ARK: Custom Launch Parameters

If you want to customize your ARK PC server even further, you can do so by enabling the use of Custom Launch Parameters.

Setting a Server Up for Custom Launch Parameters

To setup a custom launch parameter on your server, do the following:

1. In the Control Panel for your server, set the Map drop-down value to "Custom". This will add two new sections to the panel. Conversion ID and Launch Parameters Line.

   
   
   

2. Click the (i) info button next to the launch parameter box to get your parameter line for the desired map. An example of The Island's parameters:

   
   
   

3. Copy the parameters line for the map you were using and add it to the Launch Parameters Line textbox:

   
   
   

If you have mods on your server or wish to modify your server by changing various parameters, you will also need to add these to your Launch Parameters Line.

Adding Mods

When you add mods to your server while using custom launch parameters, you will need to add them in both Mod ID(s) as well as Launch Parameters Line.

1. At the end of the Launch Parameters Line, add ?GameModIDs=
2. Copy and paste the contents from Mod ID(s) directly after the equals sign. Example of using Structures+ and Resource Stacks 2.0.

   
   
   

3. Click on the green button to save settings and restart the game server for the changes to take place.

Command Line Arguments

To change some behaviors on your server, you can do this by adding in command line arguments. List of Command Line Arguments

1. Find a parameter that you wish to change, such as overriding the official difficulty. In the case of this example, we want wild dinos to have a max level of 300.
2. In the Launch Parameters Line, add the following at the end: ?OverrideOfficialDifficulty=10.0

   
   
   

   NOTE: Dino Max Level = OverrideOfficialDifficulty * 30. (10 * 30 = 300)

3. Any additional parameters must be separated by the question mark ?.

   Ex: ?OverrideOfficialDifficulty=10?AllowFlyerCarryPvE=true?MaxPersonalTamedDinos=500

4. Click on the green button to save settings and restart the game server for the changes to take place. If you are modifying the dino levels, you will need to run a Destroy Wild Dinos command. For help on this, visit this page for more information.

Custom Map for ARK

1. Head to the Steam workshop area for ARK and locate the map you wish to use.

   Go to Steam Workshop and click on the Map link on the right under Browse By Tag.

2. Once you find the map you will want to grab the Map ID located at the end of the URL of the specific mod. For example, lets use Crystal Isles.

   Crystal Isles Workshop Page - https://steamcommunity.com/sharedfiles/filedetails?id=804312798

   Map ID = 804312798

3. On the ARK control panel, look for the map ID box. If you have trouble locating it, you will need to switch the map to "Custom."
   
   
   
   
4. Add the value shown above into the Map ID box.
5. On the Launch Parameters Line box, add ?ModMapID=804312798 to the end of the parameter line.

   
   
   

6. Change TheIsland to CrystalIsles.

   
   
   

   NOTE: Most custom maps will list the map name on the Steam Workshop page along with the Map ID value. If it is missing from the page description, it may be listed in the comment section.

7. Click on the green button to save settings and restart the game server for the changes to take place.

Primitive+ or other Conversion Mods for ARK PC

1. After setting the Map to "Custom", the Conversion ID box will be visible.
2. Add the mod ID value for the conversion mod in this field. This is an example using Primitive+.
   
   

   
   
   

3. Click on the green button to save settings and restart the game server for the changes to take place.

NOTE: To join a Primitive+ server, you will need to change your game mode at the main menu within ARK. At the bottom right, there will be an option for Primitive Plus. Click it and allow ARK to restart.
