Configure AI Settings on Your The Isle Evrima Server

Last updated: August 17, 2026

This guide shows you how to control AI dinosaur spawning, density, individual species, and migrations on your The Isle Evrima server. AI dinosaurs are a core part of Evrima gameplay — they provide food for carnivores and populate the world.

Enable / Disable AI

  1. Stop the server — Log in to the NolimitHost Game Panel, select your server, and stop it first.
  2. Open Game.ini — In the left sidebar, click File Manager and navigate to TheIsle/Saved/Config/LinuxServer/Game.ini.
  3. Set bSpawnAI under [/Script/TheIsle.TIGameSession]: 
    [/Script/TheIsle.TIGameSession]
bSpawnAI=true
    Set to false to disable all AI spawning — useful for PvP-only or event servers.
  4. Save and start the server.

AI Density

AIDensity is a multiplier controlling how many AI groups spawn around players. This is the single biggest lever for AI performance impact.

[/Script/TheIsle.TIGameSession]
AIDensity=1
ValueEffectPerformance
0.25Very sparseBest
0.5LightGood for constrained servers
1DefaultBalanced
1.5Denser, active ecosystemHeavier
2HeavyMaximum AI population — high CPU/RAM
Warning: High AIDensity values significantly increase CPU and RAM usage. On servers with 50+ players, keep this at 1 or lower.

You can change it live via RCON: aidensity 0.5

AI Spawn Interval

How frequently (in seconds) the server checks whether to spawn more AI:

AISpawnInterval=40
ValueEffect
Lower (20–30)More frequent checks, responsive AI population
40 (default)Balanced
Higher (60–120)Less frequent checks, better performance; AI may feel sparse

Disable Specific AI Species

Block individual AI species without disabling all AI. Add under [/Script/TheIsle.TIGameSession]:

DisallowedAIClasses=Compsognathus
DisallowedAIClasses=Pterodactylus
DisallowedAIClasses=Boar
DisallowedAIClasses=Deer
DisallowedAIClasses=Goat
DisallowedAIClasses=Seaturtle
ClassType
CompsognathusSmall carnivore AI
PterodactylusFlying AI
BoarPrey AI
DeerPrey AI
GoatPrey AI
SeaturtleAquatic AI

Remove a line to allow that species. If the section is absent entirely, all AI classes spawn normally. You can also manage this live via RCON: disableaiclasses Compsognathus,Pterodactylus

Migration Zones

Migration zones move herbivore AI populations across the map. Patrol zones activate carnivore AI areas.

[/Script/TheIsle.TIGameSession]
bEnableMigration=true
MaxMigrationTime=5400
bEnableMassMigration=true
MassMigrationTime=43200
bEnablePatrolZones=true
SettingDefaultDescription
bEnableMigrationtrueEnable species migration zones
MaxMigrationTime5400Migration zone duration (seconds)
bEnableMassMigrationtrueEnable mass migration events
MassMigrationTime43200Mass migration interval (seconds, default 12h)
bEnablePatrolZonestrueEnable carnivore AI patrol zones

Toggle migrations live via RCON: togglemigrations
