In my opinion the older shiny and chrome versions are my favourite out of all of them. But I’m sure you could contact a support staff to further talk about this issue.
Btw, as far as I know, every single aircraft got included in the new textures package. You might not notice that, but if the visibility is at 49km or less you’ll see the fuselage or every plane turns a bit orange, which in my opinion, looks samazing
Why do I feel like this is actually a change in how sunlight is rendered rather than the brightness of the textures?
Anyways I think the point is actually to standardize the rendering between different aircraft, probably in preparation for some project metal options in the future.
