I have made a layout for escorting missions. Mission 1: escort important office CEO to the company. There are chalk lines and signs to direct you on your path. FXO vs. X amount of XRGs.
SO4_Escort 1.lyt

Interesting idea, but I'm a bit confused to what it actually is.

Maybe some screenshots or a small video to show how the layout works?

I do have a replay of me doing the setup, but I am not on my normal computer, so you will have to wait awhile.
