Build your map inside the game. Open /mapeditor, place what you want, export when you are done. This RedM map editor gives you 17,473 in-game props, people, animals and wagons, four export formats, and no framework requirement.
Doors that actually open. Line a door up with the wall using Capture and Align, tick "This is a door", export as ymap, and it works in game with no file editing afterwards. The export also writes ready-made entries for door lock scripts, and doors inside an MLO interior are written into a copy of that MLO's YTYP file.
Proper building tools. Move and rotate gizmo, grid and angle snapping, surface snap, prop-to-prop snapping so pieces join with no gaps, align to slope, drop to ground, a brush that paints props as you drag, scatter up to 500 in one click, 60 steps of undo, and box select across 400 objects at once.
The game's own world is editable too. Click any game prop to take control of it, remove props for everyone and restore them later, or move and delete the game's own people, animals and wagons.
Export and walk away. A ready-to-run resource, a game ready ymap, objectloader XML, or JSON for moving maps between servers. Drop the folder in resources, restart, done, with no editor needed to run it. Works on any RedM server: VORP, RSG, RedEM:RP or standalone. oxmysql is required, and the tables build themselves on first start.
