In the current situation, the level designer needs to do a lot of work to create natural systems like rivers, lakes and mountains. Making changes to a level after is has been designed also involves a lot of work. First the area that will be affected needs to be clearing, followed by actually applying the change. Because most of this work is performed by hand, designing a level therefore costs a lot of time.
This research introduces the concept of environmental features. This concept uses a procedural content generation approach and separates the design of a natural system from its actual creation. Based on this design, and some shape in the level, the final representation of the natural system can be generated automatically. The main benefits of environmental features is that it allows level designers to create and change game levels faster in a flexible and reusable way.
