Recommend seeting at 0.55~0.8, Sampler DPM++ SDE, Steps 25-30 is enough
IMPORTANT NOTE:
1/ Using it is a little bit tricky, for example, if you want to make ass view, i recommend using "from behind" instead
2/ Tricky to use if the size image is 512x768, because data training only for body part, no head or face for this, so recommend to use Facial or Character LorA, or using controlnet open pose for help
3/ Feel free to add lingerie part like thigh highs, garter belt, or garter straps without covering vagina or pussy
4/ Working well with plump, milf body,
5/ Better using realistic or Western beauty bias for this
