Remix issues - not solved

As the previous post (

https://ideasandbugs.com/p/remix-a-photo)

has been “completed”, I am not sure if you see my remark, so I am writing here again, as I am still having the same issues:

Unfortunately, I do not get proper and consistent results.
My needs:
1. We have photos, taken with persons of our team, wearing our unique and special outfits (no typical shapes).
2. On these photos I need to keep the outfits (clothes and accessories) 100% untouched, so that they show the reals products.
3. I want to change the models to our custom models.

My tests yesterday and today show a inconsistent output, no sticking to the photo that shall be used as a base for the remix, but lots of hallucination.

Could you please help me with a best practice and an example of a prompt how to get that done?

I really like the quality of the output and am ready to go for the year plan, but that request must be solved as this is our main need.

Thanks in advance,
regards
Stefan
