Hello everyone! As of the 0.8.5 update this guide is basically obsolete. The devs have added an in game menu for changing your configuration settings. Great news for me as this guide needs far less work. However the .ini file can still be changed out of game. So all the information for finding the file and how to change the settings is still useful. For those of you who want to change them that way continue on to the section "Finding the configuration file." Those who don't, below is a small guide on how to find the settings menu in game and how to use it.

I'm going to take a little time to actually play the new update. This gives me the opportunity to find any bugs with the settings that may pop up. But, eventually I will be adding the descriptions of the settings to this guide so that editing the configs outside the game can be easier by using this as a reference.

Thank you all for the support.

Open the Menu while in game (ESC)

Open Server Settings

At the top of this menu you will see 7 configuration tabs.

General, World, Respawn, Vehicles, Damage, Features, and Custom Zones.

Within some of these settings pages will be a selector called 'Subcategory' that will show you sub-menus within that tab.

For example, when you select the World Tab, the first option in that tab is a selector located on the top right that allows you to scroll through the other windows labeled: NPC, Weather, Map, Cargo Drop, and Hunting.

Within these tab views you can change any of the settings while in game.

To see a short description of the setting you can hover over the title of the setting for about a second. A small description will appear on your cursor.

Settings with an asterisk (*) require you to restart the world. This means you can simply change any settings and exit to the main menu then return back into the game. You do not need to restart the game in order for these special asterisk settings to change.

If you would like to edit the configurations outside of the game, this is how to navigate to the single player settings file.

Navigate to the run prompt or just press windows key + r.

In the run prompt type in %localappdata%.

Then navigate through your files in this order: SCUM>Saved>Config>WindowsNoEditor

In the WindowsNoEditor folder you will find the ServerSettings.ini file.

INI files can be edited in notepad, but I suggest notepad++.

This file is the configuration file for your single player world. This file is shared by all of your characters. So if you wish to play a different character with new settings, you need to come back to this file and change them here.

To start fresh with a new INI file in the game:

• Enter into a single player game.
  
• Navigate to the menu with the (ESC) key.
  
• Select "RESET ALL TO DEFAULTS" at the bottom left of the screen.
  
• This resets all settings.
  
  OR
• Select "RESET TO DEFAULTS" at the bottom left of the screen.
  
• This resets the settings for only the current tab.

To start fresh with a new INI file from the game files:

• First delete the old settings file.
  
• The file is located in: AppData>Local>SCUM>Saved>Config>WindowsNoEditor.
  
• Then start SCUM.
  
• Start a new game with a new character, or load into an old single player character.
  
• A new settings file will be created when the game loads to the main menu.
  
• If you wish, you may now exit the game and change the configs outside of the game.
  
  OR
• Enter into a singe-player game and use the new in game menu to change the configurations.

You should now have a brand new default settings INI.

Within this file you can manipulate the settings of your game by changing the values that come after the "=". Simply save the file after any changes and start your game. Your single player games will now run with these settings.

An asterisk (*) before the config designates that the setting is only available through the INI settings and CANNOT be found within the game menu.

Under the WORLD tab in the subcategory WEATHER. You may fundamentally change how the world works and it's very confusing. If you simply want a little more day time and a little less night time, I suggest changing "TimeOfDaySpeed" to "3" for 2 real time hour days and changing "SunriseTime" to "5.0" for an even 2:1 day/night split and calling it done. For those more inclined, and want more fine control, head on down to the complete explanation and hang onto your butts.

StartTimeOfDay=8.0
This setting changes the world start time the first time you start the game world, per character. The time is set by a 24 hour clock format.

TimeOfDaySpeed=3.84
The MULTIPLIER that determines an amount of time it takes for a single day to pass in game. See section below for a complete explanation.

NighttimeDarkness=0.0
This Setting changes the amount of ambient light at night. -1 for very dark, 0 for default and 1 for very bright. This setting can be changed in decimals. For instance a setting of -0.25 would make the nights a little darker than default, and 0.25 would make them a little lighter.

SunriseTime=6.0
This is the time, in a 24 hour clock, that the sun completely rises on the horizon. Changing this setting will change the ratio of the day and night cycle. See below for more information.

SunsetTime=21.0
This is the time, in a 24 hour clock, that the sun will completely set on the horizon. Changing this setting will change the ratio of the day and night cycle. See below for more information.

---

EDIT 17/03/22 - This section had a major overhaul. The default day/night ratio I had in earlier versions of this guide was incorrect. This information has been updated and I have now found that we can change the day to night ratio to pretty much whatever we want. Apologies that this is a long read, but I wanted to be extra thorough as the math here is pretty interesting.

