It's best at low weights, with accompanying keywords, so when models do get naked they're not saggy.
It probably has no effect on clothed models, and yes, you must include it in your prompt in order for it to work (saddened I must tell you this).
It does not bias towards asians. Chilloutmix just happens to be very good at them. The models used are all white since v1.0.
This is a fairly strong LORA best used in conjunction with low weights and other keywords like "naked".
Very high weights can cause the perspective to shift down as all the images crop out the face.
Adding "small breast" or "huge breast" can add more size variation, keeping the shape.
Adding stubborn loras or conflicting terms (e.g. "shirt") to the prompt can burn the image.
