How to change hunger, thirst and fatigue in Abiotic Factor

Survival needs use separate speed multipliers in SandboxSettings.ini. A lower value slows the need down; a higher value makes it rise more quickly.

1. Stop the server and open SandboxSettings.ini with Text Editor.
2. Find HungerSpeedMultiplier, ThirstSpeedMultiplier, FatigueSpeedMultiplier and ContinenceSpeedMultiplier.

   

3. Use 1.0 for the standard rate. Values between 0.0 and 2.0 are supported.
4. Save the file and start the server.

For a less demanding server, try modest reductions such as 0.75 first. Setting a need to 0.0 disables its increase and changes the intended survival balance substantially.
