Unreal Engine4虚幻游戏引擎是一款商业性的3D游戏开发引擎，是Epic数百位工程师、艺术家以及设计师的心血之作。

不过这还只是开始，在C++代码中，你可以看到很多创新之处，比如支持Oculus VR、Linux系统、Valve公司的Steamworks和 Steam Box效果，并且可以使用HTML5在网页浏览器中开发游戏。

虚幻引擎4基于DirectX 11，拥有新的材料流水线、蓝图视觉化脚本、直观蓝图调试、内容浏览器、人物动画、Matinee影院级工具集、全新地形和植被、后期处理效果、热重载(Hot Reload)、模拟与沉浸式视角、即时游戏预览、AI人工智能、音频、中间件集成等一系列全新特性。

Unreal Engine虚幻游戏引擎参与制作游戏有：《逃生》、《DMC鬼泣》、《死侍》、《失落的星球3》、《生化奇兵：无限》、《羞辱》、《战争机器：审判》、《杀手已死》、《勿忘我》、《Papa & Yo》、《忍者神龟：脱颖而出》等等。

视频预览：Surface trails system allows you to capture trails from characters or any other objects on a surface by attaching spherical components to them. As main usage example there is snow landscape demo with walking character and physics objects leaving deformation trails after them. 100% Blueprints.Technical DetailsTrails are captured and stored in some area (configurable) around player's camera, so this system is independent from map size.Attenuation of old trails can be configured (can be set to zero so the trails stay forever inside defined area around camera).Trail shape is defined by spherical components with configurable hardness. So for definition of a box, for example, you need to attach several components to it (components count depends on required accuracity, in example scene there are 8 components per box and 2 components per character foot).Actors are marked as trails receivers by applying special Tag to them.System can be used for big variety of cases (trails on water, grass crumpling, any other surface VFX) by draging one material function into material.Snow landscape example includes photogrammetry based dirt material appearing under the snow.Performance notes:System uses rendering to render targets, so it will affect GPU performance. This can be optimized for low performance platforms by decreasing render target resolution. By default resolution is 2048x2048 and all render targets will cost 24 MB of GPU memory.If you are going to use snow deformation from example for your project, make sure that landscape tessellation also fits your performance budget.Number of Blueprints: 6Network Replicated: NoSupported Development Platforms: WindowsSupported Target Build Platforms: WindowsDocumentation: ExampleMap and tutorial videoAdditional information: Asset is distributed as a complete project (because of necessity to handle user input for demo purpose), however system itself doesn't require any additional project configuration and can be easily migrated.
