Vein Miner & Preview Data Pack (1.21.11, 1.20.1) – Mine Entire Ore Veins

Vein Miner & Preview Data Pack lets you mine whole ore veins and chop down entire trees with a single hit. It works on vanilla worlds and servers without extra client mods. You can crouch while breaking a block to trigger the chain break, and newer game versions show a visual preview of every block you are about to harvest.

Features:

• Breaks entire ore veins and tall trees at once when you sneak and mine.
• Shows a visual highlight preview on target blocks before you break them in modern versions.
• Works purely with vanilla game mechanics on both singleplayer and multiplayer servers.
• Takes normal tool durability and respects item enchantments like Silk Touch.
• Allows custom ores, tree logs, and diggable blocks through simple in-game functions.

Commands:

• /function uvm:add_ore {b:"block_id"}: Adds a custom block to the ore list.
• /function uvm:add_log {b:"block_id"}: Adds a custom log to the tree chopping list.
• /function uvm:add_dig {b:"block_id"}: Adds a custom block to the diggable list.
• /function uvm:remove_ore {b:"block_id"}: Removes a custom block from the ore list.
• /function uvm:add_ore {n:"modid", b:"block_id"}: Adds a custom block from another mod or namespace.
• /scoreboard players set sneak_mode uvm.config 0: Changes the sneak trigger setting.
• /scoreboard players set system_disabled uvm.config 1: Turns off the vein mining system.
• /function uvm:reset_config: Resets all configuration settings back to default.

How to Use:

1. Hold the appropriate tool in your hand, such as a pickaxe for ores or an axe for logs.
2. Press and hold Shift to crouch.
3. Break a block connected to the vein or tree to mine the whole cluster at once.
