@Stefanoid9343 from my experience the double the double people thing really depends on the model you are using to train with because if it was trained in 512 or you are much more likely to get double people if you go higher than 768 and it's still not always perfect if it was a 768 training. a lot of the newer really good models i have downloaded have specified that you need to specify outfits or you are more likely to get nsfw results. your best bet if you don't want any chance of nude images is to find a model that doesn't produce nsfw images i think. but i am no expert.
