The following guide will show you how to change Incubation settings
If you wish to change any other the incubation times and maturing rates you will need to add the following lines to your Game.ini :
[/script/shootergame.shootergamemode]
MatingIntervalMultiplier=1.0
EggHatchSpeedMultiplier=1.0
BabyMatureSpeedMultiplier=1.0
An example of configuration of these settings would be if you wanted it to be 2 times faster, you would set it to 2.0 instead of 1.0
Please ensure that your server is STOPPED before making any changes to your Game.ini as not doing so beforehand will prevent any changes from saving.
