The day\/night cycle is one of the most impactful settings you can tune on a The Isle Evrima server. Night isn’t just darker \u2014 it changes hunting behavior, visibility, and how vulnerable each species feels. A server running long, brutal nights plays completely differently from one bathed in near-permanent daylight. The good news is that the whole cycle is controlled by just two keys in your Game.ini<\/code>, and once you understand how they relate to each other you can dial in anything from a relentless survival-horror night loop to a casual all-daylight roleplay map.<\/p>\n\n\n\n

This guide walks through exactly which keys control the cycle, what the numbers actually mean in real-world minutes, several ready-to-paste presets, the ratio math that decides the “feel” of your server, and the restart step that trips up most first-time admins. Everything here is for the live Evrima<\/strong> branch \u2014 not the old Legacy build, which used different files and flags entirely.<\/p>\n\n\n\n

The two keys that control the cycle<\/h2>\n\n\n\n

The day\/night cycle on Evrima is governed by two settings inside the [\/Script\/TheIsle.TIGameSession]<\/code> section of your Game.ini<\/code>. There is no in-game slider and no separate “time of day” config \u2014 these two values are<\/em> the cycle:<\/p>\n\n\n\n

Key<\/th>What it controls<\/th>Default<\/th><\/tr><\/thead>
ServerDayLengthMinutes<\/code><\/td>How many real-world minutes the daytime phase lasts<\/td>45<\/code><\/td><\/tr>
ServerNightLengthMinutes<\/code><\/td>How many real-world minutes the nighttime phase lasts<\/td>20<\/code><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

The critical thing to understand is that these are measured in real-world minutes<\/strong>, not in-game hours. ServerDayLengthMinutes=45<\/code> means the sun is up for 45 actual minutes on the wall clock before the server transitions into night. Likewise, ServerNightLengthMinutes=20<\/code> means 20 real minutes of darkness before sunrise. A full cycle with the default values therefore takes 65 real minutes (45 + 20) from dawn to dawn.<\/p>\n\n\n\n

Both keys live in the same section as your server name, slot count, and RCON settings, so you don’t need to create a new section \u2014 just find or add these two lines. Here’s exactly where they sit:<\/p>\n\n\n\n

[\/Script\/TheIsle.TIGameSession]\nServerName=\"My Evrima Server\"\nMaxPlayerCount=100\nServerDayLengthMinutes=45\nServerNightLengthMinutes=20<\/code><\/pre>\n\n\n\n
A single typo in the section header or key name will cause the server to silently ignore your value and fall back to its internal default \u2014 so copy the casing exactly. If you’ve edited a Game.ini<\/code> before while setting up your The Isle Evrima dedicated server<\/a>, the format will look familiar.<\/p>\n\n\n\n
Where to find Game.ini<\/h2>\n\n\n\n
The file location depends on which operating system your server runs on. The config folder is only generated after<\/em> the server has been launched at least once, so if you don’t see it yet, start the server once and stop it:<\/p>\n\n\n\n
