How do I create huge chucked terrain? In MED, I found out that I can create terrains that has 500 vecticles in both directions and triangle size of 100 in both directions. When I load a terrain that has 500 vecticles in both directions and triangle size of 100 in both directions into a program and try to drive a car that came from the A8 beta code called "Knights on Wheels", the car falls off the new terrain beyond the original terrain that has 215 vecticles in both directions and triangle size of 28 in both directions. I wish to create huge terrain for a large city.
