well, im not sure if this will help but heres how i made my first preset:
1. i took a look at the included preset files to get the information i needed
2. after hours of playing around i found the following things should be done in able to view your preset (if you dont use gimp then im not sure what you do)
1. the pre made presets were in rgb color, 512x512, jpg. files, and labeled with something such as whats in this example:
the head part was called "preset_1head
the eyes: "preset_1eye"
tail: "preset_1tail"
mane: "preset_1mane"
hope this helps you any!
