About this Mod
Molten Veins
Tired of hauling raw ore back to your furnace? Molten Veins skips the wait and drops ingots straight into your inventory when you mine iron, gold, copper, or ancient debris.
But that's not all, hold your vein mine key and break one ore block to shatter the entire connected vein. Up to 256 blocks at once, all auto-smelted if applicable.
✨ Features
- Auto-Smelt: Mine ore, get ingots instantly (iron, gold, copper, ancient debris, clay)
- Vein Mining: Break entire ore veins with one block (works with ALL ores + hay bales + clay + obsidian!)
- Silk Touch Support: Silk Touch bypasses auto-smelt and drops ore blocks as expected
- Fortune Support: Auto-smelting respects fortune enchantment for bonus drops
- XP Bonus: Random 1-4x XP multiplier to compensate for skipped furnace XP
- Magnet Mode: Drops loot directly to your inventory
- Custom Config UI: Press Z for a fully custom-drawn settings screen with orange-themed design, toggle switches, item icons, and smooth animations
- Per-Block Toggles: Enable/disable each block type individually
- Rebindable Keys: Change hotkeys in Minecraft's controls menu
