About this Mod

Furnace Mk2 Banner

Welcome to Furnace Mk2

This mod is a *fairly* simple extension of the vanilla furnace. The primary intention is to provide a logical step between vanilla furnaces and whatever tech mod's high tiered electric mega-smelter. Sprinkle in some thoughtful improvements and this furnace can be a staple of anyone's base.

The mod intends to stay within a defined design scope and prioritizes quality over quantity. Functions and features should be fairly self explanatory through the use of tooltips. Features include increasing the speed, fuel efficiency, and experience output of the furnace, waste-free fuel management, and an item to manage the experience produced (and player's experience).

Furnace Overview

Furnace Overview Diagram

It may seem like there is a lot going on in the inventory, but it is designed to guide you through using it; empty slots indicate what they are, and areas of interest have tooltips that offer some added information. JEI/REI integration is included out of the box and uses the supplied vanilla furnace and fuel entries.

Attuned Crystal

While there is built-in experience storage implemented in the Furnace Mk2, placing an Attuned Crystal in the bottom-right slot will ensure that the crystal's capacity is continuously topped up (and it's quite a bit more than the furnace itself).

Clicking the crystal removes experience from itself to give to the player, and shift-clicking transfers the player's experience to the crystal. The crystal holds 10,000 experience which from 0 is just over 63 levels.

It also makes a sound with a pitch that's influenced by the capacity which is pretty neat.

Notes

The mod is currently in beta, let me know of any bugs or issues that occur and ensure that you're backing up/saving worlds before making any changes to the mods you use!

FurnaceMk2 server crashes on startup – what to do?

FurnaceMk2 officially supports fabric, forge, neoforge for Minecraft 1.21.1, 1.20.1, 1.19.2. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with FurnaceMk2 – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if FurnaceMk2 consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
