About this Mod

Custom Fuel

This mod lets you configure which items can be used as furnace fuel.

The settings are stored in custom_fuel.json in the config folder.

Config file format

A valid config file consists of two optional entries on the top level -
include and exclude.

  • include is a map where the keys are IDs for the items and/or item tags to
    be added to the list of fuel items, and their values are how long they last
    (in ticks, as an integer).
    • If a value is zero or negative, the item can be placed into the fuel slot,
      but will not burn. This behaviour relies on vanilla code, and may change at
      any point in the future.
  • exclude is an array of IDs for the item tags to no longer be usable as
    fuel items.

The mod applies the inclusions, then the exclusions, on top of the vanilla
fuel list (i.e. vanilla fuel items are kept intact unless you manually exclude
them).

A current limitation of this mod is that exclusions must be tags. To exclude
individual items, you have to make a datapack with your own custom tag that
contains all the individual items you want to exclude, and exclude that tag.

Example configuration

{
	"include": {
		"#c:netherracks": 3200,
		"#minecraft:beds": 300,
		"#minecraft:flowers": 50,
		"minecraft:redstone_block": 16000
	},
	"exclude": [
		"#minecraft:banners"
	]
}

Frequently Asked Questions

Custom Fuel server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.11). You can switch loaders with one click in the panel.

Custom Fuel officially supports fabric, quilt for Minecraft 1.21.11, 1.21.10, 1.21.9. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Custom Fuel – how to optimize performance?

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