Using the same generative fill replacement across multiple images

Did you ever find the answer to this? It is now 2025 and I am wondering the same. 

Not sure if anyone is still looking for an answer, but this is what I found. I generated my background in picture 1, opened picture 2 in another tab on photoshop, I then clicked and drug the ai background replacement to picture 2. When I did this, the generative ai sunset background AND the mast was copy and pasted onto picture 2. CTL + T to "transform" or move around the ai susnet background to the correct place, then click the mask section on the sunset ai and use paintbrush tool to tweak/mask it to blend to your new photo. This worked with my photos I was editing (engagement shoot where the sunset was washed out). If anyone is needing pictures I can see if I can make some up, but not sure if this is still an issue for some.  

I'd like to know the answer to the original question too. I'm an architectural photographer and have an exterior with empty planter boxes in front of the building. I have 3 shots at different angles, so I need AI to use the same plants for each image, but even though I use the same command, it comes up with different plants and is clearly inconsistent across the images. Can we use a reference or source image anywhere in the command?

So @Smarquantte  the way I do it is... before I drop an image I make a background using Generative Fill ... without the object I want to use. After I find the background I want to use I then import my images. That's my way around it. I also save the image so I could use it again if I need to. I hope this helps. 

You can make the source image a smart object and add and resize images in psb. Then run any action on new images. You have no control over gf images

Totally agree, none of the answers match the original issue.
This is what worked for me having a batch of 40 clothing models  shoot with the same (complex) background:
Instead of fixing each of the backgrounds, what I did was select the image with the best background, fixed and enhanced it with AI and removed the model, so I got a clean a model free bg. 
Then I Selected Subject from each other images and drag/droped the models over the background I created. 

Not the most automated solution, but did the job.

I have this question as well.  I have 5 instructional steps shot on white of the same body model in nearly the same pose, just with different arm positions manipulating the product.  I want to change the outfit of the model in the photos, but have the outfits all be the same across the 5 photo sequence.  Again - same (human) model, basically same shot, but just slightly different arm positions, and I want the same business casual look on the model in all the photos.

I was having this dilemma, but what I did was copied the layer that the generative fill was in from my first image and copied that over to my second image. I used a paint brush to blend. 

P.S. this is only like my 3rd time using photoshop in my life but this method worked for me. Hopefully it helps someone else!

We should be able to select from the results. And have a "reuse this fill" option. Then the next frames will be consistent. Adobe please give us this feature. Thanks.

I also want to do this. I have 5 photos of a woman on a wood floor and I want to replace it with the same concrete floor but when I generative fill every image gets a different style or colour of concrete floor.
