Fallout Modding PC

A Beginners Guide To Modding Fallout 4 In 2020

Spread the Word!

Even though I semi-retired from modding my games I still get plenty of questions about modding certain games. Lately, all of the questions that I’ve received has been on how to properly mod Fallout 4 in 2020.

I forgot to mention that you MUST at least run vanilla Fallout 4 one time before attempting any of this. Once you run the game once it’ll create the necessary files for you to edit when you’re ready to get to those INI files.

Okay, let’s get this out of the way. If you want to start modding Fallout 4 the very first thing you should do is download the Fallout 4 Script Extender (also known as f4se). F4se is a MUST HAVE plugin for Fallout 4 and most mods won’t even work without. It’s basically another launcher for your game (and will be the launcher that you click on every time you want to play), but it actually does more than that.

Installing f4se is quite easy. All you’ve got to do download it from here , extract it with a program (either Winrar or 7zip) and install it into your Fallout 4 main directory. Watch the short video below if you’re confused by what I wrote.

After you install f4se you’ll want to use a mod manager. I don’t recommend installing mods manually if you’re new to this. If you’re a pro what are you doing reading this :)? I There are plenty of mod managers out there to choose from, but the one I’ll be recommending is the Nexus Mod Manager. The official mod manager is no longer supported by Nexus Mods, but there is a fan version of it that actually works better than the original one did. You can find that by clicking here.

You’re probably thinking that you’re good to go from here and normally you would be if you were modding a game like Skyrim or any of the older Fallout games. Fallout 4 can be a pain in the ass to mod. Before you get to choose the mods that you want in your game you’ll need to write some lines in the Fallout Custom INI that’s located in your documents folder. It’ll read like this – This PC – Documents – My Games – Fallout 4. Once you’re in your Fallout 4 folder you’ll want to navigate down to the Fallout 4 Custom INI and write these lines in it. If there’s no [Archive] line add that too and write what’s below under it just the way you see it below.

bInvalidateOlderFiles=1
sResourceDataDirsFinal=

If for some reason this does not activate mods in your game add this line

sResourceDataDirsFinal=STRINGS, TEXTURES, MUSIC, SOUND, INTERFACE, MESHES, PROGRAMS, MATERIALS, LODSETTINGS, VIS, MISC, SCRIPTS, SHADERSFX\

This fix is outdated, but it does work for some people and I wanted to be thorough so…

There’s a short video below showing you where to find your Custom INI folder.

Now, it’s finally time for you to decide on what mods you to download to your game.

Here are some mods that I highly recommend that you add to your game.

Unofficial Fallout 4 Patch

This is one of those must-have mods. Even if you choose not to grab anything else on this list I highly recommend that you download this one. Why? Because it fixes thousands of bugs that range from small to game-breaking that Bethesda never bothered fixing.

Def_UI

Def_UI not only overhauls your inventory screen it also overhauls your hud. It’s one of those quality of life mods that doesn’t seem like much but adds a lot to the game. If you do decide to get this mod I recommend you use it with Valdacil’s Item Sorting for the best user experience. You’re getting two mods in one with Def_UI since it comes bundled (optionally) with Def_Hud and it’s very customizable. I can’t play Fallout 4 without these mods.

Full Dialogue Interface

One thing that always bothered me about my spoken protagonist was the fact that I never knew what line they would speak next. This mod changes that by allowing us to see what the next line of dialogue will be during conversations. It’s a must-have mod in my opinion.

There are other mods I could recommend, but instead of doing that, I’ll just leave a link to my Fallout 4 modding series that I wrote. I have multiple articles that covered all kinds of different mods in Fallout 4 that I think you would enjoy reading. If you click here you’ll be taken to my Fallout 4 modding archives. Some of them are pretty old and probably don’t have screenshots attached to them anymore, but I’m working on updating them. The links all stick work though and I think it’ll help you get to know the modding scene in Fallout 4.

What if you want to find your own mods and not the ones I’ve previously written about? Go to Nexusmods.com/fallout4 and you’ll be treated to thousands of Fallout 4 mods to browse through. Before you can download any mods you must create an account. It’s completely free with the option to pay to support the site.

And that’s it! You’re ready to start your Fallout 4 modding adventure! If you have any questions feel free to ask them here, over on Twitter, Facebook, or shoot me an email.
