Well, after they mirror the car, they could add a fuel door, but it is up to the devs. After all, it is their game.
I can try to add it --- Post updated --- Mirror is not a problem anymore.... all they need to do is adding a gas cap ,but it depends on them
The textures are mirrored, going to the bother of remapping them all just for a little body line is pointless.
Actually is not from a shady source, its very clear actually, its from the stagea34 mod for slrr made by PDM-Team and converted to BNG, also its wip, and the fuel door is actually a part of the interchangeable quaterpanels, if i remember was 4 different rear quaterpanels, so it cant be separated without having a empty hole, since the pdm team model didnt has a fuel "hole" model in it.
Oh shit, my bad. I've been seeing so many russian mods around that go into auto-pilot when I see a new mod. My apologies for insulting your work, I checked out the thread you made and it does look fantastic
One possible idea could be to remap only the minimal portion of the body where the fuel door goes, that way you could leave the rest of the car's UV mapping as is! Or just pull a Polyphony Digital and alpha map one on
