Is the "additional data" you meant are the coordinate? I mean, if valo city uses the "additional data" then there's some kind of calculation/script that manages it. Maybe it's possible to transfer it to the addon maps we usually made.
Also, idk it just my half-guessing, maybe Valo City utilizes something that makes road and the other things such as buildings, ped walks, or even grasslands separable (collision wise, .scx wise or something like that) so the AI will automatically scans every route available and makes it a priority?
