There is a texture in Soviet Refinery on To The Core, that doesn't render properly. However it renders if player is outside of the building.
- Soviet Refinery on ToTheCore
- Look at doorstep of any door on bottom floor from inside.
- Get outside and look again to compare it with proper texture.
Allied Refinery, as well as any other building doesn't have such issue. Door leading to refinery roof on second floor renders properly from both outside and inside.
EDIT: I've heard that somebody had similiar issue.
