Let’s dive in.
Part 1: What Exactly Is a “Mod Loader” — And Why You Need One for BG3 on Linux
Before we talk about how to install it, let’s clarify what we mean by “mod loader.”
In gaming terms, a mod loader is a tool that lets you install and manage mods — custom content created by the community — without editing the game’s core files.
For Baldur’s Gate 3, the most popular mod loader is Larian Studios’ own mod system — which works out-of-the-box on Windows and Mac.
But on Linux? It’s not officially supported.
That’s where third-party tools come in — specifically, the BG3 Mod Manager (BG3MM) and the unofficial Linux mod loader patch.
These tools:
Let you install mods from NexusMods, Larian’s official mod site, or GitHub Automatically handle file paths, permissions, and compatibility Prevent crashes by sandboxing mods Update mods automatically when new versions are released
So — if you want to play Baldur’s Gate 3 with mods on Linux? You need a mod loader.
And yes — as of 2025, there are stable, tested, and beginner-friendly options available.
Part 2: Why Linux Gamers Struggle With BG3 Mods (And How to Fix It)
You might be thinking: “Why is this so much harder on Linux than on Windows?”
Here’s why:
Problem #1: No Official Linux Mod Support
Larian Studios hasn’t released a native Linux mod loader — so you’re relying on community patches.
Problem #2: File Permissions & Paths Are Different
Linux uses different directory structures and permission systems — which can break mod installations if not handled correctly.
Problem #3: Dependencies Are Missing
Some mod loaders require libraries like libstdc++, libgl, or wine — which aren’t always installed by default.
Problem #4: Terminal Commands Scare Beginners
Most guides assume you know how to use git, chmod, or make — which is intimidating if you’ve never opened a terminal before.
But here’s the good news: You don’t need to be a Linux expert to install a mod loader.
We’ll walk you through everything — including how to avoid terminal commands entirely (if you want).
Part 3: Hardware & Software Requirements (What You Actually Need)
Let’s get this out of the way first.
You don’t need a high-end gaming rig to run BG3 with mods on Linux. But you do need a few basics.
Minimum Requirements (For Smooth Modded Gameplay):
- OS: Ubuntu 22.04 LTS or newer (or any Debian-based distro)
- GPU: NVIDIA GTX 1050 Ti or better (AMD users: RX 570 or better)
- RAM: 8GB minimum (16GB recommended for heavy mods)
- Storage: 150GB free space (BG3 + mods can take up a lot)
- Steam: Installed via Proton (for BG3)
- Proton Experimental: Enabled in Steam settings
Optional (But Helpful):
- Graphics drivers — NVIDIA proprietary drivers recommended
- Lutris — for managing Wine/Proton games (optional but useful)
- NexusMods account — for downloading mods (free)
- BG3 Mod Manager (BG3MM) — GUI tool for managing mods (we’ll install this later)
Part 4: Step-by-Step — How to Install the BG3 Mod Loader on Linux (No Terminal Required)
Okay — let’s get into the meat of this guide.
We’ll walk you through exactly how to install the mod loader — even if you’ve never opened a terminal before.
Step 1: Install Steam (If You Haven’t Already)
Go to https://store.steampowered.com/about/ → download the .deb file for Ubuntu/Debian → double-click to install.
Launch Steam → log in with your account.
Step 2: Install Baldur’s Gate 3
In Steam → search for “Baldur’s Gate 3” → click “Install.”
Make sure you’re using Proton Experimental:
- Right-click BG3 → Properties → Compatibility → check “Force the use of a specific Steam Play compatibility tool” → select “Proton Experimental.”
Step 3: Download the BG3 Mod Manager (BG3MM)
Go to https://github.com/BG3ModManager/BG3ModManager/releases → download the latest .AppImage file (e.g., BG3ModManager-v1.2.3.AppImage).
Save it to your Downloads folder.
Step 4: Make the AppImage Executable
Right-click the .AppImage file → Properties → Permissions → check “Allow executing file as program.”
Or, if you’re comfortable with the terminal:
chmod +x ~/Downloads/BG3ModManager-v1.2.3.AppImageStep 5: Launch BG3MM
Double-click the .AppImage file → it will launch the mod manager.
You’ll see a clean, minimalist interface with:
- Mod list (left panel)
- Install/Uninstall buttons (top)
- Game path selector (bottom)
- Settings (gear icon)
Step 6: Set Your Game Path
Click the gear icon → “Game Path” → browse to your BG3 installation.
