To create a custom sign, you can follow these general steps found in community tutorials like this YouTube guide :
: Save your design as a .tga or .dds file to ensure the game can read it.
If you have a file named OMSI-2.rar , it is likely a compressed archive containing a mod (a bus, map, or set of textures). To use it: Extract the contents using a tool like 7-Zip or WinRAR.
Place the extracted folders (usually Vehicles , Maps , or Sceneryobjects ) into your main installation folder.
: Move the finished file into the Texture folder of the specific bus you are using (located within the OMSI 2/Vehicles/ directory).
