Figured that most Muv-Luv fortified suit LoRAs available have too many clothing errors, so wanted to train on the Type 99 Fortified Suit from Muv-Luv Alternative Chronicles, using almost solely and exclusively just character sprites and event CGs from volumes 2, 3, and 4. Ended up getting the model so well-tuned to the six girls used in the training data set that it struggled to make other generic girls LOL. I guess maybe it's because I chose "character" instead of "style" or "concept" when training the LoRA on Civitai (I still have no idea what the exact differences are, and have been just sticking to "character" for my previous four models, which work great considering they are actually meant to be clothing *shrugs*)

Notes:

1. The cockpit will manifest itself into the background even after you negative prompt it, because every single event CG used in the training data set is in the cockpit LOL. LoRA at 0.8 weight seems to be able to deal with this though

2. Every generic female you generate will have sidelocks and hair intakes due to 5 and 3 of the 6 girls in the training data having said hairstyles respectively. I have no idea how to deal with this LOL

3. For some inexplicable reason that I do not understand (if you do, let me know in the comments down below!), the CG from Muv-Luv Alternative Chronicles volume 2 all have "covered nipples", which volumes 3 and 4 did not. They were prompted in the training data set according, so make sure to add "covered nipples" into positive or negative prompt accordingly, or you might observe that they would appear when you don't want them to or not appear when you in fact want them to.

tl;dr: Increase LoRA weight if clothing errors start occurring. Decrease LoRA weight if cockpit starts creeping in

Would greatly appreciate it if you could read this before posting! https://civarchive.com/articles/7060/look-both-ways-before-you-crosspost
