CorviCraft Spawn Utility
by JayZX535
CorviCraft Spawn Utility lets server owners set entity spawn rates for vanilla and modded creatures through JSON files.
What it does
The utility reads JSON configuration files that control how often each entity spawns, in vanilla and modded biomes alike. Spawns can be adjusted for existing creatures, and entries can also remove a spawn that already exists. Because the config targets the spawn list itself, a pack can change its creature population without editing any other mod.
The mod is server-side only, so players join a server running it without installing anything. It is published for Forge on Minecraft 1.18.2 only, with version 2.2 as the latest file, dated 2025-03-11. The code is open source under the MIT License, and public links for the source, issue tracker and wiki are available. Prehistoric Spawns (A Fossils and Archeology Revival Add-On) requires it, so it is installed whenever that add-on is used.
