You’ve finally decided to do it. After three hundred hours of vanilla gameplay, the urge to give Astarion a ridiculous hat or make your Druid look like a literal god became too strong. You downloaded some files from Nexus, but now you’re staring at a folder of .pak files and feeling a bit overwhelmed. This is where the Baldur’s Gate 3 Mod Manager (BG3MM) comes in, or more specifically, LaughingLeader’s version, which is basically the gold standard for anyone who doesn't want to spend six hours troubleshooting a crash-to-desktop.
The game is massive. Larian built a masterpiece, but they also built a delicate house of cards when it comes to the underlying code. If you just drop files into a folder and hope for the best, you’re going to have a bad time.
Why Everyone Still Uses the Community Baldur's Gate 3 Mod Manager
Even though Larian eventually added official mod support in Patch 7, the community-made Baldur's Gate 3 Mod Manager hasn't gone anywhere. Why? Because the official toolkit is a bit of a walled garden. It’s great for the casual stuff, sure. But if you want the "script extender" stuff—the mods that actually change how the game’s brain works—you still need the community tool. It’s the difference between painting your car a new color and installing a nitro boost.
Most people don't realize that the "Official" support and the BG3MM can actually live together, but they can also fight like siblings in a small car. The community manager gives you a level of granular control over load orders that the in-game menu just can't match.
The load order is everything. It's the sequence in which the game reads your mods. If the game tries to load a mod that changes "Elven Hair" before it loads the mod that "Fixes Elven Textures," everything breaks. Your character might end up bald, or worse, the game just won't start. BG3MM lets you drag and drop these priorities in real-time. It’s visual. It’s tactile. Honestly, it’s just safer.
The Script Extender: The Invisible Hero
You cannot talk about the Baldur's Gate 3 Mod Manager without talking about Norbyte’s Script Extender. If the mod manager is the garage, the Script Extender is the specialized engine tool.
A lot of the coolest mods—things like "Party Limit Begone" or complex new spells—require the Script Extender to function. It allows mods to run code that the game wasn't originally designed to handle. Within the BG3MM interface, you can actually install this with a single click under the "Tools" menu. It’s a lifesaver. Without it, half the stuff on Nexus Mods is just dead weight.
Setting Everything Up Without Crying
First, grab the manager from GitHub. Don't go to some weird third-party mirror site. Just go to LaughingLeader's repository. Once you have it, you need to point it to your game’s "Data" folder. If you’re on Steam, it’s usually under steamapps/common/Baldurs Gate 3/Data.
Once the manager knows where the game is, it’ll show you two columns.
On the right, you have your "Inactive" mods. These are files you’ve downloaded but haven't "turned on" yet. On the left, you have your "Active" load order. This is the stuff that will actually show up when you hit "Play."
Here is a mistake almost everyone makes: they forget to export.
You can move mods to the left all day, but until you hit that little "Export Order to Game" icon (it looks like a blue floppy disk or a tiny page with an arrow), the game has no idea what you’ve done. You’re just moving icons around in a window. You have to write that "settings.lsx" file so the game knows what to do when it boots up.
Understanding the "Overrides" Section
Down at the bottom of the manager, you’ll see a section called "Overrides." These aren't like normal mods. You don't drag them to the left. They just... exist.

These are usually things like the "Mod Fixer" or UI skins. They sit there in a permanent state of "on." If you see a mod highlighted in a weird bronze or brown color at the bottom, don't panic. It's supposed to be there. Just make sure you aren't running three different UI overrides at once, or your HUD will look like a Picasso painting.
Dealing with the Patch 7 Conflict
When Larian released the official modding tools, it changed the file structure of how mods are stored. This caused a massive headache.
Essentially, the game now looks in two places for mods: the local AppData folder (where BG3MM puts things) and the internal game folders (where the official browser puts things).
If you’re using the Baldur's Gate 3 Mod Manager, you might notice that some mods you downloaded in-game are appearing in the list. This is fine. But if you try to manage an "official" mod using the "unofficial" manager, things can get weird. My advice? Pick a lane. If a mod is available through the official Larian portal, use that. If it's a "heavy" mod from Nexus that requires the Script Extender, use BG3MM.
Just keep an eye on your modsettings.lsx file. Sometimes the game likes to reset this file to "Vanilla" if it thinks something is wrong, wiping out your custom load order. If your mods suddenly stop working after a game update, that's almost always the culprit. Open BG3MM, re-drag your mods to the left, and hit export again.

The Golden Rule of Modding BG3
Back up your saves. Seriously.
Modding is essentially a polite way of breaking a game until it does what you want. Sometimes, it breaks for real. If you install a mod that adds a new race, play for fifty hours, and then that mod gets deleted or corrupted, your save file might be gone forever. The game won't know how to render your character, so it'll just crash.
Keep a "clean" save from before you started modding. It's your insurance policy.
Troubleshooting the "Everything is Broken" Phase
So you launched the game and you're getting a "Data Mismatch" warning. Or maybe you're stuck at a loading screen that says 100% but never moves.
First, check your "ImprovedUI." This is a foundational mod that almost every other mod relies on. If it's out of date, the whole game falls apart.
Second, check for "loose files." Some older mods don't come in .pak format. They come as folders like Public or Generated. These go directly into your Data folder. The Baldur's Gate 3 Mod Manager won't always see these, so you have to track them manually. If you have an old "basket full of outfits" mod that isn't working, check if it's a loose file.
Third, look at the "Fixer." For a long time, we needed a "Mod Fixer" to make anything work. Larian eventually integrated most of those fixes into the game engine. Sometimes, having the old Mod Fixer installed can actually cause more problems than it solves now. Try removing it if you're getting weird story-blocker bugs where you can't talk to NPCs.
Actionable Steps for a Stable Game
If you want to get your game running with mods today, follow this specific flow. Don't skip steps.
- Clean the Slate: If you’ve been messing with files manually, delete your
Modsfolder in%LocalAppData%\Larian Studios\Baldur's Gate 3\and let the game regenerate it. - Install the Manager: Download the latest release of LaughingLeader’s BG3MM.
- The Essentials: Download and install Script Extender (via the tool menu) and ImprovedUI. These are the bedrock.
- The Load Order: Place your "Core" mods (like ImprovedUI) at the very top of the active list. New items, classes, and spells usually go in the middle. Large overhauls or "cheat" menus often go toward the bottom.
- Save and Export: Click 'File' > 'Save Order', then click the 'Export' icon.
- The Binary Search: If the game crashes, disable half your mods. If it works, the problem is in the other half. Keep dividing until you find the one file causing the conflict. It’s tedious, but it’s the only way to be sure.
Modding Baldur’s Gate 3 is a journey. You’ll probably break the game at least once. But once you see your custom-clothed Tav standing in a campsite with 12 party members and a pet owlbear that breathes fire, you’ll realize the twenty minutes of fiddling with the Baldur's Gate 3 Mod Manager was worth it. Stay patient, read the mod descriptions on Nexus thoroughly, and always, always export your load order before hitting play.
