So you creared another layer (background) and copied the bath tub/wanda?
Normally yes, before ps 2024 I would have done that, but with ps 2024 used gen fill, from photo with her in the bathtub standing, deleted all background, then made the background template larger to add more details, used gen fill to add garden theme background, got that looking right, then circled where the hot tub will be and gen fill the hot tub, then circled where I wanted bush to be on the fence and on the right side of the image and gen filled that, then made the lights and bubbles in the hot tub myself, then added a lighting filter effect
But one big problem with gen fill, you have to be very careful with how you ask it to gen something, as Adobe have censored and restricted a lot of words that you can ask gen fill to do and if it generates images that have some type of nudity it will remove those images and won't show you, that is why I had to make the bubbles in the hot tub myself, as it was showing the legs as nudity, which I don't agree with specially where you are paying for it monthly as it limits what you are able to do
On another thread,
https://f95zone.to/threads/new-beginnings-in-japan-ch-2-v0-4-4-shikharsfree.148613/post-11603643 I made the got the female mc in a pose from in game and made the sexy santa outfit she is wearing myself, but used gen fill to create a Christmas background after getting the tree where I wanted it and then added the fireplace, gen fill did the rest of the background and then I added the mc I made with her sexy santa costume, I have only been using gen fill for nearly two weeks and this is the first image I made with it, I used After effects to make the fire and tree lights on the gif image but the 2nd one is the normal image
