Cars interior shaders completely black and won't change

[Dailydriver]

This is a private mod I gave up on a long time ago for this very reason, the interior is black and doesn't change no matter what kind of values I enter, I have changed the shaders, copy and pasted values and textures that are somewhere else on the car, but the interior isn't changing. It is a shame that this car is basically unusable in first person, everything else is as quality as I can make it.

Since I buy a new PC with RTX 2060 I have same problem with some parts of some cars..
With old PC -> reflet Ok, with new PC -> totally black.
Low & medium shader level is Ok

You find a solution ?

Thanks you

well, I figured out my issue with car textures when I made my own cars, I needed some normal map textures and different shaders in KS editor, I haven't changed my PC so, I will try to help you, but don't think we have the same problem

So I open all 3D models where I have the problem and copy and past material from the one I haven't the problem and it works... don't understand
