Skins ext_config does nothing

[I.R.Brainiac]

Helloooo...
I have a skin for the Mazda RX-7 spirit that is almost done.(its my first)
I am having problems with the window banners displaying correctly and not casting shadows.
They do show up but the outside ones are very dark.(inside banner is correctly lit but no colorful shadow)(csp)

I was able to brighten them up fiddling with the materials properties such as ksAmbient and ksDiffuse.But apparently that affected all the cars skins not just mine and when I did a file integrity check the changes were reverted back.(I just want to affect my skin)

I spent days googling and looking at ext_configs and made one for my skin in an extension folder placed in my skins folder.No visible changes.Tried merging my code with the file for this car in loaded but nothing changed.

I tried many variations of this example...
[SHADER_REPLACEMENT_...]
ACTIVE = 1
[INCLUDE: common/materials_glass.ini]
IGNORE_OTHER_CONFIGS = 1
MESHES = GEO_EXT_WINDOWS_SUB0
Materials = EXT_GLASS
FilmIOR = 3
CastShadow = 1
BrightnessAdjustment = 3
ExtraLightsAdjustment = 3
; Material properties:
PROP_0 = ksAmbient, 0.7
PROP_1 = ksDiffuse, 0.7
Is_Transparent = 1
The numbers may be wacky but I at least expected to see something...anything.
Please help,I am beyond frustrated.
Thank you.
