Not really happy with the open crotch underwear LoRA that I found on site, and it's pretty hard to get these naturally except on AcornIsBoning checkpoint (which must have included some of these during training), so I trained my own, using roughly 350 5Mpixels pictures of 6 different models to train one.

Use crotchless with weight of 1 seems to do the trick (check my samples).

Feel free to comment or ask any question and report issues (like models lways having the same face or body,...), as this is my first LoRA !
