UI Cheats Extension Sims 4: Updated Guide for v1.54 (2026 Full List)

UI Cheats Sims 4 is hands down the one mod I refuse to play without anymore. If you’ve ever fumbled trying to type modifyrelationship for the tenth time or rage-quit because you typo’d motherlode again, this mod basically saves your sanity. I’ve been running it across every save for years now, and the latest v1.54 update just made it even better.

In this guide I’m covering:

• What UI Cheats actually does and why it matters
• Step-by-step install (PC and Mac)
• Every single cheat the mod unlocks
• The brand new v1.54 features (Formative Moments, finally)
• My personal favorite tricks I use every session
• Common mistakes that break the mod
• Pro tips most guides skip

I’ve spent hundreds of hours testing this thing across legacy saves, fresh CAS files, and every expansion I own. If something doesn’t work or there’s a smarter way to use it, I’ve probably already messed it up at least once.

What Is UI Cheats Extension, Really?

UI Cheats Extension is a script mod made by weerbesu. The simple version: instead of opening the cheat console and typing commands, you just right-click stuff in the game’s interface and a menu pops up. Need to fill your Sim’s hunger? Click the bar. Want to slap 999,999 simoleons on the household? Click the money counter.

That’s it. That’s the whole pitch. But the reason it’s been one of the most downloaded Sims 4 mods for years is because it works on basically every panel in the game. Needs, skills, careers, relationships, traits, milestones, weather, seasons, lunar phases, eco footprint, vampire ranks, fame, you name it.

Here’s the thing. The vanilla cheat console is fine until it isn’t. Half the cheats need exact syntax, some need specific Sim IDs, and one wrong character means nothing happens. Once you start using UI Cheats, going back feels like trying to text on a flip phone.

Who made it and where to get it

The mod is made by weerbesu and distributed exclusively through their Patreon page. It’s totally free, no pledge required. You don’t need to subscribe, sign up, or hand over a credit card. Just scroll to the bottom of the post and grab the zip file.

A heads up though: do not download UI Cheats from random mod-hosting sites. There have been malware issues floating around the Sims modding community recently, and the only safe place is weerbesu’s official Patreon.

How to Install UI Cheats Sims 4 (Step-by-Step)

This is where most people mess up, so I’m going to be really specific. The mod uses two files and they both need to live in the right place.

Step 1: Download the Mod

1. Go to weerbesu’s Patreon page
2. Find the latest “UI Cheats Extension” post (currently v1.54)
3. Scroll past the patch notes to the bottom of the post
4. Click the blue download link for the zip file

You don’t need to be a paying patron. The download button sits right there on the public post.

Step 2: Extract the Files

Right-click the zip and hit Extract All on Windows, or just double-click on Mac. You should see two files inside:

• A .package file
• A .ts4script file

You need both of these. If you only copy one, the mod won’t work.

Step 3: Drop Them in Your Mods Folder

The default Mods folder lives at:

Documents > Electronic Arts > The Sims 4 > Mods

Drop both files directly into the Mods folder, or one subfolder deep at most. So either of these is fine:

• Mods/UI_Cheats_Extension.ts4script ✅
• Mods/UI Cheats/UI_Cheats_Extension.ts4script ✅

This one will break it:

• Mods/Script Mods/UI Cheats/UI_Cheats_Extension.ts4script ❌

The game can only read script mods that are one folder deep. I learned this the hard way after spending an hour wondering why the mod wasn’t loading.

Step 4: Enable Script Mods in Game

This step trips up so many new modders. Launch the game, then:

1. Go to Options
2. Click Game Options
3. Click Other
4. Check both boxes: “Enable Custom Content and Mods” AND “Script Mods Allowed”
5. Hit Apply Changes
6. Restart the game (yes, you have to restart for script mods to load)

That second checkbox is the one most people forget. If your money counter doesn’t react when you right-click it after install, this is almost always why.

