This Forge mod for Minecraft 1.16+ adds a neat little particle effect to leaf blocks. Users can configure which types of leaf blocks will drop leaves and the frequency that these leaves are dropped at. This is a Client side only mod.

This is a port from Falling Leaves (Fabric) (replacing the configuration gui with datapacks (see below for more info))

Configuration:

You can configure following setting in the fallingleaves-client.toml in the config directory

leafSize: modifies the size of the leaves

leafLifespan: modifies how long it takes for the leaves to disappear

leafSpawnRate: modifies the amount of leaves that are spawning

coniferLeafSpawnRate: modifier the amount of leaves are spawning from conifer trees

dropFromPlayerPlacedBlocks: weather player placed blocks should drop leaves too

minimumFreeSpaceBelow: how much room below the leaves block is needed for the leaves to spawn

disableWind: disable wind effects for the leaf particle

windlessDimension: a list of all dimension types where there should be no wind

1.18

seasonFallRate: a list of serene season fallrate modifier

Datapack:

To define leaves as conifier besides the predefined values here embedded values . You need to create a datapack following the same pattern as the embedded values in data/modid/fallingleaves/blockname.json with the following syntax and default values:

{
  "spawnrate": 1.0,
  "isConifer": false
}
