How to Configure the Day/Night Cycle on Your The Isle Evrima Server

Last updated: August 17, 2026

This guide shows you how to adjust day length, night length, and dynamic weather on your The Isle Evrima server. The day and night cycle length is fully configurable — lengthen days for more activity, shorten nights for casual servers, or even run permanent daylight.

Change Day and Night Length

Stop the server — Log in to the NolimitHost Game Panel, select your server, and stop it first.
Open Game.ini — In the left sidebar, click File Manager and navigate to TheIsle/Saved/Config/LinuxServer/Game.ini.
Set the cycle lengths — Under [/Script/TheIsle.TIGameSession], set durations in minutes:
```
[/Script/TheIsle.TIGameSession]
ServerDayLengthMinutes=45
ServerNightLengthMinutes=20
```
Save and start the server from the Console.

Settings Reference

Setting	Default	Description
`ServerDayLengthMinutes`	45	Daytime duration in real-world minutes
`ServerNightLengthMinutes`	20	Nighttime duration (intentionally shorter than day by default)

Common Configurations

Default (Balanced)

ServerDayLengthMinutes=45
ServerNightLengthMinutes=20

Long Day, Short Night (Casual / Active)

ServerDayLengthMinutes=60
ServerNightLengthMinutes=10

Equal Day and Night (Realistic)

ServerDayLengthMinutes=30
ServerNightLengthMinutes=30

Very Long Day (Max Activity)

ServerDayLengthMinutes=120
ServerNightLengthMinutes=5

Note: Very short night values (under 5 minutes) may cause issues for nocturnal species like Troodon that rely on darkness for stealth and hunting bonuses. Consider your player base before eliminating night.

Dynamic Weather

Dynamic weather changes independently of the day/night cycle. Configure how often the weather varies:

[/Script/TheIsle.TIGameSession]
bServerDynamicWeather=true
MinWeatherVariationInterval=600
MaxWeatherVariationInterval=900

Setting	Default	Description
`bServerDynamicWeather`	true	Enable dynamic weather changes
`MinWeatherVariationInterval`	600	Minimum seconds between weather changes
`MaxWeatherVariationInterval`	900	Maximum seconds between weather changes

To disable dynamic weather entirely (always clear):

bServerDynamicWeather=false
