How It Works
In vanilla Rust, the Large Furnace and Oil Refinery can't be placed inside buildings — they require open sky above them. On Markiii-Rust, this restriction is completely removed. You can place any furnace type fully indoors, inside enclosed rooms, under ceilings, wherever you like.
This applies to all furnace types: the Small Furnace, Large Furnace, Oil Refinery, and Electric Furnace. Just craft or find one and place it inside your base like any other deployable. No commands needed — it just works.
Build a dedicated smelting room inside your base — stack your furnaces in a sealed room for a clean, organised setup. No more building awkward open-air furnace platforms on your roof.

No — it works automatically for all players. Just place a furnace where you want it. No commands, no special permissions, no VIP required.
No — furnaces work exactly the same as normal. The only change is that the placement restriction is removed, allowing them to be placed indoors. Smelting speed, fuel consumption, and output are all unchanged.
