Well, here goes my another attempt at LoRA. This LoRA is based on older style of the artist duo who worked under alias Oono Tsutomu (real names are Hayasaka Yuuki and Hiroe Hiroaki). They are known mostly for their hentai works.
I trained this LoRA on game CGs from games D'ark and D'ark Gaiden.
Attention!
0) Preferable weights 0.6 - 1.0 (depends on checkpoint and other LORAs used in generation)
1) No additional tags needed for using this LoRA. Just add and it's ready to go.
2) It displays artist style even with score (for Pony) and quality (for Illustrous) tags.
3) As my testing shows, this LoRA works with every checkpoint. If you want to use this LoRA on other checkpoints, then you should adjust the weight of this LoRA (0.8 is good enough for most cases).
4) Yes, you can use it to generate hentai images on Civitai.
5) I advise you to use hires-fix. Adding tag for eye color also makes faces better.
