Bonemeal Tweaker
by ACGaming
Bonemeal Tweaker changes how bonemeal works on Forge 1.12.2, letting server owners control which blocks grow and what spawns.
What it does
Bonemeal applied to blocks can be reshaped through a set of configurable options. A foliage generator decides which plants appear, how dense they are, and whether an optional block is placed above the target block. Blocks that implement IGrowable get full support, and custom bonemeal logic can be applied to the rest.
Bonemeal can act on the natural surface, on world generation, or on both, set by the applyMode option, which defaults to SURFACE. World generation mode also needs a generation cycle count. Optional whitelists limit the effect to chosen biomes and dimensions, and an empty list allows all of them. The project was built for Minecraft 1.12.2 at the request of a commissioning party.
Bonemeal Tweaker runs on Forge and is published for 1.12.2 only, with 1.3.0 as the latest file from 2026-03-30. The server is required and the client is optional, so players may skip it. The code is under the MIT License and the source is open source.
Key features
Configurable bonemeal effects
Server owners set how bonemeal modifies applied blocks, including the efficiency and surface behavior.
Foliage generator
Plants spawned by bonemeal are controlled by density settings and an optional block placed above the target.
Growable block support
IGrowable blocks receive full support, and other blocks can use custom bonemeal logic.
Biome and dimension whitelists
Optional lists restrict where bonemeal takes effect, and leaving a list empty allows every biome or dimension.