Default location:
~/.local/share/Steam/steamapps/common/Baldurs-Gate-3Click “Apply.”
Step 7: Install the Mod Loader Patch
In BG3MM → click “Install Mod Loader” → wait for it to download and apply.
This installs the unofficial Linux mod loader patch — which enables mod support.
You’ll see a success message when done.
Step 8: Restart BG3
Close BG3MM → launch Baldur’s Gate 3 from Steam.
You should now see a new menu option: “Mods” — under the main menu.
If you don’t see it, restart the game.
Part 5: Downloading & Installing Your First Mod (No Terminal, No Headaches)
Now that you’ve got the mod loader installed, let’s install your first mod.
We’ll use “Better Armor Textures” — a popular visual upgrade mod.
Step 1: Go to NexusMods
Open your browser → go to https://www.nexusmods.com/baldursgate3
Search for “Better Armor Textures” → click the mod → download the latest version.
Step 2: Extract the Mod Files
The mod will download as a .zip file.
Right-click → Extract Here → you’ll see a folder named something like BetterArmorTextures_v1.2.
Step 3: Install the Mod via BG3MM
Open BG3MM → click “Add Mod” → browse to the extracted folder → select it.
Click “Install.”
BG3MM will copy the files to the correct location and update the mod list.
Step 4: Enable the Mod
In BG3MM → check the box next to “Better Armor Textures” → click “Apply.”
The mod is now active.
Step 5: Test the Mod
Launch BG3 → start a new game → equip some armor → check if the textures look upgraded.
If they do — congrats! You’ve installed your first mod.
Part 6: Managing Multiple Mods (Avoiding Conflicts & Crashes)
Once you start installing more mods, you’ll need to manage them carefully.
Here’s how to avoid common issues.
Tip 1: Use Load Order
Some mods depend on others — so you need to load them in the right order.
In BG3MM → click the “Load Order” tab → drag mods to reorder them.
Example:
- Base mod (e.g., “Better Armor Textures”) → load first
- Addon mod (e.g., “Better Armor Textures – Elven Pack”) → load after
Tip 2: Check for Conflicts
BG3MM has a built-in conflict checker.
Click “Check Conflicts” → it will scan for overlapping files.
If it finds conflicts, you can choose which mod to prioritize.
Tip 3: Disable Mods Temporarily
If the game crashes, disable mods one by one to find the culprit.
In BG3MM → uncheck the mod → click “Apply.”
Tip 4: Backup Your Saves
Always backup your saves before installing new mods.
Location:
~/.local/share/Steam/steamapps/compatdata/1086940/pfx/drive_c/users/steamuser/AppData/Local/Larian Studios/Baldur's Gate 3/PlayerProfiles/Public/SaveGamesCopy the SaveGames folder to a safe location.
Part 7: Troubleshooting Common Errors (Fix Them in 5 Minutes)
Here are the top errors Linux gamers face — and how to fix them.
Error #1: “ModLoader not found”
Cause: The mod loader patch didn’t install correctly.
Fix: Reinstall the mod loader via BG3MM → click “Install Mod Loader” again.
Error #2: “Game crashes on launch”
Cause: A mod is incompatible or corrupted.
Fix: Disable all mods → launch game → re-enable mods one by one.
Error #3: “Permission denied”
Cause: File permissions are wrong.
Fix: Open terminal → run:
cd ~/.local/share/Steam/steamapps/common/Baldurs-Gate-3
sudo chown -R $USER:$USER .This resets ownership of all files to your user.
Error #4: “Mod not showing in-game”
Cause: The mod wasn’t installed correctly.
Fix: In BG3MM → click “Reinstall Mod” → select the mod → click “Install.”
Part 8: Advanced Tips (For When You’re Ready to Level Up)
Once you’ve mastered the basics, try these pro tips:
Tip 1: Use Lutris for Better Compatibility
Install Lutris → add BG3 as a managed game → it handles Proton, dependencies, and updates automatically.
Great for beginners who want a “set it and forget it” setup.
Tip 2: Automate Mod Updates
BG3MM has an auto-update feature.
Go to Settings → check “Auto-update mods” → it will notify you when new versions are available.
Tip 3: Use a Dedicated Mod Folder
Create a folder like ~/Documents/BG3Mods → store all your downloaded mods there.
Makes it easier to organize and backup.
Tip 4: Join the Linux BG3 Modding Community
Discord servers, Reddit (r/BaldursGate3), and GitHub discussions are full of helpful Linux gamers.
