First shown at GDC 2013, Infiltrator showcases Unreal Engine 4's (UE4) PBR and cinematic capabilities at the time. The project is full of expert-level content to help you learn about all the different aspects of what goes into creating a AAA-quality scene. In the following document we will high light some of the UE4 specific tools that were used to create the Infiltrator demo.
Please note, if you use the Infiltrator assets in a new project with reference lighting, you'll have to make a few tweaks to make the Infiltrator content match your content.
You can find and download the Infiltrator project from the Engine Features Samples section of the Learn Tab in the Epic Games Launcher.
The Infiltrator demo makes uses of almost all of the tools UE4 has to offer. In the following section we will highlight some of these tools as well as provide links to documentation for further reading.
The Matinee Cinematic Tool provides the ability to animate the properties of Actors over time, to create either dynamic game play or cinematic in-game sequences. Matinee is the main tool used to bring the Infiltrator demo from an idea into reality. For more information about Matinee and how to use it, make sure to check out Matinee 及过场动画（Cinematic） .
As with any Unreal-based project the Material Editor was used to create all of the Materials that are being used. However Infiltrator make use of a new way of thinking about how to apply Materials to objects. Instead of using a single Material, Infiltrator uses Material Layers which allow you to mix and match different Materials together instead of just Textures. To learn more about creating, setting up, and using Layered Materials, see 创建分层材质 .
Cascade Particle Editor
The Cascade Particle Editor allows artist to quickly and easily create incredible visual effects ranging from smoke and sparks to effects for pick ups or things the player should be aware of. All of the effects you see in Infiltrator were created using the Cascade Particle Editor. For a complete overview of all the features Cascade offers, check out 级联粒子系统 .
Persona Animation System
UE4's Persona Animation System allows users to create animations for their project using a wide variety of animation data. From using skeletal-based animations to morph-based animations, the animation system enables both simple and complex animation across a wide variety of different characters. For details on how to incorporate animation into your project, please see Persona：骨架网格体的动画 .
Maya Animation Rigging Toolset (A.R.T)
The Maya Animation Rigging Toolset, or A.R.T for short, is a comprehensive toolset that takes a character through skeleton creation, skeleton placement, and rig creation, as well as many animation tools to speed up animator workflow. If you would like to learn more about the A.R.T tools and how to install and use them, check out the Animation Rigging Toolset guide.
