KeepSmelting
KeepSmelting — a Minecraft Forge mod that makes furnaces continue smelting while you're offline.
Instead of halting progress when you exit the game or unload a chunk, KeepSmelting tracks real‑world time and catches up all missed smelting in batches when you log back in.
Features
- ⏰ Real‑time & Game‑time modes — survives chunk unloading, game exit, and menu pause
- 🔥 Vanilla furnaces — furnace, smoker, blast furnace
- ⚙️ Iron Furnaces — full support for all 13 tiers and 3 modes (Furnace, Factory, Generator) with every augment slot
- 📦 Hopper pipeline simulation — auto‑pull inputs/fuel from adjacent containers, push outputs through full hopper chains
- 🛠️ API for modders — add KeepSmelting support to your custom furnace with one registration call
- 🌍 English & Русский — fully localized into both languages
