Leave Decay
Chopping down a large spruce or jungle tree with a vein mining datapack is satisfying right up until you look up. The trunk is gone, but a floating cloud of leaves hangs in the sky, slowly ticking away one block at a time. Leave Decay solves that problem by cleaning up unsupported natural leaves after TreeVeinMiner or VeinMiner removes the logs, so your landscape stays tidy without turning your mining swing into a server-crushing canopy scan.
What Leave Decay Actually Does
Leave Decay is a companion datapack designed to work alongside TreeVeinMiner or VeinMiner. When one of those base packs fells a tree, the remaining natural leaves that no longer have a supporting log are handled through a small independent queue. That queue removes the orphaned foliage in an orderly fashion instead of all at once.
The key design decision here is performance. Mining speed never expands into a one-tick canopy scan, which means felling a massive tree does not cause a sudden spike in block updates. On servers and low-end machines, that difference is enormous. You get clean results without the lag spike that usually comes from aggressive leaf removal routines.
Why the Queue Matters
Most leaf decay mods and datapacks simply check every leaf in range the moment a log breaks. That works fine for a small oak, but a 2x2 jungle giant can involve hundreds of leaf blocks. By spreading the work across a queue, Leave Decay keeps tick times stable and avoids the stutter that players notice immediately during fast mining sessions.
Supported Minecraft Versions and Loaders
Leave Decay is distributed as a datapack, so it works on vanilla Minecraft servers and singleplayer worlds without any mod loader. It is built for modern Java Edition releases and pairs with the matching TreeVeinMiner or VeinMiner base pack for the same Minecraft version. Because it is a datapack rather than a Forge or Fabric mod, you do not need to install any additional loader to use it, though it functions perfectly fine in modded environments that already support datapacks.
Version compatibility is the one thing you must respect. The base vein mining pack and Leave Decay have to target the same Minecraft version, otherwise the connection between them will not register. If you are running an older release, check that both packs list that version before installing.
How to Install Leave Decay
Installation is straightforward and takes less than a minute once you have the right files.
- Download Leave Decay and one compatible TreeVeinMiner or VeinMiner base pack for the same Minecraft version.
- Open your world folder and locate the datapacks directory. In singleplayer this is inside your saves folder; on a server it sits in the world directory.
- Place the downloaded Leave Decay ZIP beside the base pack inside world/datapacks. Do not unzip it.
- Run /reload in-game or from the server console.
- Confirm the link with the status command and check that it reports Base connected: 1.
If the status command shows zero connections, the usual cause is a version mismatch or a missing base pack. Double-check that both ZIPs are present and that you actually reloaded after adding them.
A Faster Route Through a Launcher
Players who would rather skip manual file shuffling can grab Leave Decay straight from the foxygame.net launcher, where the add-on catalog lists it alongside compatible vein mining packs and handles the folder placement automatically. That same launcher also keeps Leave Decay updated when a new build drops for your Minecraft version, which removes the guesswork of matching pack releases by hand.
Pairing It With Vein Mining
Leave Decay is intentionally minimal. It does not add new tools, ores, or mechanics. Its entire job is to finish what vein mining starts. That focus is what makes it reliable: there is no configuration screen to fight with, no permissions to set up, and no commands to memorize beyond the reload and status check.
For builders clearing forested terrain, this combination is a genuine quality-of-life upgrade. You swing once, the trunk vanishes, and the canopy follows shortly after in a controlled trickle rather than a laggy avalanche.
Final Thoughts
Leave Decay fills a small but annoying gap in the vein mining experience. It respects server performance, requires only a base pack and a reload, and works as a plain datapack across supported Minecraft versions. If floating leaves have ever ruined the view after a big harvest, this is the add-on that quietly fixes it.
