How to test and profile maps fast

Five‑minute sanity check

1. Teleport to the entrance and enter. 2) Walk every room. 3) Toggle day and midnight. 4) Open and close each door. 5) Check reflections, shadows, and emissives. 6) Spawn two vehicles outside and look back toward the interior. 7) Run with 8–12 players inside for two minutes.

Resmon routine Press F8 → resmon 1

Resmon routine

1. Press F8 → resmon 1. 2) Watch CPU at idle for 30 seconds. 3) Trigger a peak moment: doors, targets, seating, interactions. 4) Record load numbers for each resource. 5) Anything above 0.05 ms sustained in an interior is a flag. 6) Remove one map at a time to confirm the culprit.

Artifact and DLC checks

• If you see invisible walls or “black rooms,” the YTYP did not load. Recheck DLC_ITYP_REQUEST lines and file names.
• If peds cannot move, the navmesh may be missing or door flags are wrong. Test without target scripts to isolate.

Buyer’s Guide for paid MLOs

What to check before you buy

• Portals: rooms seal properly; no see‑through edges when doors open.
• Lighting: no flicker at night; emissives look stable; no overbright glass.
• Navmesh: peds path all rooms; stairs work; doors use correct flags.
• LOD chain: exterior LODs pop cleanly; no late swaps.
• Stream size: under 60–120 MB for small/medium interiors.
• Memory: textures are reasonably compressed; no bloated 8K.
• Collisions: bullets leave decals; you cannot walk through counters.
• Game build: works on your target build without hacks.
• Conflicts: coordinate list provided; compatible with popular overhauls.
• Support: changelog, updates, and a way to report bugs.
• License & escrow: terms are clear; you can configure doors and props.

How to test a paid map

• Spin up a throwaway server. Add only the map and your essential core.
• Run the Resmon routine from above. Save screenshots of idle and load.
• Stress test with 15–20 players. Time at night and rain. Walk every room.
• Try doors from both sides. Use a flashlight in dark corners.
• Place your job props. Check doorway widths and seat offsets.

How to profile like a pro

How to profile like a pro

• Record baseline with the map disabled. Then only the map. Then the full stack. Compare.
• Move closer to the exterior parking and look back inside. Watch draw calls and spikes.
• If the map holds ≤0.03 ms idle and ≤0.07 ms under load, you are good.

Buyer checklist (print this)

Check	Why it matters
Rooms seal with clean portals	Prevents overdraw and FPS loss
Emissives stable at night	Avoids flashing and eye strain
Peds walk stairs and doors	Ensures jobs and AI behave
LODs pop cleanly	Stops texture pop‑in outside
Stream size in budget	Keeps RAM and VRAM headroom
No collision leaks	Prevents exploits and weird movement
Build matches server	Avoids black rooms and crashes
Coordinates + conflicts listed	Saves hours of debugging
Active support channel	Faster fixes and updates
Clear license	You can configure and move props

FAQ: common MLO problems and quick fixes

1) I get a black interior or go through an invisible wall. What now?

• Your YTYP files did not load. Confirm data_file 'DLC_ITYP_REQUEST' lines and file names. Verify this_is_a_map 'yes'.
• Need more help? Check the invisible wall guide here

2) Lights flicker or glass glows too much at night. Fix?

• Switch time to midnight and look at emissives. If the issue persists, disable other post‑FX mods and check for duplicated emissive props.

3) Peds cannot walk through doors or up stairs.

• The navmesh or door flags are wrong. Test the map alone. If it works solo, a target script or doorlock might be the cause.

4) Texture pop‑in when I look toward the street.

• The exterior LOD chain is heavy. Lower texture resolution or ask the author for lighter LODs. Avoid stacking multiple remaps in the same block.

5) I see z‑fighting on floors or walls

5) I see z‑fighting on floors or walls.

• Two geometry layers overlap. Remove other map edits that touch the same coordinates. Keep only one version.

6) Resmon shows spikes when 15 players enter at once.

• That is a stress point at portals and scripts. Reduce dynamic props, disable unused targets, and profile again.
