How to Add a FiveM MLO to Your Server
Install and configure custom MLO interiors on your FiveM server with this guide covering prerequisites, file structure, server.cfg setup, and testing.
Introduction to Audience: Server owners and developers who already
Audience: Server owners and developers who already operate a functional FiveM instance and want to extend it with custom interior/exterior map assets (MLOs).
1 · Prerequisites
Requirement
Minimum Version
Why it matters
FiveM server artifact
Older artifacts cannot load modern cerulean fx manifests.
Map loader (already built in)
Native by default
No extra plugin needed—FiveM streams map files automatically.
Access to Server
SFTP/SSH + write permissions
You must upload files and edit server.cfg.
Legal licence
Proof of purchase / free‑use terms
EU GDPR & Rockstar policy forbid distributing unlicensed assets.
2 · Download & Inspect the MLO Package
- Source integrity – Prefer vendors with SHA‑256‑signed zips or public Git tags.
- Verify structure – A compliant resource resembles:
my-mlo/ ├─ stream/ │ ├─ *.ydr ↰ (models) │ ├─ *.ytyp ↰ (item definitions) │ ├─ *.ybn ↰ (collisions‑―if supplied) │ └─ *.ytd ↰ (textures) ├─ fxmanifest.lua └─ README.md (optional)
- Create
**fxmanifest.lua**if missing – Minimal template:
fx_version 'cerulean'
games { 'gta5' }
author 'YourName' description 'My Custom MLO' version '1.0.0'
this_is_a_map 'yes'
files {
'stream/**/*.ydr',
'stream/**/*.ytyp',
'stream/**/*.ytd',
'stream/**/*.ybn'
}
data_file 'DLC_ITYP_REQUEST' 'stream/**/*.ytyp'
ℹ️ Standards Resource manifests follow the schema
ℹ️ Standards Resource manifests follow the schema in FiveM docs → “Resource manifest” (commit 20b7b15, 2026‑03‑11)
3 · Upload the Resource
- Connect via SFTP to your server root.
- Navigate to
/resources/[maps]/—create the bracket‑folder if it does not exist. - Upload the entire
my-mlodirectory unchanged. Avoid spaces and uppercase in folder names to prevent Linux path issues.
4 · Register in server.cfg
Append (or replace start) after essential base resources:
ensure my-mlo # loads on boot; restarts automatically on txAdmin soft‑restarts
Save the file and restart the server or execute refresh ➜ ensure my-mlo in the live console.
5 · Clear Cache & Reboot (if needed)
FiveM caches map data. To avoid ghosts of older versions:
# Linux rm -rf cache/* ./run.sh +exec server.cfg
Windows (PowerShell)
Remove-Item -Recurse -Force .\cache\* run.cmd +exec server.cfg

6 · In‑Game Verification Checklist
Check
Command/tool
Pass criteria
Teleport
vMenu → Misc → Teleport → Enter Coords
Player spawns at the new interior/exterior.
Texture integrity
profile_frame then walk around
No pink/white placeholders; FPS loss < 10%.
Collision
Walk walls & ramps
No invisible barriers or falling through floor.
Lighting
Timecycle change with /time 23 0
Interior correctly darkens/brightens without artifacting.
If any failures occur, revisit file list—missing .ytd
If any failures occur, revisit file list—missing .ytd or .ybn is the usual culprit.
7 · Streaming Multiple MLOs Safely
- One resource per MLO. This sidesteps hash collisions.
- Prefix names with vendor tag, e.g.
bh-bank-lobby, for easier disabling. - Use identical manifest version across all map resources to avoid parse warnings.
8 · Troubleshooting Quick‑Ref
Symptom
Likely Cause
Resolution
Console: Couldn’t parse manifest
Bad Lua syntax
Run lua -p fxmanifest.lua locally; fix quotes/commas.
MLO visible, textures missing
.ytd files not referenced
Add them to files{} or place in stream/.
Players crash on join
Duplicate prop hash across maps
Rename duplicate .ydr or unload conflicting resource.
Long download time
Large .ytd textures
Compress textures (DXT5 / BC3) or downscale.
9 · Compliance & Data‑Protection Notes
Regulation / Policy
What you must do
Rockstar Modding Policy (2015‑09‑15)
Do not sell assets containing Rockstar IP.
EU GDPR Art. 44‑49
Store vendor invoices; disclose asset origin on user request.
FiveM ToS §3.2
Keep credits intact; don’t redistribute paid mods publicly.
Conclusion
Upload → ensure → restart; if the manifest is valid, your new interior is live within two minutes.
