While at an engineering camp, my friend and i came up with a concept for a map. I plan to have the map enclosed in a canyon, with a village, tunnel, and desert (it will be a payload map). My only mapping experience is with the map tutorial from the June PC Gamer issue. I am going to create a sketchup model before i begin working in SDK, so i will post that when i have finished it. If you can give me any help at all, i would greatly appreciate it.
