Satisfactory: Installing Mods with Satisfactory Mod Manager

While Satisfactory 1.0 does not officially support mods, the community has created Satisfactory Mod Manager (SMM) - a powerful tool that allows you to easily install and manage mods on both your computer and dedicated servers. This guide covers everything from basic installation to troubleshooting common mod conflicts.

⚠️ Important Warning: Installing mods increases the likelihood of crashes, performance issues, and save file corruption. Always backup your save files before modding, especially on dedicated servers where multiple players are affected.

1. Client vs. Server Mods

Understand the difference: Client-side mods (visuals, UI changes) only need to be installed by each player. Server-side mods (new buildings, gameplay changes) must be installed on the server, and all players must have the same mods installed to connect.

2. SML Requirement

Most mods require Satisfactory Mod Loader (SML) to function. SMM automatically handles SML installation and updates, ensuring your mods can load correctly.

3. Version Compatibility

Mods are frequently broken by game updates. Always check if a mod has been updated for your current Satisfactory version before installing, especially after major patches like 1.0.

Installing Satisfactory Mod Manager

Step 1: Download and Install SMM

  1. Visit the Satisfactory Mod Manager GitHub releases page
  2. Download the latest version for your operating system (Windows or Linux)
  3. Run the installer and follow the on-screen prompts
  4. Launch SMM once installation is complete

Step 2: Connect to Your Server

  1. In SMM, click on Manage Servers tab in the left sidebar
  2. Click Add Server button
  3. Enter your server details:
    • Name: A recognizable name for your server
    • IP Address: Your server's IP address (e.g., 123.45.67.89)
    • Port: Typically 21 for SSH/SFTP connections
    • Username: Your server's FTP username
    • Password: Your server's FTP password
    • Connection Path: Enter the server path: /steamcmd/satisfactory/
  4. Click Test Connection to verify SMM can access your server

Step 3: Install Mods on the Server

  1. Once connected, you'll see your server listed in the Manage Servers section
  2. Click on your server to expand options
  3. Click the dropdown menu that shows your game version
  4. Select Early Access (Remote 1) for dedicated server mod installation
  5. Browse the available mod list or click Add Mod to upload a mod file
  6. Find and select the .smod file for the mod you want to install
  7. Wait for SMM to upload and install the mod on your server
  8. Repeat for additional mods you want to install

📦 Recommended Practice: Install mods one at a time and test your server between each installation. This makes it much easier to identify which specific mod is causing issues if problems arise.

Step 4: Install Mods on Your Computer

  1. In SMM, switch back to Early Access (Steam) or Epic Games tab in the left sidebar
  2. Browse the same mods you installed on the server
  3. Click Install for each mod on your local game
  4. Wait for installation to complete

All players connecting to your modded server must have the exact same mods installed on their local game! If a player tries to join without matching mods, they will be unable to connect.

Understanding Mod Types

Client-Side Mods

  • Visual Enhancements: Texture packs, UI improvements, lighting changes
  • Quality of Life: Better sounds, music, or visual effects
  • Interface Tweaks: Inventory management, HUD improvements, hotkey changes

Server-Side Mods

  • New Buildings: Additional machines, production lines, or structures
  • Gameplay Changes: New resources, recipe modifications, game mechanic changes
  • Performance Mods: Optimizations, alternative rendering, memory management
  • Must Be Synced: All players need identical mods to connect

Troubleshooting Mod Issues

Common Problems

  • Server Won't Start: A mod may be incompatible with the current game version or missing SML
  • Players Can't Connect: Mod version mismatch between server and clients
  • Save Corruption: Corrupted mod data causing game crashes
  • Performance Drops: Resource-heavy mods reducing FPS
  • Missing Dependencies: A mod requires another mod that isn't installed

Solutions

  1. Check Mod Versions: Ensure all mods are updated for your Satisfactory version
  2. Verify SML Installation: SMM should automatically install SML, but verify it's present in /FactoryGame/Binaries/Win64/
  3. Remove Conflicting Mods: Disable mods one by one to identify the culprit
  4. Read Mod Documentation: Check if the mod author has provided troubleshooting steps
  5. Test Vanilla: Try running the server without mods to verify it works

Recovering from Mod-Related Issues

  • Save Restoration: If a mod corrupted your save, restore from a backup
  • Mod Cleanup: Remove the Mods folder content to reset to vanilla
  • Blueprints Affected: Some modded buildings may disappear if the mod is removed - plan accordingly
  • SMM Reinstall: Uninstall and reinstall SMM if it becomes unresponsive

Best Practices

Server Management

  • Backup Before Modding: Always create a save backup before adding new mods
  • Test in Singleplayer: Try mods in singleplayer before installing on server
  • Document Your Mods: Keep a list of which mods you use and their versions
  • Regular Updates: Keep mods updated to match game patches
  • Mod Conflicts: Research mod compatibility before installing multiple mods

Player Coordination

  • Share Mod List: Provide all players with the exact mods and versions required
  • SMM Download Links: Direct players to download mods from the same SMM versions
  • Version Matching: Ensure everyone updates mods simultaneously
  • Communication: Discuss mod updates in server chat or Discord before applying