This is the most confusing part of configuring your single player world. We have to do a little bit of math for this. So just stick with me, I'm going to try to be as helpful as possible here.

The SCUM day has a default time of 6 hours.
This time can be adjusted by a DIVIDER that adjusts those 6 hours, set by the “TimeOfDaySpeed” setting.
The SCUM default day and night cycle are broken up in a ratio of 5:3.
5 parts day : 3 parts night.

To determine a SCUM day length in real time hours we will need a formula to calculate it.

First, you must take the default 6 hours coded into the game and divide it by the TimeOfDaySpeed setting. For this setting we will use Gt as shorthand for ‘game time adjustment’ in our formula.

This will return the amount of real time, in hours, a single SCUM day’s length will be. We will use Rt as shorthand for “real time”.

So our formula looks something like this.
6 / Gt = Rt
Or, Six divided by a game time adjustment will equal the amount of time that passes in the real world.

If we were trying to find the day length from default TimeOfDaySpeed settings (3.84), it would look like this.

First take our formula.
6 / Gt = Rt

Then we apply 3.84 to our game time adjustment.
6 / 3.84 = Rt

Then we divide and get...
1.5625 = Rt

We have found that the real time of a SCUM day length is 1.5625 hours.

Now, to take this further, we want to determine how many of those minutes of gameplay are going to be in daylight and how many will be in the dark.

First we will take the time in hours and change them to minutes. Using the default settings like we did above.

1.5625 hours * 60 minutes = 93.75 real time minutes per SCUM day.

Then we take the 5:3 ratio and apply it to the real time minutes. To do this, first we need to find how many minutes are in a single part of the ratio. And how many parts in total that we need to find. This is pretty easy.

A 5:3 ratio has 8 parts. 5+3 = 8.

We divide our real minutes (93.75) by the eight parts of the ratio.
93.75 real minutes / 8 parts of the ratio = 11.71875 minutes per part

Then we Multiply the per part value to each side of the ratio.
11.71875 per part * 5 (the first factor of the ratio) = 58.59375 day time minutes
11.71875 per part * 3 (the second factor of the ratio) = 35.15625 night time minutes.

~We did it!~

We figured out what it means for the TimeOfDaySpeed to equal 3.85.
1.5625 real time hours per SCUM day
58.59375 day time minutes
35.15625 night time minutes

I don’t know why the devs chose such an arbitrary number, so let's say we want to simplify and even out our play time.

Let's take what we learned and try to customize the day length. Let's make a single SCUM day last only 60 real minutes long. Here we go.

Remember, we have to start this process in hours, so 60 Minutes = 1 hour. We are also solving for Gt, rather than Rt.

Let's get that formula back here again.
6 / Gt = Rt

Now we apply how long we want the day to be by replacing our real time factor.
6 / Gt = 1

Here we do some simple algebra magic to return the value of Gt, rather than Rt. This looks easier than it actually is.
6 / 1 = Gt

Then simply solve the problem, and return the result.
6 = Gt

To make a Scum day 1 real hour long we set the TimeOfDaySpeed to 6.

Next, let's change the Day/Night ratio.

Having a strange ratio of 5:3 doesn't seem even to me, so let's change the ratio to an even 2:1.

Let's look at, first, how to find the default ratio.

The ratio is calculated through a 24 hour clock. The default times use a sunrise time of 6.0 (0600 or 6am) and sunset time of 21.0 (2100 or 9pm).

This means that within a 24 hour time period 15 hours of the day is “day”. 9 hours of that day is “night.” This can also be expressed like a ratio or 15:9. This is then simplified by finding their greatest common factor and dividing. That factor is 3, divide 3 on both sides to get the default ratio of 5:3.

To customize this we must change either the “SunriseTime”, “SunsetTime” or both to get our preferred ratio of 2:1.

Simply changing the “SunriseTime” to 5.0 (0500 or 5am) will change the ratio of time to 16:8. Allocating one more hour to day time, and 1 less hour to night time. This can be simplified by dividing the ratio by 8, making day and night a 2:1 ratio!

So, finally! 60 Minutes divided into a 2:1 ratio.

60 minutes per day / 3 parts of our ratio = 20 minutes per part
20 minutes per part * 2 = 40 Day Time Minutes
20 minutes per part * 1 = 20 Night Time Minutes

We found that to set the SCUM day length to 60 minutes, with a simplified distribution of day and night time hours:
TimeOfDaySpeed needs to equal 6.
SunriseTime or SunsetTime needs to be adjusted by 1 hour to change the ratio from 5:3 to 2:1.
There will be 40 minutes of day time.
And 20 minutes of night time.

There you go and God speed.
