Okay so the other day I made a Height Map, PNG,grayscale, and saved it right to the terrains file. But when I opened the map maker and typed the file name in it says FH has stoped working correctly -_- Now yesterday I made one with the same PNG,gray scale, but it was for test so I didn't draw much on it and it WORKED O.O. Now I'm really ticked off and I don't know were I messed up at.....
More info: I used GIMP, and my computer is very new I have had it for a month now.
If it's easier I can make a video on Youtube so you guys can tell me were I went wrong.(of me making the map)
