Well, I made my first heightmap following this Youtube video, as far as I know I have done everything right. 513 x 513, grayscale and all. I tried to open it in Feralheart and the game crashed, so I went onto the fix video, did what it said and it still crashed, I don't know why and It is REALLY annoying me, it's happened to me before. I just want to make a map. Any help?
