Introduction

We've seen how to build levels using BSP and meshes. This is really great for man-made structures, such as office buildings, houses, and floors, which are all made of things that look similar to each other. However, things outdoors are very chaotic, with changes in elevation and randomness everywhere. To help facilitate that, Unreal has tools such as Landscapes that allow us to create massive worlds that our players can interact in.
