CopperBulbEarly
by chenjunfu2
CopperBulbEarly ports the copper bulb block from later Minecraft releases back to Fabric for 1.20.1, so players on the older version can use it.
What it does
The mod brings copper bulb variants and their related advancements into 1.20.1. A fix stops copper bulbs from oxidizing when random tick events fire, so the bulbs keep their original look. The port is meant to keep compatibility with existing schematic and world files, and its resource files use the vanilla namespace, which keeps resource pack compatibility intact.
Both the server and every player need the mod, since it is released for both sides. Earlier builds that were installed on only one side caused missing block ID errors when connecting, which is why the environment is set this way. The mod is released under CC0 1.0 Universal, and its source code and issue tracker are public.
Fabric is the only loader with files, and the mod is published for 1.20.1 only. The latest file is 1.0.3+1.20.1 for 1.20.1, dated 2026-04-20, after a first release on 2026-03-25. No required dependency is listed for Fabric.
