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。

3DMOTIVE DISPLACEMENT VS PARALLAX MAPPING IN UE4

To start off this course, we will be looking at the various ways of displacing textures within UE4. We will then discuss in detail the pros and cons of each method and the best ways they can be utilised for a video game environments. Once we understand the various methods used we will begin the creation process starting with the Height maps. I’ll then talk you through the different methods of creating height maps and the different software available for creating them which will include; using a high to low poly workflow for height maps, creating height maps in photoshop and also generating height maps from images using software like Knald, Crazy Bump and xNormal. After creating our height maps I will then talk you through in detail how to create the individual displacement materials in UE4 which will include; bump offset materials, parallax occlusion materials and tessellation. I will talk you though each node used in detail and ways we can set up an instance material so we can edit our displacement material in real time in engine. By the end of the course you will have a better understanding of the nodes available in the UE4 material editor and be able to utilize them to create much more realistic materials for your video game environments.
