It is intented to produce nsfw all on four position.
On this lora, i've been encountered some challenges about ultilizing pussy details, cosine or polynomial didn't do well. Lowering learning R would cost me serious time since i have not enough VRAM and GPU power.
Some of known and impressive SDXL checkpoints without NSFW as expected gave me bad results. There is nothing i can do much for those checkpoints unless they've trained for NSFW.
Some of outputs have been taken from my personal SDXL checkpoint that i haven't published because of some serious polishing and trying new methods.
