Yes, it can be confusing.
I'd be more help if I had FH on this computer, but I don't so I'll try to explain this best I can;
You'll need to reset the coding back to how it was. Just open a different preset material and steal the code from inside, then change all the numbers to 6.
Then, just make images, save them as a JPG, and name them;
preset_6head
preset_6body.jpg
preset_6eye.jpg
preset_6tail.jpg
and it should work. If not, post the code here, and someone will help you.
