I've seen some 3d 18+ themed A.I generated images / stories, but I couldn't find anywhere any guide for it nor what soft to use for that kind of stuff.
Do some of you have some insight about that matter ?
Fastest way.
Create a lora /textual embedding of the person or use an existing Lora/Locon of the subject.
Then use Controlnet and regional prompting to generate them in the positions you want.
