yo fly
dude it aint easy, but i read the first 20 pages of the hlep file, was able to make a flat terrain, no map, 3 bases 3 hq's and sucessfully take off from them offline.
just slowly read the whole help file, and try to do the things step by step sort of.
for me the hardest was understanding the red grid lines and how to read them properly. once that was done, getting the joystick working to move around the terrain helped IMMENSLY.
good luck and have fun learning. i know i am.
EDIT> making maps as in clip maps? you have to install the old AH one editor, then make a terrain with the same name of your AHII one, then close, copy and paste 2 of the files (i think elv and typ) into the AH one, then open the terrain back up and "make map"
there is a walk through on this board, or the ah-terrain forum i forget which.
