See a FiveM MLO or map resource in 3D, without starting GTA
Resource Viewer opens a FiveM resource (its .zip or its folder) and draws it the way the game places it: the .ymap entities with their .ytyp archetypes, an interior (MLO) with its rooms, portals, entity sets and lights, its exterior, the game props it uses, and its own models with its own textures.
Turn on its collision (coloured by surface), the game's collision round it, the portals and their flags, the lights, the doors and the settings of its scripts, then walk it in first or third person on its collision to feel the doorways, stairs and pavement. Its checks say what would go wrong in game.
How Resource Viewer works
- Drop your resource: its .zip or its folder, an MLO Creator download too.
- Show its collision, portals, rooms, lights and entity sets, and walk it.
- Read its checks, then run the full checks on the tools server.
You get: Free: a 3D look and a walk through the resource, and a report of what would go wrong in game.
Every tool is free to try: 5 exports a day, files up to 25 MB. The paid plans raise the limits. See the plans.
Questions
- How do I test an MLO without starting GTA?
- Drop the resource here: it is drawn as the game places it, and you can walk it on its collision. The tools server also runs its mlowalk check on it.
- Why do I fall through the floor of my MLO?
- Turn on Collision and walk it: a missing floor, or a hole in the copied map collision round it, shows as a fall. Make the interior with the MLO Creator.
- Can I see what I just made in MLO Creator?
- Yes: step 5 has "Preview the download", which opens the zip here without dropping it again.
In GTA Explorer
- GTA V interiors: the game's own interiors, to compare rooms, portals and time cycles with yours
