Want to play Terraria with your friends using custom mods? That’s where tModLoader comes in! It lets you install modpacks, which are groups of mods bundled together. But how do you share those awesome modpacks with your squad?
Don’t worry. It’s easier than it sounds! In this guide, we’ll take you step-by-step through the process of sharing your favorite modpacks with your friends using tModLoader.
What is tModLoader?
tModLoader is a tool that makes it easy to play Terraria with mods. It supports both single-player and multiplayer. Think of it like a friendly mod manager that plugs right into Terraria.
Rather than installing mods one by one, you can use modpacks. These are pre-made collections of mods that can be shared with others.
Step 1: Create Your Modpack
The first thing you need is a modpack to share! Here’s how to create one:
- Start tModLoader.
- From the main menu, click on Mods.
- Install and enable all the mods you want.
- In the Mods menu, click on the gear icon at the top right.
- Choose Save Modpack.
- Give your modpack a name and click Save.
Boom! You’ve now created a modpack. It’s saved under a folder we’ll use next.
Step 2: Find the Modpack Folder
To share the modpack, you need to find where it’s saved on your computer.
Follow these steps:
- Open your File Explorer.
- Go to this location:
C:\Users\YourName\Documents\My Games\Terraria\tModLoader\ModPacks - You’ll see a .json file or a folder with the name of the modpack you just saved.

This is the file you’ll need to send to your friends!
Step 3: Share the Modpack File
Now it’s time for the fun part – sending it to your buddies!
You can use any of these easy methods:
- Email: Attach the modpack file and send it.
- Google Drive: Upload the file and share the link.
- Discord: Drop the file in a group chat.
- USB Drive: Good for LAN parties!
Make sure your friends download the file and store it in their own ModPacks folder at:
C:\Users\YourName\Documents\My Games\Terraria\tModLoader\ModPacks
Step 4: Load the Modpack (Your Friends’ Side)
Now they need to load it in tModLoader. Here’s how:
- Open tModLoader.
- Go to Mods from the menu.
- Click the gear icon in the Mods menu.
- Select Open Modpacks or click Load Modpack.
- Pick the modpack you sent them and click Load.
Your friends will now automatically have the same mods enabled that you saved in the pack. No need to search and download each one manually!
Step 5: Sync Versions
Sometimes, people have different versions of mods. That can cause crashes or errors.
Make sure both you and your friends:
- Have the same version of tModLoader.
- Have the same versions of each mod.
If something’s off, head to the Mods menu and click Update All to get the latest versions.
It keeps everyone on the same page, and your game won’t throw tantrums.
Optional: Use the Workshop
Did you know you can use the Steam Workshop to share modpacks?
Here’s how:
- In tModLoader, go to the Mods menu.
- Click the gear icon and choose Publish Modpack.
- Fill in the details and hit Publish.
Now your modpack is public on the Workshop! Your friends can just find it by name and install with one click.

This method is super convenient and great for larger groups or public modpacks.
Bonus Tips!
Here are some extra tips to keep your Terraria adventure smooth and fun:
- Use a voice chat: Discord or Steam chat makes coordinating easier while playing.
- Test before sharing: Try your modpack in single player first. Make sure it loads properly.
- Make backups: Always save your worlds and characters just in case.
- Label your modpack: Give it a clear name like SkyFactoryV2 or MagicMayhem2024 so others know what it’s about.
- Include a mod list: A simple text file with the mod names can help others troubleshoot issues later.
Common Problems and Easy Fixes
Sometimes things go wrong. Here are quick fixes to some common problems:
- Game crashes on load: Likely due to mismatched mod versions. Try updating all mods.
- Mods keep disabling: Check that your friends have properly loaded the modpack and not just installed it.
- Missing mods: If a mod isn’t downloaded, your friend will need to manually get it from the Workshop or Mods browser.
Ready to Play Together?
Starting a multiplayer game is easy once everyone has the modpack installed.
- One person hosts the world using the Multiplayer > Host & Play option.
- Others join using Join via IP or from the Friends List if using Steam.
- Make sure mods are loaded before starting the world!
Now you’re all set to build, battle, and explore with your crew using your custom modpack! 🌟
