The Example Levels for Unreal Engine 4 (UE4) have been built to help you quickly get up to speed with a variety of different techniques and artistic applications for building your own games. This document overviews the process of using these examples in the most effective manner along with their corresponding documentation.
It will help if you think of each example level as an interactive museum or science exhibit. Along the walls of each room, you will find any number of demo stations, at each of which you will see various applications of the topic at hand. For example, in the Effects Gallery example level, you will see a different particle effect at each station. These stations are numbered and labeled so that you can easily cross-reference the corresponding documentation for how that particular effect was achieved.
