Quasar MLO Creator turns your FiveM server into a map studio. Every tool runs inside the game: open it with /mlocreator, work in the world you already know and see the result seconds later. No CodeWalker, no Alt+Tab, no restart, and no need to know what a .ytyp or a .ymap is.
Build an interior from nothing: place the entrance on any wall, paint the floor and the walls rise on their own, then add doors, windows, stairs and textures. Furnish it with the MLO Editor, which also works on any MLO already on your server and never rewrites the original file. Props drop where you are looking and a gizmo moves and rotates them.
Outdoors, the Ymap tool places props, parks vehicles with a ghost preview and draws weather zones you can fly into. The Collision Cutter opens buildings Rockstar sealed shut: look at a door, click, build, walk through. Only the door goes, not the wall, and when the game treats the wall as a single piece, one key cuts a door-sized box instead.
Press Build and the map loads live for every player online after a short fade. The Maps panel rebuilds or removes anything you made, and removing puts the original building back exactly as it was. Projects are stored in the database and survive updates.
Works with ESX, QBCore and QBox, or standalone. Requires OneSync, ox_lib, oxmysql and a MySQL database.
