Hello, how do I make the "Mod" tab appear in my menu? I created the "mod" folder - lowercase letters - in the ETS2MP folder, added the files to it and started the game. Snow falls, but terrain and physics remain normal. I read a lot about this "Mod" tab but did not know where it was, until in a video I found out where it was. But it does not appear here. Does anyone know how to proceed?
