y Ive pretty much said the same thing. kinda :) "also you could just make the terrain the size you want by using the attributes button.Change the default size to anything you want (within reason)"this is what you ment isnt it? should have put this in last. just made a 10,000 x 3000 x 10,000 single terrain. default is 81.92 x 20.48 x 81.92 no need to tile unless you need the 4x4 format for in game terrains (like for comanche 4 and blackhawk down pc games):)

"Reinstall Windows" is NOT a troubleshooting step.
