I dont really know if it is a bug, but the armored window reflects sunlight, even when there is no path to the sun. (like on a bridge with the whole ship in the way) first i thought its because i had the glas the wrong way, but flipping it did not solve it.
All reflective glass does this. It reflects the skybox and terrain since reflecting the base would probably be too intensive.
Is there annything that can be done with config settings? I would even turn all reflections off if this one goes away! (tryed the different reflection settings, but nothing changed)
