Below are three examples of worlds I am happy enough with to export maps to CryEngine. I had one with two little bays that were perfect and of course I did not save the settings and wandered away from it without saving the file. I am trying to get it back before I delve into CryEngine with these.

My favorite of these three for a game map is the Plateaus. It has the flat plateau areas for open world play/building, peaks for interest and I can still build my basalt cliff faces with caves! The cliff details will be built with Zbrush-generated modular pieces.
