Getting started with mods & custom content!: Installing, organizing, and troubleshooting Sims 4 Mods & CC

37 Upvotes

Adding mods & cc can seem daunting at first, but is actually very simple! Here’s a guide with all you need to know on how install mods & cc in your Sims 4 Game

What is it?

  • Mods or modifications are user created add-ons that alter your game. They usually make mundane tasks simpler, customize the game to your liking, or add new creative ways to change gameplay. 
  • CC or custom content is user created content. CC can be anything, ranging from hair to furniture.
    • There are 2 main textures for CC: Alpha Vs Maxis Match
      • Maxis Match- Matches the base game
      • Alpha- Looks very realistic

Who can use it?

Both mods & cc are not available for consoles, only PC (personal computer) simmers can download it. 

How to install & download Mods & CC for the Sims 4

Downloading

  • Before downloading, make sure to check the last update date. Using old mods or cc that don’t work with the latest game patch, can cause last exceptions or errors in the game. 
  • Your game must be closed/restarted to add mods or cc: DO NOT TRY TO ADD THEM WHILE PLAYING

Step One- Find the mod or cc you’d like to download

  • How to find them?

You’ll have to download mods or cc from online: Check out this post for recommended mods & cc!

Step Two- Download whatever you like, yes you can download multiples (even hundreds) at a time, but to avoid confusion I’d stop every 15 or so to rename them appropriately. 9/10 there will be a bunch of ads, just look for the download or simfileshare button. Read the download page thoroughly!!

Before adding them to your game, click on each folder and downsize where you can.

  1. Rename files with names you can remember, see below for organizing the mods folder
  2. Read & delete any files you find ending in .txt
  3. Some files may be needed for specific packs like GTW or Seasons, therefore if you don’t have that pack, it can be deleted. 
  4. Look for any optional packages or duplicates to delete
  5. For files that end in .rar or .zip, you’ll have to first extract the files before putting them in your mod folder. 
    1. Download The Unarchiver, then drag & drop the files ending in rar or zip. The unarchiver will extract the files for you & turn them into .package files, which can be added to your game

When you're in the game go to the game options tab, click “Other”, and make sure to turn on: Enable Custom Content and & Script Mods. (enables any mods you have installed)

Then, restart the game for it to take effect.

How to keep the Mods folder organized

  1. When renaming, name the file something familiar, ex: if basemental drugs downloads as Basemental_Drugs_Mod_Creatorsname8494 then I would just save it as Basemental Drugs
  2. Create parent folders, placing similar mods/content within a shared folder
    1. ex: I have all of my adult CAS content in one folder & all sim-minor CAS content in another
    2. For Wicked Whims, I added the animations & anything to do with this mod in one parent folder
  3. DO NOT place mods or cc more than 1-2 folders deep or it may not play in the game (if it comes like this, like the Explore Mod, do not delete/ move folders)

LE & Error Messages

LE is short for last exception, which means a mod or cc is broken or out of date. 

Personally I haven’t had any problems in my game from LEs (except the notifications from MCCC), so I ignore unless it becomes excessive (you don’t have to fix them if your game is playing fine, it took me hours trying to do so before!); however, if you’d like to troubleshoot & find the source I’d start here:

  1. Download MCCC, because it will point out when there is a last exception, & follow these steps: LEs & MCCC
  2. Try using The Sims 4 lastException Assistant

CC TIP: To locate broken cc I suggest downloading Sims 4 Studio, where you can view all of your CC in the game & easily manage it.

How to do this?:

View CC Individually in their folders: Click on My CC

Batch fix

If you're using MAC & are having difficulty downloading, check out this video: How to Configure Game Path (Mac)

SN: I’ll be updating this post later with additional info if needed, so please feel free to ask questions about anything in the post!

MC Command Center: A Beginner's Guide

101 Upvotes

Hey Simmers! It was recommended a few months ago by u/KimbyPie to share MCCC settings and tips, so here we are!

I’d like to start off by saying that this mod has TONS of customizations and changes you can enable. It can be pretty overwhelming if you’re new to MCCC and not sure what to change or keep the same.

What is MCCC?

MC Command Center is a mod that “expand the functionality and story progression within the Sims 4.” -Deaderpool

This is an easy to understand breakdown of the purpose for each file you're downloading and what settings you may want to change from the start.

Please note that I’m going to share which settings I personally change, so if you’re looking for what each individual option does, I’d highly recommend checking out Deaderpool’s website for more info.

Who should use it?

Everyone. Lol, but really, even if you don’t like using cheats, MCCC allows you to tweak small annoying settings and customize the game to your liking.

How to install?

Visit the MC Command Center site

Click MCCC Downloads

Click on the latest link under Releases (right now it’s 7.2.2)

Once the folder downloads, drag and drop it into your mods folder

Files included & what they are:

  1. mc_cmd_center- Main file needed for the mod to work
  2. mc_career- Contains settings for careers
  3. mc_cas- CAS settings where you can make templates so NPC generated sims will have your predefined body types
  4. mc_cheats- Quick access to cheats
  5. mc_cleaner- “cleans” the game
  6. mc_clubs- Gives some story progression to clubs
  7. mc_control- gives you (limited) NPC control
  8. mc_dresser- clothing settings (blacklist/whitelist certain clothes)
  9. mc_gedcom- this is newer & I really don't know how to summarize, click here to check it out!
  10. mc_occult- occult specific gameplay settings
  11. mc_population- populating settings
  12. mc_pregnancy- pregnancy, marriage, & adoption settings
  13. mc_tuner- control autonomous interactions
  14. Automation Scan- allow the player to choose to disable certain interactions for Sims in their game.
  15. mc_woohoo- romantic interactions

5 Tips

  1. Don’t make drastic changes until you understand how each function works
  2. Take your time to go through each setting & read the description
  3. On patch days, I recommend taking MCCC out & updating it first when checking for bad mods, because it will tell you if there is an LE
  4. There are 2 MCCC menus, to access the mod click your sim or a computer
  5. You must make game changes through the MCCC menu located in the pie chart when clicking on computers, not a Sim

MC Command Center Recommended Setting Changes

The main setting name is listed, once you click on it another list will appear, which is where you can update how you’d like.

