Basic settings
The very basic settings can be adjusted through the .ini files in the Settings/ folder.
If you are missing those, you should probably go back to First launch.
As of writing this, the folder should contain four files:
InteractionSettings.ini: Controls everything non-backup.BackupSettings.ini: Controls backup settings.LocalizationSettings.ini: Controls UI translation, by default English.PropSettings.ini: Controls prop models, offsets and rotations.
We will not go into detail for those as every setting has a description which explains what it does and what value to input. The value that is already set (if you haven't changed it yet) is the default value.
