to create compelling levels and worlds.
- Terrain building and editing tool. Uses a dynamically deformable base height map extended by multiple layers of smoothly blended materials including displacement maps, normal maps and arbitrarily complex materials, dynamic LOD-based tessellation and vegetation layers with procedurally-placed meshes. Terrain is considered an actor in UDK, and therefore its shape is easily controlled via a height map in a paintbrush-like manner. Painting and sculpting geography is a simple task handled with the sweep of the mouse.
- Artist-controlled layers of procedural weathering For example, you can place grass and vegetation on the flat areas of terrain, rock on high slopes and snow atop peaks. Grass and other foliage can be added either as a material or as decorations called DecoLayers. Materials allow foliage to be instantly added to entire map sections while DecoLayers offer deeper placement control.
- Advanced controls over lighting and collision.
- Lightmaps, shadowmaps and collision properties can be edited in detail in order to make the terrain look and perform realistically.

- Give AI-controlled characters increased spatial awareness of the world around them and enable them to make smarter movements with UDK’s gameplay framework and artificial intelligence system. Add life to your game world by using UDK's crowd system with flocking technology, which can simulate hundreds of characters within a scene in real time.
UDK ’s artificial intelligence system provides two robust systems for AI navigation. UDK supports the automatic creation and use of navigation meshes, giving AI-controlled characters increased spatial awareness of their environment and the ability to make smarter movement decisions.
The UDK Navigation mesh implementation optimizes the performance and memory usage of AI in many scenarios relative to traditional node-based navigation systems, thanks to a more efficient representation and less reliance on collision-detection for movement. UDK also provides an up-to-date implementation of the robust and well-tested node-based navigation system used in Unreal Engine games over the last 12 years.
Navigation mesh system provides an accurate representation of an AI's traversable space via a connected graph of convex polygons:
* Memory footprint is reduced with the decrease in nodes being stored.
* Less nodes means less time fixing up cross-level pathing information.
* Pathfinding times go down as the density of the graph being searched shrinks.
* Better representation of the world results in better pathing behavior.
* Paths are automatically generated !
Furthermore, you can add crowds of animated characters to a map with UDK's flocking technology, which directs character movements and animations through a network of crowd destinations and Kismet interaction. UDK's crowd system gives you complete control over the movement and interaction of crowd agents with players and other NPCs using a "plug-in" behavior system.

Ridiculous License Fes
I checked out several engines before settling for Ogre. I was very interested in the Unreal SDK and I admit it sounds great if you want to dabble in game development or anything 3D. But if you really intend to make a living from your product, this isn't the engine for you because of the 25% licensing fees. 1/3 of your income goes to UNcle Sam, another 1/3 as license fee for the UDK? Give me a break. If you intend to actually have revenues, look elsewhere.
The reason why we switched from Shiva 3D and Unity 3D to Unreal Technology.
We have spent several months looking for an easy to learn and use Game Engine for a large commercial project.
We found it when we found UDK. The interface is very easy to use and learn. We didn't have to compile anything. We just use Kismet for visual scripting and Matinee for animation and cinematics without touching a single line of code. The support is the best we've ever recieved for any product. We receive quick and professional support through the forums everytime we have a question or problem.
It is an absolute joy to create something in Maya and then be able to see it in our game faster than we have thought possible.
For someone looking to get into game development for the first time, or a seasoned pro looking for a better way, I highly recommed this game engine. The Unreal Development Kit just wants your game to be a success.
Not my Favorite
In general, I like UDK and it has been used (along with the full Unreal Engine) for huge games. However, I do have some problems with the Engine as a whole.
First, UDK does not offer native C++ support. This means you are stuck writing in Unreal Script which seems like a waste to me. This would be fine with me if they offered free plugin's for Visual Studio or other large and proven IDE's. Since this support requires extra money that's another tick against the engine.
The Editor feel outdated to me. Now, let me clarify that I have no experience modding Unreal games and had not touched the editor before picking this up. I do like the option to drop Primitive shapes into a map and that really speeds up asset design/development, but the editor as a whole doesn't match up to other's from comparable engines such as CryEngine, Unity or the Esenthel Engine.
