Can you make a blank texture with the word 'TO' at the bottom then a BLANK Interstate Shield with no numbers, and a area to put in your own directional at the top for use with the procedural objects mod?

inerstate 5 only goes south/north

I don't know if it's much help, but for realism, but in the US, all North/South highways are numbered with odd numbers and all East/West are numbered with even numbers! Cheers!

Love for someone to write a brief tutorial on how to create these for ourselves!
