I noticed some sights are 32x32 and others are 128x128 and I can pick and chose which ones I want to use, I understand that and have done that for different AC. My problem is when I try creating my own or alter someone elses to my liking it doesnt work. It's displayed as an all black gunsight. I've tried saving them as 'indexed' and 'RGB' .bmp's but I'm doing something wrong. Any help would be appreciated.
btw I'm using whats called "The Gimp" but I'm going to try paintbrush next.
