Heh, heh, heh 
It’s the Unreal Engine 3 default material. It’s likely something went wrong with that window material.
Yeah they have been modifying their servers to run both the PS4 and PC multiplayer game. Lots of patching and I do notice the materials and shaders look really bad after major patching and then it gets better again. At one point there was only indirect light in the game. All direct light and shadows were screwed up but they got it to work again. On the Hard suit Labs website they are looking for both U3 and U4 developers. So looks like they are trying to switch over to U4 from U3 with which the original game was built. Must be hard to change things over from Unreal Script to C++ or maybe not I am not sure 
Ah, BL… I used to play that… feels like forever ago
