vehicle_paint6 how to use it properly?

[Zen-Imogen]

so basically I tried almost everything, and still, it doesn't work. I tried to copy the UV1 map to UV2, and still doesn't work.

UV1 AO Map

UV1 Dirt Map

UV1 Specular Map

UV2 Livery

UV2 Normalmaps

Ingame Picts (case 1, the specular map isn't properly mapped in-game (but ZMod shows it's mapped))

Ingame Picts (case 2, the normal map isn't properly mapped in-game (again, Zmod shows it's properly mapped.)
