Bonemeal Tweaker
Not bad to the bone!
A highly-configurable modpack utility that modifies the way plants are spawned when bonemeal is applied on blocks, also an efficient surface foliage generator.
Configuration is handled by JSON-based config files per blocks in the config/bonemealtweaker directory. Example for the vanilla grass block (vanilla_grass.json):
{
"blocks": [
"minecraft:grass"
],
"replaceBlock": "minecraft:air",
"adjacentBlock": "minecraft:grass",
"iterations": 128,
"applyMode": "BONEMEAL",
"genDensity": 0,
"biomes": [
"minecraft:plains",
"minecraft:forest"
],
"dimensions": [

"spawnBlocks": [
{
"block": "minecraft:tallgrass[type=tall_grass]",
"weight": 60
},
{
"block": "flowerEntry",
"weight": 20
}
]
}
