Entity Zoning Supervisor
by eerussianguy
Entity Zoning Supervisor lets a config file decide where and when mobs spawn, applying those rules through the natural spawner.
What it does
Spawn rules are written in config files, so a pack maker can set fine-grained control over which mobs appear, and in which biomes. The mod hooks into the natural spawner, and mobs added through json files are handled by the vanilla spawn manager and still spawn at their normal rate. One file only blocks spawning based on the predicates it is given, while another replaces, denies or filters entity loot drops. Shared rule sets can be saved once and applied again later, which removes the need to repeat the same restrictions in each pack.
The mod is an open source Forge and NeoForge project under the MIT License, with a source repository, an issue tracker and a wiki. Installation requires both sides: the server and every player need Entity Zoning Supervisor. TerraFirmaCraft is an optional dependency that adds its own mobs to the zoning rules when installed. Files cover 1.18.2, 1.20.1 and 1.21.1, with 2.0.0 for 1.20.1 as the latest Forge build and 3.0.2 for 1.21.1 as the latest NeoForge build.
Key features
Config-driven spawning
Mob spawning is controlled through config files, with no code changes needed to set the rules.
Biome-based zoning
Mobs can be allowed or blocked in specific biomes, so each area of a world follows its own mob set.
Natural spawner hook
Rules attach to the natural spawner, so vanilla spawn logic keeps running and only the zoning changes.
Loot drop filtering
Entity loot drops can be replaced, denied or filtered by rule, giving pack makers control over rewards.

Use cases
Pack building
Pack makers can define mob restrictions once, save them as shared rule sets and reuse them across projects.
Who it’s for: Pack makers and server owners who want to control which mobs spawn where, and how their drops behave, without writing mod code.
