Used version 12 as the base for training to bring it back into photorealism. Trained another NSFW set on SDXL (using Booru tags). Then trained the same NSFW set again, this time using the great Lustify Model by Coyotte as the base.
Both NSFW sets were then merged into the trained photorealism model (0.15 ratio for the trained SDXL NSFW set and 0.1 ratio for the trained Lustify set)
