emp_mvalley (download available) Hi again , I started with the dirty work he he, I'm going to show you the final layout and the first in-game shot. Orange means concrete bridges, the dam, and a big rock (called "butt") in central area. Yellow are small hanging bridges only for infantry, black are crossing zones for vehicles in lower part. Map size is 60000x60000, that means 3/4 of the map (just the non playing area around the marked zones) will be in the 3dskybox This is world machine, the app someone mentioned in the past thread, it's great for simulate terrain erosion. Most of those details are missed in the source terrain, but helps anyway. This shot doesn't represent the final quality in any way, but it's a good (and fast) start. The distances aren't final, to import all the data I needed to scale the map to half size. Now I need to expand it again (x2, x and y coord) and cut the 3dskybox part.
