Your screenshots seem to demonstrate no normals at all.
Is it still like this in 1.0.86.0 for you?
Make sure you test with identical graphics settings, ultra if possible.
Nb. this is on my mods over the Asobo skyhawk : theses parts are unmodified files (textures, normal details from the original plane) not something I’ve made up myself, but on my own materials and textures, the behavior is the same
I suspect you are testing in different graphics settings condition. (Make sure you have “Dynamic Settings” disabled and similar overall settings)
This is clearly visible on the seat screenshot where the texture resolution is lower than it should be.
You’re perfectly right. I had this dynamic setting probably all along my tests, posting wrong results
The Normal Details looks fine without it (even when not in ultra setting).
They’re not exactly as in msfs2020 but that may be because of the composite layer where scale is quite different.
