[Bug 91342] Very dark textures on some objects in indoors environments in Postal 2

https://bugs.freedesktop.org/show_bug.cgi?id=91342

--- Comment #7 from acutiator@outlook.com --- I tried taking a screenshot of the game running in windowed mode using the command `DISPLAY=:0 xwd -root | convert - /tmp/FILENAME`, but it only showed the game windows as all black. Any idea why this would be?

Anyways, I just took pictures with my phone of the same door in the foyer to the police building. The one to the outside is very dark/black and the one to the inside (presumably the same texture and physical model) is properly textured/lit.
