SDXL 2
I made this for the sole purpose of working well with checkpoints like Lustify and Homofidelis SDXL. It's definitely better with them than the previous version. You can lower the strength if needed.
SDXL
strength 0.9-1. put this in negative prompt: ugly, deformed, airbrushed, photoshop, rendered, (multiple people), blurry, child, mouth open
SD1.5
strength 0.9-1. Trained on 768 resolution.
Meant to be used with realistic checkpoints my fav is: https://civarchive.com/models/462596/photonic-fusion
