576x576 worked best for me, which was the res it was trained on. (note: lora name file changed.)

You can also just generate generic pony with the tag MLPThreeD

Manages to make most of the main ponies, but struggles a lot with rainbow dash and mixes things up when doing more than one. Also struggles with the eyes a bit but 1 in 20 outputs seems alright.

Helps to add things like: wings,horn,blue_skin,tail,horse_tail

to the characters it applies to.
