How to Configure Your The Isle Evrima Server (Game.ini)
Complete Game.ini reference for The Isle Evrima — server identity, RCON, queue, dynamic weather, humans, growth, AI, mutations, and the EOS Engine.ini requirement.
The Isle Evrima uses Unreal Engine INI files for all configuration. The server must run once to generate the config files before you can edit them.
Server File Structure
| File | Purpose |
|---|---|
Game.ini | All gameplay and server settings |
Engine.ini | Required EOS credentials block |
Critical: Evrima requires the
evrimaSteam beta branch — App ID412680with-beta evrima. The Legacy branch is a completely separate game.
How to Edit Game.ini
Stop the server
In the XGamingServer Panel, go to Console and stop your server.
Edit and save
Make your changes (maintain valid INI syntax), click Save Content, then start from Console.
Many of these settings are also exposed as Startup variables in the panel sidebar — use that for quick changes without editing the file.
The panel exposes the most-used Game.ini settings as one-click toggles: SERVER NAME, PLAYER COUNT, ALLOW REPLAY, HUMANS, ENABLE DYNAMIC WEATHER, RCON / RCON PORT / RCON PASSWORD, ENABLE QUEUE / QUEUE PORT, DISCORD, SERVER PASSWORD, AUTO UPDATE.
Game.ini Reference
Most settings live under [/Script/TheIsle.TIGameSession]:
[/Script/TheIsle.TIGameSession]
ServerName="My Evrima Server"
MaxPlayerCount=100
MapName=GatewayImportant:
AdminsSteamIDs,WhitelistIDs, andVIPsbelong to a separate section —[/Script/TheIsle.TIGameStateBase]. If you put them inTIGameSessionthey will be silently ignored.

WhitelistIDs=76561198000000001
VIPs=76561198099999999| Setting | Default | Description |
|---|---|---|
ServerName | "" | Name shown in the in-game server browser |
MaxPlayerCount | 100 | Maximum simultaneous players |
MapName | Gateway | Active map (currently the only official Evrima map) |
Discord | "" | Discord invite URL shown to players |
| Setting | Default | Description |
|---|---|---|
bServerPassword | false | Enable join password |
ServerPassword | "" | Join password |
bServerWhitelist | false | Whitelist mode — only listed Steam IDs can join |
WhitelistIDs | — | One SteamID64 per line. See Whitelist |
VIPs | — | Steam IDs that bypass the join queue when full |
AdminsSteamIDs | — | One SteamID64 per line. Required for admin/RCON recognition |
bQueueEnabled | true | Enable join queue when server is full |
QueuePort | (auto, e.g. 2466) | TCP port for queue connections — XGamingServer assigns this per instance |
RCON
| Setting | Default | Description |
|---|---|---|
bRconEnabled | false | Enable RCON. Required for admin actions on Evrima |
RconPassword | "" | RCON password |
RconPort | (auto, e.g. 2465) | RCON TCP port — XGamingServer assigns this per instance |
Evrima uses a custom RCON protocol — standard Source RCON clients won't work. See RCON Setup.
| Setting | Default | Description |
|---|---|---|
GrowthMultiplier | 1 | Dinosaur growth speed multiplier. Keep below 20 — higher values break growth |
CorpseDecayMultiplier | 1 | How fast corpses decay |
bEnableHumans | false | Enable human characters (disabled by default) |
bEnableDiets | true | Diet system (carnivore/herbivore food preferences) |
bEnableMutations | true | Mutation system |
bAllowReplay | false | Let players record server-side replays |
Playable Species
AllowedClasses=Carnotaurus
AllowedClasses=Stegosaurus
AllowedClasses=Tyrannosaurus
AllowedClasses=PteranodonRemove a line to block that species. Leave the entire section without AllowedClasses lines to allow all. See Playable Dinosaurs.
| Setting | Default | Description |
|---|---|---|
bSpawnAI | true | Spawn AI critters (carnivore food source) |
AIDensity | 1 | AI spawn density multiplier |
AISpawnInterval | 40 | Seconds between AI spawn checks |
DisallowedAIClasses | — | Block specific AI species from spawning |
bSpawnPlants | true | Spawn plants (herbivore food source) |
PlantSpawnMultiplier | 1 | Plant density multiplier |
bUseRegionSpawning | false | Restrict player spawns to specific map regions |
| Setting | Default | Description |
|---|---|---|
ServerDayLengthMinutes | 45 | Daytime duration in minutes |
ServerNightLengthMinutes | 20 | Nighttime duration in minutes (intentionally shorter) |
bServerDynamicWeather | true | Enable dynamic weather changes |
MinWeatherVariationInterval | 600 | Min seconds between weather changes |
MaxWeatherVariationInterval | 900 | Max seconds between weather changes |
These are unique to Evrima — herbivore AI herds migrate across the map and patrol zones activate carnivore AI areas.
| Setting | Default | Description |
|---|---|---|
bEnableMigration | true | Enable species migration zones |
MaxMigrationTime | 5400 | Migration zone duration (1.5 hours) |
bEnableMassMigration | true | Enable mass migration events |
MassMigrationTime | 43200 | Mass migration interval (12 hours) |
bEnablePatrolZones | true | Enable carnivore AI patrol zones |
Engine.ini (REQUIRED)
Evrima requires Epic Online Services (EOS) credentials in Engine.ini for the server to register with the matchmaker. Without this, your server won't appear in the in-game browser.
[EpicOnlineServices]
DedicatedServerClientId=xyza7891gk5PRo3J7G9puCJGFJjmEguW
DedicatedServerClientSecret=pKWl6t5i9NJK8gTpVlAxzENZ65P8hYzodV8Dqe5Rlc8These are public, shared credentials — every Evrima server uses the same values. They're pre-configured on XGamingServer, but if you've reset your config files you'll need to add them back manually.
Ports
XGamingServer allocates all ports automatically per server instance — you don't need to forward anything. The exact numbers vary, but the protocols and purposes are:
| Protocol | Purpose |
|---|---|
| UDP | Game traffic |
| UDP | Steam query / beacon |
| TCP | RCON (custom Evrima protocol — see RCON Setup) |
| TCP | Join queue (when enabled) |
To see the exact port numbers for your server, check the Startup tab of the panel.
Common Issues
| Problem | Fix |
|---|---|
| Server doesn't appear in browser | Verify Engine.ini has the EOS credentials block. Wait 2–5 minutes after start |
| RCON connection refused | Confirm bRconEnabled=true, password is set, and TCP port 8888 is open. Use a custom Evrima RCON client |
| Players can't join | Check whether bServerWhitelist=true and you forgot to add their SteamID |
| Config changes don't apply | Always stop the server before editing — Evrima overwrites configs on shutdown |
| Growth rate broken | GrowthMultiplier above ~20 breaks the growth system. Stay below 20 |
