just downloaded your cockpit and noticed your visor was mapped to a separate .tex file. when i was first playing around trying to get a transparent window to work i found this impossible, i had to map shape to dash and tex as part of existing steering wheel tex file,
or is it as ,ive just had a thought, youve put youre visor.tex inside the cockpit folder, i think i may have been to slow to try this, i created new textures but never thought to put them in the cockpits folder.
