SmeltPlus
About
SmeltPlus adds an automatic ore-smelting system to Paper *.21.11. Players with smelter.auto can use /smelt toggle to enable or disable automatic smelting, which starts enabled by default. Mining iron, gold, copper, and ancient debris converts their furnace-smeltable drops into ingots or netherite scraps while preserving normal quantities and drops. Players with smelt.inv can smelt every matching ore in their inventory with /smelt inv, and staff with smelt.admin can reload settings with /smelt reload.
