This main model is tuned on the lustify (endgame) sdxl model, trained on a dataset of artistic and tasteful nudes. That turned out perfect (lustify endgame is a great base for this) and is honest some of the best quality nudes you can generate IMO.
The trigger words 'nude, solo' should suffice.
Flux however, is a bit of a mixed bag. Note the flux version is fairly experimental and does not take instructions or generate coherent pictures nearly as well. Afrodite flux is a little better. Faces are more attractive, IMO. It does add some detail to certain areas, but also can add extra limbs and nonsense when too high. Flux is much harder to train than SD.
So for flux variants: Maybe 0.4-0.5. Just to reduce the weirdness.
And use a wet skin lora onto for wet skin, because that didn't come out. It likely does boost things a little though, used this way. Not quite in the way I wanted, but at lower weights it's still meaningful in terms of adding some artistry and beauty. For explicit imagery stick to SDXL lustify version.