There are also a number of things I really like about Unreal. It is a leader in new technologies and recently announced it's Global Illumination. Things like that are great to see and make me want to love this engine.
Additionally, Unreal offers performance that simply is better than other Engines. This refers mainly to Esenthel and Unity here who both have notable gaps in their optimization.
On the whole UDK is a great tool for developers that have some experience with Unreal technologies. However, their are alternatives that may suit you better if your goal is not FPS related or if you need access to some of the features of C++ that Unreal Script won't offer.
As an additional note: UDK has a pretty hefty license attached. $99 and 25% is significantly more than the 20% (no up front cost) of CryEngine or the $100 of Esenthel. If you are not serious about your intentions this is not for you.
High quality game engine with a professional tool suite !
The unreal game engine technology is based on a first class rendering engine with an integrated suite of other professional tools that are used in the video game industry these days. I also use UDK because of the fast, veteran friendly interface. Once you know it, you'll see that it's designed for speed and good workflow.
The engine is very stable and produces very nice looking graphics. Even Cryengine can not beat it's graphical capabilities !
The unreal visual scripting technology (Kismet) can create any level of complexity easily and quickly.
Once you learn the basics you can begin making the games of your dreams with UDK.
The very well built in physics engine (Nvidia PhysX) with softbody and cloth support makes beautiful living worlds possible much faster than with many other game engines.
I prefer the unreal technology above all other game engines.
nice being based on the Unreal Engine technology
We started using UDK about 4 months ago.
UDK certainly is one of the most promising free professional game engines out there and also probably the game engine that collects most of the praises these days. The Unreal Editor is very easy to understand and therefore UDK would be our first recommendation for learning a thing or two about game design !
Finally,Unreal technology for free.
This is a great engine. The community is extremely helpful,especially when you are just starting out. UDK uses the latest in rendering and optimization technologies,making it an extremely powerful and flexible engine. You'll be starting to make your own games, in a very short time !
UDK is powerfull engine. It have great perfomance, and very good render looking. i'm 13 yrs old. UDK is very easy in use, that's why I still in UDK. It doesn't need programming, to create ur own game!. From shooter, to Third Person games and Horrors!. But, if u want to create a RPG like gothic, I don't think that this engine will be great for this. Lots of tutorials! great optimization. Just cool!
We have found UDK to be one of the most easiest,powerful and feature rich programs to use to make games. People who say it is hard propably only spent 1 minute looking at it, you don't learn something that fast. We made an effort to use it and we learnt how to use it in just 8 days!
We advise you to just spend a little time playing around with UDK and you will get it!

UDK - superb package.
UDK is for everyone and everyone will be able to play your games. It's rock stable, performance wise it's also very good and it has several built-in optimization techniques that make it even faster !
There are very good tutorials and documentation. Support is superb too !
Great technology with great support.
If you are a budding game developer then look no further than unreal technology, it is everything you need.Many folks realize that UDK is a world class game engine, complete with modern shader support, a powerful physics engine (PhysX,with hardware acceleration) and an easy WYSIWYG game editor.This is one hard to beat game engine !
If you are looking for a fast development tool, this is it.
And don't take my word for it, visit www.UDK.com and see for yourselves.
completely awesome !
The UDK is one of the best game engines I have come across.Great features,and you do not have to learn a programming language at all.
Huge amounts of support, documentation and tutorials to get you started.
I give UDK 9.5 out of 10.
The best that you can get for building interactive technology.
I picked up on UDK about half a year ago. My frustration with other game engines eventually made me look for different programs. I stumbled on UDK and found it very intuitive. I have found in my experience that the unreal editor has a very intuitive user interface.If you don't want to put to many technical but more artistic effort into your projects, then UDK is for you.
And the forum support is great too.
Powerful,feature rich,and easy to use.
Our little game company has been planning to completely switch to UDK. The best thing about UDK is how quickly we can iterate on our game designs. The game engine lets us concentrate on the art and building the game, not technical difficulties.
The support website has excellent documentation. This includes introductory tutorials, and active forums.
The graphics quality of UDK is truely amazing.
