What Is an MLO in FiveM?

MLO stands for Multi-Level Object — it's a custom-built interior, building, or map asset for FiveM roleplay servers. Unlike vanilla GTA V, MLOs let you create fully enterable, detailed locations like:

Police stations & hospitals
Nightclubs & bars
Shops & gas stations
Gang hideouts & drug labs
Mansions & apartments
Mechanic shops & car dealerships

If you're running a FiveM RP server, MLOs are the #1 way to make your world feel unique and immersive — and keep your players engaged.

Why You Should Install MLOs on Your Server

Benefit	Why It Matters
Player retention	Custom locations give players reason to explore
Server identity	Stand out from hundreds of generic servers
Roleplay depth	Dedicated interiors for specific RP scenarios
Monetization	Sell or lease premium MLOs to players
Community growth	Unique map = word of mouth & Discord invites

Did you know? FiveVault hosts 2,800+ free and premium MLOs — all compatible with ESX, QBCore, OX Core, QBOX, and standalone. Browse all MLOs →

Prerequisites

Before you start, make sure you have:

Requirement	Details
FiveM server	Any artifact (recommended: build 6016+ for modern MLOs)
Server access	SFTP (FileZilla, WinSCP) or direct file manager
A downloaded MLO	Download from FiveVault
server.cfg access	To add the `ensure` line
Framework	ESX, QBCore, QBOX, OX Core, or standalone

Step 1: Download Your MLO

Go to FiveVault MLOs and pick an MLO that fits your server theme. Most MLOs on FiveVault are free — premium ones start at just $15.

Pro tip: Always check the framework tag. If it says "Standalone," it works on any server. If it says "ESX" or "QBCore," it may have framework-specific config files.

Step 2: Locate Your Server's `resources` Folder

Connect via SFTP or open your server dashboard file manager. Navigate to:

server-data/
└── resources/

This is where all your custom content lives. If you use txAdmin, the path typically looks like:

/opt/ts/cfx-server-data/resources/

Or on a local server:

C:/FXServer/server-data/resources/

Best practice: Create a dedicated subfolder for organization:

resources/
└── [mapmods]/

This keeps all your map mods in one place and makes troubleshooting easier.

Step 3: Upload the MLO Files

Extract the downloaded .zip or .rar file on your computer.
Find the FiveM folder — it must contain a stream/ folder and an fxmanifest.lua file.
Upload the entire folder into resources/[mapmods]/ on your server.

Your MLO folder should look like this:

resources/
└── [mapmods]/
    └── my-awesome-mlo/
        ├── stream/
        │   └── ... (ydr, ytyp, ymap files)
        ├── fxmanifest.lua
        ├── __resource.lua (older format)
        └── data/
            └── ... (config files if needed)

Warning: If the folder is missing fxmanifest.lua or stream/, the MLO will not load. Check your download integrity.

Step 4: Add the MLO to server.cfg

Open your server.cfg file — it's in the root of your server-data directory. Add this line:

ensure [mapmods]/my-awesome-mlo

Or if you placed it directly in resources/:

ensure my-awesome-mlo

Where to put it: Add it after essential base resources like spawnmanager, sessionmanager, and your framework (ESX/QBCore).

Example server.cfg snippet:

# Essential resources
ensure spawnmanager
ensure sessionmanager
ensure mapmanager

# Framework
ensure es_extended

# Map mods (MLOs)
ensure [mapmods]/my-awesome-mlo
ensure [mapmods]/police-station-v2
ensure [mapmods]/night-club-interior

Step 5: Restart Your Server

Now restart your FiveM server. You can do this via:

txAdmin → Resources tab → Restart
Command line → Type restart in the server console
Full reboot → Stop and start the server process

After restart, join your server and teleport to the MLO location.

Step 6: Verify the MLO Loaded Correctly

Check if the MLO is running:

status

Or in txAdmin console:

ensure my-awesome-mlo

If it loads without errors (green text), you're good. If you see red errors, check the troubleshooting section below.

MLO Compatibility: ESX vs QBCore vs Standalone

Framework	Compatibility Notes
Standalone	Works on every server. No extra config needed.
ESX	May use ESX-specific files in `data/` folder
QBCore	May use `qb-target` or `qb-core` config files
QBOX	Similar to QBCore, often compatible
OX Core	May need `ox_target` or `ox_inventory` integration

How to check: Open the MLO folder. If you see folders named esx/, qb/, or ox/ — that's framework-specific config. If you see only stream/ + fxmanifest.lua — it's standalone. Example of MLO files inside folder

Troubleshooting Common MLO Issues

❌ MLO doesn't appear in-game

Solution: Make sure fxmanifest.lua exists in the root of the MLO folder. Check server.cfg for typos.

❌ Invisible walls / can't enter

Solution: The MLO may need room portals. Re-download from a trusted source. Some free MLOs have broken portals.

❌ "Resource not found" error

Solution: The folder name in server.cfg must exactly match the folder name on your server. Case-sensitive on Linux!

❌ Textures / textures missing

Solution: You're missing streamed assets. Re-upload the full folder. Some MLOs require additional dependencies.

❌ Server crash after adding MLO

Solution: The MLO may be corrupted or incompatible. Remove the ensure line, restart, and try a different MLO.

❌ Framework errors (ESX/QBCore)

Solution: The MLO may require a specific inventory or target system (ox_target, qb-target, qs-inventory). Install the required dependency.
