This LoRA aims to help with one of the weaknesses of Illustrious:
Correct rear ends and anatomy for ponies!
Trained from images I have personally generated, check out my pony collection here!
Though it does best at rear view shots, it is trained in a variety of poses and positions from different angles!
Helpful starter prompt, but please experiment as you wish, not all may be necessary for every situation:
p0nuts, my little pony, feral, mare, quadruped, anatomically correct, equine pussy, dock, equine clitoris, puckered anus,equine clitoris will give a much more pronounced "winking" effect.
puckered anus will weigh the images much more towards rear views.
For a closed vagina, place equine clitoris and labia into your negative prompt.
It's trained to include teats/crotch boobs, but placing pony teats in your negative prompt should hide/remove them if you prefer:
Notes:
This LoRA helps with Cutie Marks for Illustrious, but unfortunately they can still be inconsistent sometimes. A lot are generally fine, but some are worse than others.
