For best outputs and usage:

Sampler: DPM++ 2S a

Steps: 12, cfg 2.5, CLIP skip 2.

VAE: none required.

Pos prompt: start it with "score_9, score_8_up, score_7_up, realistic, masterpiece, best quality, high quality, highres". The model may need weights when naming the different sex positions.

Neg prompt: "score_6, score_5, score_4, worst quality, low quality, bad anatomy, bad hands, missing fingers, fewer digits, source_cartoon, 3d, blurry, deformed hands, sfw". Also careful with the negatives seems too much can make it worse.

Checkpoint Merge.
