Hi guys, When I played train sim today I found every route in the environment like this, thanks, and I do not know how to solve it. Thanks.
As every DLC brings its own sky and weather, please tell us exactly which route and scenario to be able to reproduce it. And if have you turned on Dynamic Clouds in the game settings (which leads to a different weather engine being used if scenario is set to "3D weather". It seems there is an issue with the skydome model and textures. First thing to do is to verify your game files through Steam.
I don't know this route, and haven't found it on Google. It may need some other DLC, you are missing asset files. Is it a freeware route? Can you give a link?
