Configure AI Settings on Your The Isle Evrima Server

Control AI dinosaur spawning, density, individual species, and migrations on your The Isle Evrima dedicated server.

AI dinosaurs are a core part of Evrima gameplay — they provide food for carnivores and populate the world. You can fully configure spawning, density, individual species, and migration behavior.

Enable / Disable AI

Stop the server

In the XGamingServer Panel, go to Console and stop the server.

Edit Game.ini

In Files, open TheIsle/Saved/Config/LinuxServer/Game.ini and set:

[/Script/TheIsle.TIGameSession]
bSpawnAI=true

Set to false to disable all AI spawning. Useful for PvP-only or event servers.

Save and start

Toggle AI on/off without restarting:

toggleai

Or set explicitly:

toggleai 0
toggleai 1

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

Value	Effect	Performance
`0.25`	Very sparse	Best
`0.5`	Light	Good for constrained servers
`1`	Default	Balanced
`1.5`	Denser, active ecosystem	Heavier
`2`	Heavy	Maximum 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.

Change live via RCON:

aidensity 0.5

AI Spawn Interval

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

AISpawnInterval=40

Value	Effect
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

Available AI Classes

Class	Type
`Compsognathus`	Small carnivore AI
`Pterodactylus`	Flying AI
`Boar`	Prey AI
`Deer`	Prey AI
`Goat`	Prey AI
`Seaturtle`	Aquatic 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

Setting	Default	Description
`bEnableMigration`	`true`	Enable species migration zones
`MaxMigrationTime`	`5400`	Migration zone duration (seconds)
`bEnableMassMigration`	`true`	Enable mass migration events
`MassMigrationTime`	`43200`	Mass migration interval (seconds, default 12h)
`bEnablePatrolZones`	`true`	Enable carnivore AI patrol zones

Toggle migrations live via RCON:

togglemigrations

Performance Tips for AI-Heavy Servers

If your server is struggling under AI load:

Reduce AIDensity to 0.5 — biggest single improvement
Increase AISpawnInterval to 60 or 90
Disable unused AI classes — removing flying and aquatic AI helps on inland servers
Use wipecorpses periodically via RCON — corpses persist and consume memory
Disable mass migrations if you don't need them: bEnableMassMigration=false

See Server Requirements for RAM and CPU recommendations by player count.
