Hi,
I have tried to import Flakmonkey's new perisope housing into DD's open hatch mod (the old version from GWX). Everything works fine, however, it looks slightly different (specular map missing?) and when the red light is switched on during the night the housing stays the same. No red color

I have no clue what I am missing

I imported all the tgas and the model. Any help/tip would be appreciated. Thanks!
Cheers, LGN1
Edit: That's how it looks:
