SeaDome ↔ Grand Meridian Conflict Fix

Why This Fix Exists

Both SeaDome V2 and Grand Meridian ship their own occlusion (.ymt) files. When both resources stream at the same time, GTA V loads whichever gets processed last and silently overrides the other — causing missing walls, holes in the map, or props that render from the wrong distance depending on which MLO won the load race.

This patch is a single merged occlusion set that works for both MLOs at once. You install it into one resource, remove the duplicate copies from both, and the conflict is gone.

Symptoms This Fixes

• Missing walls, holes in geometry, or “see-through” areas in either MLO
• Props popping in or out at wrong distances
• One MLO looks fine but the other looks broken (whichever loaded second)
• Issue swaps between the two MLOs depending on server restart order

Install — 3 Steps

Step 1 — Open the zip and note the filenames

Extract the downloaded seadome-grandmeridian-patch.zip somewhere on your computer.

The files inside are the merged occlusion files you’ll be installing. Keep this folder open — you’ll need to see the filenames for the next step.

Step 2 — Delete those same filenames from BOTH MLOs

Open your server’s resources folder and go into each MLO’s stream folder:

• SeaDome_MLO/stream/
• GrandMeridian/stream/

For every filename that’s in the zip, delete the matching file from both stream folders. Both MLOs currently ship their own copy of these files, and the conflict comes from having duplicates. Both copies have to go before you install the merged version.

Step 3 — Paste the zip contents into one stream folder

Now paste every file from the zip into one of the two stream folders. Either works:

• SeaDome_MLO/stream/   OR  
• GrandMeridian/stream/

Pick whichever one you find easier to remember for future maintenance. Only put them in one folder — putting them in both re-creates the conflict.

Restart the server

Restart the full server (not just the resource). Players who were already connected need to relog for the fix to apply on their client.

Verifying the Fix

After the restart, drive to both interiors:

• SeaDome V2 — bridge, dome interior, aquarium, 360° screens all render fully with correct walls
• Grand Meridian — Bank, Club, Theatre, Rooftop Restobar all render fully with no holes

If either still looks broken, work through Troubleshoot the Fix.

Troubleshoot the Fix

Still seeing holes or missing walls

1. Confirm every duplicate is gone. Recheck both stream folders — every filename from the zip must exist in only ONE folder now (the one you pasted into in Step 3). If you see the same filename in both, delete it from the one you didn’t pick.
2. Restart the full server, not just the resource. Occlusion data is baked at world load — restart alone won’t refresh it.
3. Clear the FiveM client cache. Delete the FiveM cache folder on the client side before rejoining.

It broke something else

Restore your MLO backups from before Step 1, then open a support ticket in Discord with:

• Screenshots of the specific issue
• Your server.cfg (redact secrets)
• A list of every MLO / map resource you have installed

The install boils down to: open zip → delete those filenames from both /stream folders → paste zip contents into one /stream folder → restart server.