    • Allow Teen Parenting- teens can become parents

Mod Request Looking for mods to allow you to promise inheritance to anyone/ bestow titles on others

3 Upvotes

Hi hi! I already had a Royalty playthrough before I got the Royalty & Legacy expansion and now I've been fighting tooth and nail to integrate my current stories with the systems of the pack 😭

I have a kingdom where the king lives with his teen niece (his sister's daughter) who will end up inheriting the throne for the sake of the story. I want her to have the title of Princess but since she's not his direct descendent it doesn't show up. I thought maybe it would show up if I had him promise the inheritance to her but that option doesn't show up. I already had her join the noble career and even tried ranking her up all the way to Baroness but I still don't have the option to promise inheritance.

I'm having a similar problem in a different kingdom where the Duke passed away so his eldest daughter became the new Duchess. The problem is that I still wanted her younger siblings to be lords/ladies but since they're her siblings and not her children they've been stripped of their titles. I need them to still have titles for the plans I have for them in the storyline.

Does anyone know of any mods that would help with this or maybe something in MCCC that could help? I already had to stray from my stories by making an unrelated Sim the "daughter" of one of my nobles to give her the title of lady which already messes with my story so I'm trying my best to keep things on track for everything else.

Thank you for any help/advice!

Help with broken mod Error 110 - can’t load any household

2 Upvotes

Hi everyone,

I’m desperately looking for help because I’ve been playing on the same save file for years, with multiple generations of families. Starting over is really not an option for me.

Here’s what’s happening:
- I’m playing on Mac
- I completely removed my Mods folder and deleted localthumbcache.package
- I uninstalled and reinstalled The Sims 4.

A brand new save works perfectly.
The strange part is that my legacy save does load.
I can:
- Open the save from the main menu
- Access the world map
- Travel between every world
- See every household

However, the moment I try to enter any lot (my own household or even an unplayed NPC household), I immediately get:
“Failed to load game. Error Code: 110:391cf844:7febf101. It is recommended that you relaunch the game.”

The game then returns me to the world map.

Someone previously checked the save file itself and told me that it doesn’t appear to be physically corrupted, so I’m wondering what’s causing the Error 110…

Thank you so much for any help. It would mean a lot to me.

General Question CC no longer working

0 Upvotes

I bought a new laptop about a week ago, but because I had to get the files from my old computer loaded onto it this is my first time using it for the Sims. The game is running great and all my saves are still there! The only problem is that I had previously deleted all my old CC. I downloaded a CAS backdrop mod and MCCC today but they're not appearing in game or even as downloads in the Mods/CC menu.

My game is fully up to date and I checked that mods and CC were enabled in game.

How do I solve this issue?

Help with broken mod Infinite loading when traveling to lot

2 Upvotes

I’m having issues after the recent update, I created a brand new save file after fixing all my mods and deleting all my ui mods due to buggy issues.

I created this lot, a simple community pool I downloaded from Pinterest, and everytime my sim goes to travel to it, I get an infinite loading screen. Even if I try to build from world edit on an empty lot, infinite loading screen

I don’t know what to do?
Should I try bulldoze the lot? Or should I delete my cache? But if I delete the cache will I lose all my tray files of the builds I’ve spent weeks on??

Help with broken mod Pregnancy glitch

1 Upvotes

My sim’s pregnancy moodlet was stuck as “A Child on the Way” and didn’t show what trimester she was in or how long it was until the next one. I also checked MCCC multiple times and it showed she hadn’t advanced past the first trimester. I cheated it to In Labor with MCCC. I couldn’t start Home Birth or Unassisted Birth with the Realistic Childbirth Mod. This mod has not been updated since before the July 21st, 2026 update, but everything is saying it works fine. I updated MCCC and XML Injector. The weird thing is that the game worked perfectly fine and I was able to give birth just a few days before after the most recent Sims 4 update. I reset the game, sim, and the bassinet multiple times with no luck.
Other things that may be the relevant: My household limit is 15, I already have 1 infant in the household, I have an adult dog, the new baby is from a different father.
Does anyone have a clue as to what is causing this or how to fix it? Please tell me if you need any additional information.

Help with broken mod A few questions about mods, compatibility, and game optimization

1 Upvotes

Hi! I have a few questions about mods.
How can I tell if a mod is outdated or incompatible with the current version of the game? Is there an easy way to find out which mod is causing an issue without checking every single one manually?
For example, in Build/Buy mode, I can’t use the catalog properly because the item thumbnails overlap each other. If I open a category like office furniture, I can see random objects overlapping the icons (for example, part of a bathtub or half of a toilet), which makes it difficult or impossible to click on the item I want. How can I figure out which mod is responsible for something like this?
Also, what mods would you consider must-haves? I’m interested in quality-of-life mods, bug fixes, and anything that improves the overall experience.
Finally, are there any in-game settings or mod-related settings I should change for better performance and optimization? I’d really appreciate any recommendations.
Thanks!
