piglin
A mod that let zombified piglins spawn in every nether biome in the same amount as in nether waste biome
piglin makes zombified piglins spawn naturally in every Nether biome at the same rate used in Nether Wastes (weight 100, groups of 4). Nether Wastes keeps its vanilla entry while other Nether biomes gain the same spawn entry.
Requires Fabric Loader and Fabric API for Minecraft 1.21.1. Install on the server (and on clients if connecting to modded servers) and the spawn distribution updates automatically; no commands or config are needed.
Works with modded Nether biomes detected by Fabric’s Nether selector. If a biome already spawned zombified piglins at a lower rate, this raises them to Nether Wastes levels. Should future balance changes be desired, adjust the spawn weight or group sizes.
