So I used GIMP, made sure I had everything right (513x513, grayscale, ect.) and made a map. When I saved, I saved it as a PNG file, and the name DID say ___.png
BUT, when I went to download the height map, it said '___.png not found!' For the past day, I've been making millions of Height maps but NONE of them will load! Please help!
Also, if the problem still isn't solved, could one of the admins tak the file and make it a map and then give me the code?
