Most modern GTA 5 mapping is FiveM-targeted. Singleplayer mapping continues but is a smaller scene. We work through why.

How FiveM ships maps

Servers ship the map as part of their resource bundle. Players download it implicitly when joining. No manual installation. Map only exists while the player is on that server.

This makes maps disposable in a useful way - servers can update and refresh maps without players doing anything.

How singleplayer ships maps

The player downloads a map mod and installs it into their game. The map persists. Other mods may conflict. Updates are manual.

Higher friction, more permanent results, smaller pool of users willing to install.
