How to Configure Breeding and Imprinting Rates on Your ARK Server

Breeding in vanilla ARK: Survival Evolved is notoriously time-consuming: raising a baby Giganotosaurus takes over 11 real-world days. Customizing breeding rates creates an enjoyable, balanced ecosystem for your community. However, breeding settings require precise mathematical balancing across two different configuration files.

The Critical Rule: Which File Controls Which Setting?

The most common mistake administrators make is placing all breeding settings in GameUserSettings.ini. In reality:

Setting Key	Belongs In File	Section Header	Purpose
MatingIntervalMultiplier	GameUserSettings.ini	[ServerSettings]	Cooldown period between female dino matings (lower = faster).
EggHatchSpeedMultiplier	Game.ini	[/Script/ShooterGame.ShooterGameMode]	Incubation and gestation speed (higher = faster).
BabyMatureSpeedMultiplier	Game.ini	[/Script/ShooterGame.ShooterGameMode]	Time required for babies to reach adulthood (higher = faster).
BabyCuddleIntervalMultiplier	Game.ini	[/Script/ShooterGame.ShooterGameMode]	Frequency of imprinting cuddle requests (lower = more frequent).
BabyCuddleGracePeriodMultiplier	Game.ini	[/Script/ShooterGame.ShooterGameMode]	Grace period before imprint percentage begins degrading.
BabyFoodConsumptionSpeedMultiplier	Game.ini	[/Script/ShooterGame.ShooterGameMode]	How fast baby dinos consume food (lower = less trough babysitting).

The 100% Imprint Math Equation

When you increase BabyMatureSpeedMultiplier by a factor of \(X\), creatures mature \(X\) times faster. If you do not adjust BabyCuddleIntervalMultiplier proportionally, creatures will reach adulthood before their first cuddle window arrives, making 100% imprinting impossible!

The golden rule of ARK breeding configuration:

BabyCuddleIntervalMultiplier ≈ 1 / BabyMatureSpeedMultiplier

For example, if maturation is set to 10.0 (10x faster), cuddle interval should be roughly 0.1 (every 48 minutes instead of every 8 hours).

Tested and Balanced Breeding Configurations

Balanced Community Preset (5x Maturation)

Eggs hatch in minutes, maturation takes hours instead of days, and babies require 2 to 3 cuddles for 100% imprint:

In GameUserSettings.ini:

[ServerSettings]
MatingIntervalMultiplier=0.2

In Game.ini:

[/Script/ShooterGame.ShooterGameMode]
EggHatchSpeedMultiplier=5.0
BabyMatureSpeedMultiplier=5.0
BabyCuddleIntervalMultiplier=0.2
BabyCuddleGracePeriodMultiplier=2.0
BabyFoodConsumptionSpeedMultiplier=0.5

Fast-Paced PvP Preset (15x Maturation)

Designed for fast weekend breeding projects where large dinos mature in under 3 hours:

In GameUserSettings.ini:

[ServerSettings]
MatingIntervalMultiplier=0.1

In Game.ini:

[/Script/ShooterGame.ShooterGameMode]
EggHatchSpeedMultiplier=15.0
BabyMatureSpeedMultiplier=15.0
BabyCuddleIntervalMultiplier=0.067
BabyCuddleGracePeriodMultiplier=3.0
BabyFoodConsumptionSpeedMultiplier=0.3

Applying Breeding Configurations in DustBowl Warden

1. Open DustBowl Warden and Stop your ARK server.
2. In the File Manager, open ShooterGame/Saved/Config/LinuxServer/GameUserSettings.ini and add MatingIntervalMultiplier under [ServerSettings]. Save.
3. In the File Manager, open ShooterGame/Saved/Config/LinuxServer/Game.ini.
4. Ensure the [/Script/ShooterGame.ShooterGameMode] header exists, then paste your maturation and cuddle multipliers. Save.
5. Start your server. Existing eggs and pregnant creatures will apply new rates upon their next cycle.
