Im not entirely sure how to explain what I'm trying to do but I'll do my best. Im looking to create a plains world with two flatish levels. Imagine a world with plains and mountains. The mountains are very steep but at the top they are fairly flat and look about the same as the plains below. The mountains should be easy to build on top of and so should the plains. It should also be easy to build bridges from one mountain to another. This is what I'm trying to do. Does anyone know how I could achieve this?
