MLO Interiors
Free and paid GTA 6 MLO interior mods: custom walkable interior maps (Map Load Objects) that load in when you enter. Enhance your server with custom interiors for restaurants, nightclubs, mansions, garages, police stations, hospitals, fire stations, retail stores, gas stations, hideouts, apartment shells and more. They're packaged as .ymap and .ybn files and installed via OpenIV. Use with Roleplay scripts to give roleplay communities the immersive spaces they need, beyond the interiors that come with vanilla GTA 6.
About mlo interiors mods
MLO is short for Map Load Object - a completely modeled walkable interior that loads in as you enter it. The base game includes only a few interiors you can walk in (your apartment, some mission locations). MLO mods allow you to add hundreds of new interiors: restaurants, nightclubs, mansions, police stations, hospitals, garages, custom hideouts, retail shops, gas stations.
MLO interiors serve as the foundation for any quality roleplay server. Whether you're a cop who needs a police station, an EMT who needs a hospital or just a civilian who needs places to work, MLOs have you covered. Check out the Maps category for the wider map-mod catalog and combine MLOs with Roleplay playstyle scripts for the complete package.
Single-player MLOs work as well - many cinematic and machinima productions use custom interiors as backdrops in Rockstar Editor. Refer to the Cinematic playstyle for related tooling.
Installing MLOs usually involves using OpenIV to install .ymap and .ybn files into the correct RPF archive. The Install Guide has step-by-step instructions for map-mod installs.
Common questions about mlo interiors mods
What's the difference between an MLO and a YMAP?
An MLO is essentially a fully-modeled interior with collision, lighting and props included. YMAP is the file format that loads custom map geometry into the world (used for both interiors and exterior props). Most MLO mods will come with both .ymap and .ybn (collision) files.
Do MLOs work in single-player?
Yes - the majority of MLOs work in offline Story Mode; however, some have been optimized for FiveM streaming. These may have issues loading cleanly without minor adjustments. See the compatibility information on the mod page.
Can I use MLOs in GTA Online?
No. If you load custom interiors in GTA Online, you will be banned instantly. MLOs only work in Story Mode or on private servers (FiveM, RAGE MP, alt:V, upcoming SixM).
How do I install an MLO?
OpenIV is used to inject the .ymap, .ybn and texture files into the correct RPF archive. Full paths can be found in the Install Guide. Some larger MLOs require HeapAdjuster 600 in order to prevent crashing on load.
