RUST Quick Smelt Plugin (How to Install, Configure & Use)

What is the Quick Smelt plugin?

Quick Smelt (QS) is a RUST plugin designed to modify the smelting and output speed multipliers on a RUST server, allowing players to smelt various ores much faster than the default rates. Patched and supported by misticos, QS is a free-to-use plugin available to download on uMod. It is a favorite amongst the RUST modded community for its utility, particularly on multiplier servers.

Note: This mod will require the server status to be designated as Modded in the server listing. For more information on this, check out the Developers Guide on plugin use for RUST servers.

Potential reasons to use the Quick Smelt plugin

Quick Smelt is especially important on servers that have advanced gather rates. For context, imagine you’re on a 5x resources server, but the owner has elected not to include Quick Smelt in the server format. You might have 200,000 sulfur ore, but it will take you until you wipe to smelt it all. QS is the answer to this problem. Even if you don’t have advanced gather rates, this plugin is a quality-of-life enhancement that reduces the overall grind time in-game.

Installing the Quick Smelt plugin

As with all uMod plugins, the server you intend to install them on requires uMod (Oxide) to be installed to facilitate their function. For a step-by-step perspective on how to install this plugin, please reference the following list:

  1. First, you must have uMod/Oxide installed on your server. Use our Installing uMod (Oxide) on Your RUST server guide if you need help; otherwise, if you use a third-party hosting, their user interface will have instructions on how to get started. It may be tooled explicitly to their platform, so reach out to your host for details.
  2. Acquire the latest version of the plugin from uMod’s Quick Smelt page, or download the CS file directly.
  3. Locate the downloaded QuickSmelt.cs file and install the plugin on your RUST server, or follow your host-specific instructions.
  4. Once you’ve installed Quick Smelt in the plugins folder, and if the server is actively running, uMod will immediately create an alternate QuickSmelt.json file in your config folder. You will make all configuration changes to the .json file in the config folder.


The Quick Smelt plugin has a single permission required for its use unless administrators wish to limit it to only certain groups. The single permission is as follows:

quicksmelt.useGrants group permission to use all quick smelt functions

Additional dependencies

Like many other UMOD plugins, QS may work as a standalone mod or in conjunction with other select mods. A full list of such mods includes:

Activation steps

Once installed and permitted to use the mod, the server will allow anyone granted permission to use the configured functions.

Recommended plugin configurations

By default, the configuration of the QuickSmelt.json file should be adequate for most server owners’ purposes. To better understand potential option changes, this guide will go through the configuration file line by line as it pertains to the most commonly changed settings.

This is an example configuration file for Quick Smelt – It has been altered slightly to better explain the setting change impact – DO NOT copy and paste this example into your configuration.

“Global” within the context of this demonstration implies that all cooking devices will use these settings. You may replace furnace.shortname with specific entity types to include or exclude them.

""Use Permission"": true, - determinate whether permissions should be used
""Speed Multipliers"": { 
"global": 1.0, - convar for furnace tick rate
"furnace.shortname": 1.0
""Fuel Usage Speed Multipliers"": {
"global": 1.0, - convar for furnace fuel usage rate
"furnace.shortname": 1.0
"Fuel Usage Multipliers": {
"global": 1, - convar for furnace fuel cost per tick
"furnace.shortname": 1
""Output Multipliers"": {
"global": {
"global": 1.0 - convar for furnace output multiplier
"furnace.shortname": {
"item.shortname": 1.0
""Whitelist"": {
"global": [
"Item.shortname" - allows (if programmed) for meat / ore to be cookable across non-default platforms
"furnace.shortname": [
""Blacklist"": {
"global": [
""Item.shortname" " - allows (if programmed) for meat / ore to not be cookable across default platforms
"furnace.shortname": [
""Smelting Frequencies (Smelt items every N smelting ticks)"": {
"global": 1,
"furnace.shortname": 1
""Debug"": false

How to update the Quick Smelt plugin

Updating the RUST Quick Smelt plugin is simple and quick.

  1. Visit the uMod Quick Smelt plugin page
  2. Download the latest version of the Quick Smelt plugin
  3. Overwrite the existing QuickSmelt.cs file in your Oxide plugins folder.

It is best practice not to uninstall the mod, as you do not need to alter the JSON file. It will remain with your existing settings (unless the developer otherwise suggests a complete reinstall).

How to remove the Quick Smelt plugin

As the Quick Smelt plugin does impact the player experience and game features, removing the plugin will take a few extra steps.

  1. Prepare and properly shut down the RUST server
  2. Open the Oxide plugins folder in your server directory
  3. Locate and delete the QuickSmelt.cs file
  4. Open the Oxide config folder in your server directory
  5. Locate and delete the QuickSmelt.json configuration file
  6. Restart the RUST server

Suppose you want to disable the Quick Smelt plugin for a short period. You can use the oxide.unload QuickSmelt command, which you may also run in the F1 console, RCON, or Web Console.
