Chat Command:
/MES.Settings.Creatures.EnableSpawns.Value
Description:
This setting allows you to Enable or Disable All Encounters from this Spawn Type.
This setting allows you to override the vanilla creature spawner so MES is exclusively responsible for spawning creatures / bots. This option has the same effect as loading the Planet Creature Spawner mod.
This setting allows you to set the maximum altitude from the planet surface that a player must be within in order to be eligible to spawn a creature / bot encounter.
This setting allows you to set the maximum amount of attempts that coordinate generation for creature spawning will be attempted for areas where they may have difficulty spawning.
