FAQ
FAQ
What is the standard hostile mob cap?
In single-player with 289 loaded chunks, the hostile cap is 70 mobs.
How is the cap calculated?
Each category has a constant multiplied by chunks and divided by 289, then floored.
What are the friendly caps?
Creatures cap at 10, ambient at 15, water creatures at 5, and water ambient at 20 per 289 chunks.
Does the cap apply per player?
In multiplayer each player has their own cap in their own spawn area.
Why does my farm produce less than the cap?
Caps only count mobs in loaded chunks; spawn-proofing and despawn rates also matter.
