POI Population Director

WHAT IT DOES

POI Population Director helps VEIN’s existing zombie spawning system start working on likely destinations before the player arrives. If your route changes, the Director can shift its attention toward the new approach.

The aim is to reduce the empty-arrival delay. Rather than beginning all population work only after you arrive, VEIN’s native spawner receives earlier opportunities to populate the area while it is still being approached.

In testing, this generally produced earlier and more settled arrival populations. Results still vary between locations depending on streamed spawnpoints, native eligibility, available population-cap space and VEIN’s own spawning decisions.

The Director works through VEIN’s existing:

• []Authored AI spawnpoints[/]

  []Location-specific zombie pools[/]

  []Spawn eligibility and filtering[/]

  []Configured population cap[/]

  []Native spawning, virtualisation, cleanup and despawn systems[/]

It does not directly create zombies, guarantee that a request produces a zombie at the exact selected point, increase the configured population cap or replace VEIN’s normal spawning system.

It provides destination-aware spawn requests while leaving final population and placement decisions to the game.

EFFICIENT BY DESIGN

The Director issues spawn requests only during sustained travel and a bounded arrival-recovery window.

Once the trip and arrival window have ended, request activity stops and the mod returns to lightweight idle monitoring. It does not continuously rescore destinations or keep requesting spawn point activation while you remain at one location.

INSTALL 

(If updating from an older version, delete the existing folder first)

Requires a working VEIN-compatible UE4SS installation.

Close VEIN.

POIPopulationDirector folder to:

...\Steam\steamapps\common\Vein\Vein\Binaries\Win64\ue4ss\Mods

Confirm that the final structure includes:

...\ue4ss\Mods\POIPopulationDirector\Scripts\main.lua

Launch VEIN.

UNINSTALL

Close VEIN.

...\ue4ss\Mods\POIPopulationDirector

The mod does not make permanent changes to saves.

COMPATIBILITY

• []Works with vanilla spawning settings.[/]

  []Compatible with spawn-distance modifications.[/]

  []Respects the live spawn-cap multiplier and resulting population cap.[/]

  []May conflict with other UE4SS mods that directly control AI spawnpoint activation or perform similar destination-based population management.[/]

  []Multiplayer and dedicated servers are untested.[/]

  []A VEIN or UE4SS update may require a new version.[/]

  []If VEIN crashes after an update, disable or remove the mod before troubleshooting.[/]

  OPTIONAL VISIBILITY SETTINGS

  To disable crawler and lying zombie spawn postures, add the following to the bottom of:

  ...\Steam\steamapps\common\Vein\Vein\Saved\Config\Windows\engine.ini

  vein. AISpawner. ZombieCrawlerPercentage=0

  vein. AISpawner. ZombieLayerPercentage=0

  If the file already contains a section, add only the two setting lines beneath the existing section rather than creating a duplicate heading.

  These settings are optional and are not changed by the mod. They apply globally and make spawned zombies use upright postures more consistently, which can improve visibility and reduce crawler or floor-level pop-in. Admin setting slider for walker % then divides between mostly walkers and runners.

  NOTES

  • []Does not increase zombie caps.[/]

    []Does not alter native respawn or despawn rules.[/]

    []Cannot guarantee a fixed zombie count or immediate saturation at every POI.[/]

    []A short arrival-recovery pass may submit several native spawn requests when nearby population is low.[/]

    []VEIN still decides whether those requests produce zombies and where they are realised.[/]

    []Do not run multiple versions simultaneously.[/]
