The only MLO fixer that knows Liberty City

Broken MLO or map? Fixed, with proof.

Players falling through the floor? Textures missing? Upload a FiveM MLO or map. We find the problems, repair what is safe to repair automatically, and shrink oversized textures. Every fixed package is scanned again from its own files before you get it.

Optimization

Faster, lighter, smoother.

A map can work and still drag your server down. We check weight as well as faults.

  • Oversized textures cut down

    Texture files over FiveM’s 16 MB limit are shrunk without re-encoding: we keep the game’s own smaller copies of each texture. Very large files can come back only partly reduced, and your report says so.

  • Less lag and stutter

    Textures that eat streaming memory are slimmed down, so there is less to stream while players drive around.

  • Fewer crashes

    Empty collision parts, missing interior registrations and duplicate files are fixed before your players hit them.

  • Faster load-in, less pop-in

    Map extents that are too small are grown, so props stop popping in late.

  • Hidden rooms skipped

    Interior room and portal counts are corrected, so the game can skip drawing rooms you cannot see.

  • Smaller downloads

    Lighter files mean players download less and join your server faster.

  • Floors and doors checked

    Missing collision and blocked doors are found and shown to you. Empty or misnamed interior collision is fixed automatically.

  • Numbers, not promises

    Your report shows file sizes before and after, so you can see what changed.

Two cities. Any location.

Built for Los Santos and Liberty City.

Most tools only know GTA V. We built MLO Fixer from real Liberty City server work, so LC maps and MLOs get the same checks as LS ones.

What we check

Nine checks. The problems players actually hit.

Falling through the map, invisible walls, flickering walls, floating props, doors you cannot walk through. Each finding names the file and the fix.

  • Collision

    Missing floors, invisible walls, and .ybn collision that does not match what you see.

    How we check collision

  • Geometry & LOD

    Empty drawables, broken model references, and LOD links that make objects disappear at a distance.

    How we check geometry

  • Textures

    Oversized .ytd textures and missing references that waste memory or leave surfaces blank.

    How we check textures

  • ytyp & archetypes

    Invalid .ytyp entries, mismatched model names, and wrong bounds that stop assets loading.

    How we check archetypes

  • fxmanifest

    Missing file declarations and broken paths in fxmanifest.lua.

    How we check manifests

  • Prop placement

    Floating props and misplaced objects in .ymap files.

    How we check props

  • Portals

    Missing or misaligned portals and wrong room links that make walls, props, or lights vanish between rooms.

    How we check portals

  • Occlusion

    Occluders that hide things they should not, or let the game draw everything behind a wall and drop FPS.

    How we check occlusion

  • Doorways

    Doors you cannot walk through: collision across the opening, wrong door bounds, or a frame too tight for the player.

MLO Fixer, a texture optimizer, or a freelancer?

Three ways to fix a broken or heavy FiveM map. Here is what each one does.

MLO Fixer compared with texture optimizer tools and hiring a freelancer
What you needMLO FixerTexture optimizer toolsHiring a freelancer
Finds faults Yes. Nine checks, every problem by file No. Textures and models only Yes, by hand
Fixes faults Safe ones: bounds, interior portals, manifests, empty collision parts, duplicates. Missing props and collision are flagged No Yes, by hand
Texture optimize (16 MB limit) Yes, in every fix Yes Sometimes, often extra
Before-and-after renders Not yet for your own files. Every fix is re-scanned No Rarely
Liberty City maps Yes Textures only Depends on the person
Turnaround Minutes Minutes Usually days
Price From $5 a fix. No credit used if nothing is fixed Free to a few dollars Often $10 to $60 a job

Typical for each kind of option, not any one company. A freelancer can do custom work we do not, like building new rooms.

Pricing

Pay once, or fix files every month.

One fix for one file, or a monthly plan. You only use a credit when a fix works. Nothing to fix? No credit used. The fix fails? No credit used.

FAQ

Before you upload.

More detail in the field guide.

Does it work with Liberty City?

Yes. Liberty City and Los Santos maps and MLOs are both supported, wherever they sit on the map.

Why do players fall through the floor of my MLO?

Usually the collision file (.ybn) has a missing floor or does not match the room. The scan finds it and shows where. A missing floor needs new collision, so we flag it for you. A misnamed or empty collision file is fixed automatically.

How do I fix the “oversized assets” warning?

FiveM shows it when a texture file (.ytd) is over the 16 MB streaming limit. Every fix shrinks those files, without re-encoding, only as far as needed. Very large files can come back only partly reduced, and the report says so.

Why do my MLO textures disappear or turn grey?

This is called texture loss. Oversized texture files are a common cause, and every fix shrinks them. Missing texture references are not checked yet.

Why is my MLO flickering?

Common causes are wrong portals, bad occluders, and the same prop placed twice. The scan finds these and names the file. They are flagged for you to change, not fixed automatically.

Which files can I scan?

Send a FiveM resource as one ZIP. Include fxmanifest.lua and the stream folder with its ymap, ytyp, ybn, ytd, and model files.

What if there is nothing to fix?

Then no credit is used. You only use a credit when a fix finishes with something fixed. If the fix fails on our side, no credit is used either. After you upload, we scan your file and show what we will fix and what we can only report, before any fix runs.

How do I know a fix worked?

Every fixed package is scanned again from its own files. Any repair that did not clear its problem, or caused a new one, is undone. The fix report lists what changed, with sizes before and after, and what still needs you. A walk through your own server is the final check.

Will this fix FPS drops and lag?

It helps with lag that comes from the map itself. We shrink oversized texture files and remove identical duplicate files. We do not promise an FPS number. Scripts and your server host also cause lag.

Do you change how my map looks?

Textures are only shrunk, never repainted. Each smaller texture is the original’s own built-in smaller copy, and never below 512 px. Nothing else you can see is changed.

Can I try it on this website now?

Yes. Walk through the sample scan on this page to see what you get. To scan your own file, buy a single fix or a plan, sign in, and upload it from your account. You only use a credit when a fix works. Nothing to fix? No credit used. The fix fails? No credit used.
