ARK: How to edit spawns (Basic)
How to reduce the overall number of Spawns.
How to stop a type of anything from Spawning.
How to replace one Dinosaur etc with another.
How to limit the spawns of a specific Dinosaur etc.
Dino Name Tag and Entity ID can be found here https://ark.gamepedia.com/Creature_IDs
The default location of your Game.ini and GameUserSettings.ini files is C:\Program Files (x86)\Steam\steamapps\common\ARK\ShooterGame\Saved\Config\WindowsNoEditor
Limit overall spawns changing the line DinoCountMultiplier=1.000000 for example 0.400000 is 40% of the default. 2.00000 would be double the default number of Spawns, untested.
Disable a spawn with NPCReplacements=(FromClassName="MegaCarno_Character_BP_C",ToClassName="") where MegaCarno_Character_BP_C is the Entity ID of whatever you want to remove.
Replace one type with another with NPCReplacements=(FromClassName="MegaCarno_Character_BP_C",ToClassName="Ant_Character_BP_C"), here Ant will replace MegaCarno, use Entity ID.
DinoSpawnWeightMultipliers=(DinoNameTag=Scorpion,SpawnWeightMultiplier=0.5,OverrideSpawnLimitPercentage=true,SpawnLimitPercentage=0.01) will limit the Scorpion spawning to 1%. The chance of a Scorpion spawning at all is done using the SpawnWeightMultiplier=0.5. See the video for a full explanation.
