Mob Compack
by call13
Mob Compack adds biome-fitted mobs to Biomes O' Plenty, placed in the environments they belong to rather than scattered across the world.
What it does
Mob Compack targets the biome mods of the modded overworld and nether, where the call13 team found that mob life was thin. Each addition is made to suit a specific biome, so creatures appear where their look and behavior fit, and new items stay limited to what those mobs drop. The mod builds on Biomes O' Plenty, which is required, and also depends on Fabric API and Geckolib.
Spawn behavior can be changed through a configuration file, which lets a server owner disable any mob or set a different spawn weight for it. Crystalline Chasm from Biomes O' Plenty is one of the places the additions target. Mob Compack runs on client and server, so the server and every player need it. It is published for Fabric, Forge and NeoForge, with files for 1.18.2, 1.19.2, 1.19.4, 1.20.1 and 1.21.1, and is not open source; it is released as All rights reserved.
Key features
Biome-fitted mobs
Mobs are designed for particular biomes, so each one appears in the terrain it was made to inhabit.
Configurable spawns
A configuration file disables individual mobs or sets a different spawn weight for each.
Limited item additions
Additions are restrained, and the few new items come from the mobs that drop them.
Nether and overworld coverage
The additions begin with the modded nether and extend to overworld biomes in later updates.
