Okay, I have made my height map how I want it. I have exported it and put it into the terrain folder. Now when ever I go into map maker, to shuts down my FH. At first it just plain crashed, now it stops responding. I used GIMP, and followed everything that the video tut I watched said. I made sure it was only one layer, all on the background layer. I made sure that it said Add Alpha channel, and when i exported it, I made sure it was .png. Now I have no idea what I did wrong. If anyone can help me, please!
