Hello!
As always the first is to make a copy of any modded file, a simple wrong character will crash your sim.
-Open with notepad the planeModel_Interior_LOD00.gltf.
-Inside the .gltf look for: {“name”:“WINDSHIELD”
-Inside it look for: :{“baseColorFactor”:[1.0,1.0,1.0,0.01]
-Delete the last “1”
The disappointing of this is the gauges glass reflection also disappear 
Regards
