How to Use Quick Smelt on a Rust Server

Rust·May 20, 2026·21 min read

Overview

Rust progression often slows down at the furnace. Ore, sulfur, and other materials need time to smelt before players can craft better tools, weapons, armor, and base upgrades. On a busy server, waiting around for furnaces can feel like a second job, minus the paycheck.

Quick Smelt is a uMod plugin that lets server owners control how fast smelting happens. It can also adjust fuel usage, output amounts, and behavior for specific smelting entities. You can make smelting instant, slightly faster than vanilla, or tuned separately for furnaces, large furnaces, and other supported entities.

This guide explains how to install Quick Smelt on a Rust server, grant its permission, edit the config file, and fix the most common setup problems.

Installing Quick Smelt

  • Open the Quick Smelt page on uMod and select Download.
  • Save the plugin file somewhere easy to find on your computer.
  • Open your server panel, then go to FTP or the file manager. Make sure you are working on the correct server profile before uploading anything.
  • Log in with your panel password, then open the `oxide` directory.
  • Go into the `plugins` folder and select Upload.
  • Drag the Quick Smelt plugin file into the upload area and wait until it reaches 100%.
  • Return to the main server panel and restart the server.

After the restart, join the server or check the console to confirm the plugin loaded correctly.

First Setup

Quick Smelt does not fully change smelting behavior just because the plugin file exists. Players need the correct permission, and most servers will also need config changes before the plugin behaves the way the owner wants.

The basic setup has two parts:

  • Grant `quicksmelt.use` to a player or group.
  • Edit `QuickSmelt.json` to control speed, fuel usage, and output.

Once both are done, furnaces should smelt according to your configured values.

Granting the Permission

Quick Smelt uses Oxide permissions. You can grant the permission to a single player, or to a group such as admin, default, VIP, or any custom group already configured on the server.

Grant a User Permission

  • Open the server panel and select Console.
  • In the command box, enter this command:

`oxide.grant user [player/SteamID] quicksmelt.use`

  • Replace `[player/SteamID]` with the player name or SteamID.
  • Select Send to run the command.

This must be repeated for each individual player that should use Quick Smelt.

Grant a Group Permission

  • Open Console from the server panel.
  • Enter this command:

`oxide.grant group [name] quicksmelt.use`

  • Replace `[name]` with the group ID, then select Send.

Granting the permission to a group is usually cleaner for public servers, since new members of that group inherit the permission automatically.

Configuring Quick Smelt

The config file controls how aggressive the smelting changes are. This is where you decide whether the server should use a mild boost, a fast-paced setup, or near-instant smelting.

  • Open FTP or the file manager from the server panel.
  • Go to the `oxide` directory, then open the `config` folder.
  • Find `QuickSmelt.json` and select Edit.
  • Adjust the `global` values if you want the same behavior across all supported smelting entities.
  • To customize a specific entity instead, edit the matching `furnace.shortname` section and change the values there.
  • Select Save, return to the main panel, and restart the server.

Restarting is important. Rust servers are not known for politely guessing what config you meant to load.

What to Change

The exact options can vary by plugin version, but Quick Smelt commonly uses multipliers for speed, fuel usage, and output. Higher speed values make items finish faster. Fuel settings control how quickly wood or other fuel is consumed. Output settings can increase or reduce the amount produced from each smelting cycle.

For most survival servers, avoid making everything instant unless that is the whole point of the server. A moderate global multiplier keeps crafting moving without deleting the resource economy. For high-rate, battlefield, or build-focused servers, stronger multipliers can make sense.

A practical starting point is to change only the global values first, restart, test with a furnace, and then tune specific furnace entries afterward. This makes it easier to identify which setting caused a problem if the config breaks.

Common Issues

The Plugin Does Not Work

First, confirm that the plugin file was uploaded to the correct server profile and placed inside `oxide/plugins`. If it was uploaded somewhere else, the server will ignore it.

Next, restart the server after uploading the file. A reload command may work in some cases, but a full restart is the simplest way to confirm the plugin starts cleanly.

If the plugin still does not load, check the console for Oxide errors and confirm the file was downloaded from the current Quick Smelt page on uMod.

Smelting Still Feels Vanilla

This usually means the player or group does not have `quicksmelt.use`. Grant the permission again, then test with the same account. If you granted it to a group, confirm the player is actually in that group.

Config Changes Do Not Apply

After editing `QuickSmelt.json`, select Save and restart the server. If the server falls back to defaults, the config may contain an invalid item name, number, comma, bracket, or quote. The console will usually report that the config could not be loaded and that defaults were used instead.

When that happens, reopen the file, fix the formatting, save it, and restart again.
