A support for facial identity preservation or face-locking.

I think being able to upload an image and have the ability for facial identity preservation and face locking would be ideal and make generating images that much better because it would give the ability to have fully consistent image generation. Still not allowing famous people of course. If someone wanted to regenerate the same demon face they would have that ability instead of getting different faces. Perhaps also an image to image generator. You upload the image and use one of the models (both censored and uncensored) to act as a guidance for the generating model to use so the image matches more closely to said uploaded image.
