How to Add a FiveM MLO to Your Server

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	6016 (build 7116) or newer	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:

text

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:

text

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 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-mlo directory 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:

text

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:

text

# 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 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.
