Lol Wolverabid is right, heres a tip for you: first get and use WeU (World Editory Unlimitted) second: once you do, dont use cliffs, youll find that no good terrainer here uses them (unless they abosulutley have to because its like a RPG or something) - Heres how to create all the nice things without using cliffs: set entire terrain to shallow water; Using raise will give you normal ground and lower will give you deep water.