Pathfinding and NavMesh creation for artificial intelligence is also easily set up and is very fast.
badass game engine , good for every type of game genre !
You can make whatever type of game you want with UDK.The engine has a very nice terrain editor etc,etc,...
The dynamic water system is very beautiful too.
The types of HDR and bloom that the Unreal Engine 3 uses is also very beautiful. The fact that UDK now also supports FBX makes it a huge time saver too.
The community is great and a lot of members are contributing tips to everyone.
All in all this is a great game engine !
Ideal solution for beginner and professional game developers !
We are working on a huge game project with UDK.
It is a very stable solution for professional looking games, it has very cutting edge features.
CEO of Rodeon Games.
greatest technologies in one great game engine !
As a student game designer, I've been researching and experimenting with various 3d development packages, DarkBasic, Blitz 3d and Xna to name a few. None have been as simple to comprehend and understand as UDK. The innovative layout of the unreal editor (UnrealED) is amazing.
UDK has an amazing lighting engine. No other game engine can handle soft-shadows like the Unreal Engine does.
As a student developer, I am only new to developing games, however I must say, the learning curve for UDK is rather simple, and I would definately recommend it to anybody needing to speedily develop a project.
UDK is a great deal
I have been working with this game engine for about a month now.The simplicity of this game engine is great, and the features are amazing. Support is fast, responsive,and relentless. Cost is free for the power of the Unreal Engine 3. This game engine does not design the game for you, but allows you to develop almost any genre you can think of from first person shooter to third person rpg. It offers full network support for multiplayer action, big plus ! I'm sure that more developers will discover the capabilities of this excellent product.
Lives up to its name !
The Unreal Development Kit can be a great learning experience for everyone.
The very well integrated visual scripting language (Kismet) allows unexperienced people to get things running quickly.
This game engine offers a great opportunity to see excellent commercial game designs in action !
really love this game engine
I tried so many game engines and when i noticed UDK i quickly moved to it.
It's awesome, excellent graphics options, easy to use and the tools are very complete and useful.
Try it and you will never use another game engine,I promise !
UDK,the way to go !
Right now we are evaluating possible game engines for our upcoming projects here at RadCore games.
We have also taken a deeper look at UDK.
We want to primary develop 3D games for PC and that's what UDK comes with out of the box with great features !
In my opinion, nothing is more worth than that !
I highly recommend the 3DBuzz video tutorials,which are available free for download on their site www.3DBuzz.com.
Community support is very good. I always got an answer within half a day.
Something to stick with.
I have worked (or, in most cases - tried) almost every engine listed here. Among them free engines, commercial engines, RAD tools, AAA engines, like Gamebryo, Jupiter etc. What I hate in many open source engines is lack of documentation, unclear code, problems with importers, lack of features, necessity to reinvent the wheel, problems with integrating third party libraries etc.
I must admit, that UDK is beyond of all above mentioned problems. You can create great games with just only visual scripting with Kismet. UDK supports a good range of 3d/textures formats and you hardly can complain about it.The ScaleForm GFX integration is fantastic,and also FaceFX.
the best technology for our games.
We love this game engine, not only is it very powerful but it is also very flexible.
Handles outdoor and indoor scenes equally well, it is very stable, and performance is increasing all the time.
It is one of the most rapidly evolving game engines we've found, it is constantly being improved and updated.
At the moment it has the best graphics rendering technology available.
There are lots of tutorials for the noob, so its easy to get to grips with.
lots of features and yet easy to use
A very exellent aspect of UDK is the development team. They are very nice, and quick to respond with solutions to any problems you may have.I check the website every day,and more and more people are switching over to UDK every day.
Still a mindblowing game engine
The Unreal Development Kit is essentially a complete game engine. Everything from a 3d engine to visual scripting, including network and sound is included. You really don't need to worry about adding features here, as UDK is based upon some the best of breed technology around.A very well developed and easy to use toolset is included that makes developing (or importing) content a snap.Despite having so many features, it is extremely stable. It runs out of the box, and doesn't require hacks to get it working. As for performance, because its built upon such solid technology, the engine is very efficient and scalable.
