On the Cajon Pass I'm experience strange shadow like artefacts. It looks like the alpha channel textures are bugged. -Rain appears black -Wheelfleng greas pads are solid grey -Inside the cab a lot of textures with text are flickering when sunlight hits them. -With the SD40-2, the ditch light is causing a shadow figure in front of the locomotive. I tested is without mods and engine.ini changes, but that does not make a different. The problem is also visible in the Spirit of Steam route in the smoke, but less frequent. I'm playing on a PC, in timetable mode.
I get the same on Xbox but mainly with the sky gradually turning black as if the universe is being swallowed by the shadows
The route is causing the problem, when I drive the SD40-2 on the testtrack then there are no problems.