Step 5: Confirm It’s Working

Load any save. Right-click the household money counter at the top of the screen. If a menu pops up letting you set funds, you’re good. If nothing happens, something’s wrong with the install.

You can also check your version by typing ui_cheats.mod_version in the cheat console (Ctrl + Shift + C).

The Latest UI Cheats Sims 4 Update (v1.54)

This is fresh. Version 1.54 dropped on April 20, 2026 and it’s built for game version 1.123.66.

What’s New in v1.54

The big addition is Formative Moments support inside the add trait menu. If you don’t know what those are, Formative Moments are basically backstory traits that get assigned based on how a Sim was raised in childhood. Stuff like “Action-Packed Childhood” or moments tied to specific life events.

Before this update, you couldn’t manually assign Formative Moments. They only triggered through actual gameplay or weird console commands. Now you can right-click the Traits panel, scroll through Formative Moments, and slap them on any Sim you want.

Why this matters

For me, the biggest deal here is fixing broken legacy saves. I had a Sim whose Formative Moment never registered because of some bug, and I had no way to add it back. Now I can. If you’re a story-driven player or a save file creator who shares Sims to the gallery, this is huge.

Recent version history worth knowing

The mod has been getting steady updates. Here’s what’s been added in the last few patches:

• v1.54 (current): Formative Moments support
• v1.53: Updated for game version 1.122.212, added Luck cheat to Simology panel
• v1.52: Royalty & Legacy patch support, Dynasty Prestige and Perks cheats
• v1.51: Mastery Perk cheat in Skills panel
• v1.50: Adventure Awaits patch support, Balance & Imbalance cheat

Weerbesu updates this thing within days of every major game patch. That consistency is half the reason it’s the gold standard.

My Best UI Cheats Sims 4 Picks (What I Actually Use)

Out of everything above, here are the seven I find myself using almost every session.

1. Fill all needs (one-click)

Right-clicking the needs panel icon to top off every motive at once is something I do probably 50 times per play session. Especially with toddlers.

2. Set household funds

I’m a builder more than a story player, so just slamming 9 million simoleons on a fresh save before I start building is my entire vibe.

3. Promote career

Story-wise, I almost never want to grind out a 10-level career. Right-click promote and we move on with our lives.

4. Complete aspiration goals

Aspirations bug out constantly in this game. Sometimes the game just doesn’t register that you finished a goal. UI Cheats fixes it instantly.

5. Repeal NAPs

The “Sharing is Caring” NAP is the worst thing EA ever shipped. Being able to repeal it from any mailbox without a community vote is genuinely game-saving.

6. Set relationship values

Speed-running family trees. Done. No more tedious “Get to Know” social interactions.

7. Skill levels

When I just want a chef Sim with level 10 cooking right now, I click the bar and pick 10. Two seconds.

Tips & Strategies for Using UI Cheats Sims 4

These are things I’ve picked up that aren’t obvious from the patch notes.

• Save before aggressive cheats. Dragging an age bar mid-save or changing the season randomly can cause weird interactions with autonomy. Save first, always.
• Hold Shift while clicking certain bars to deplete instead of fill (works on needs in some patches).
• Use it for testing builds. If you’re testing a house, randomize a CAS Sim, drop them in, max needs, and skip the setup grind.
• Combine with MCCC. UI Cheats and MC Command Center don’t conflict and they cover totally different stuff. Get both.
• The mod auto-detects your packs. You don’t need to enable anything for vampire cheats if you own Vampires. It just shows up.
• Right-click everything just to see. Half the cheats in this mod aren’t documented anywhere. Just right-click random panels and a menu probably exists.

Mistakes to Avoid

I see these in every Reddit thread about UI Cheats not working. Don’t be that person.

• Forgetting to enable Script Mods. This is 80% of the “it’s not working” complaints. Both checkboxes have to be on.
• Putting files too deep. Two folders deep and the script file is invisible to the game.
• Mismatched versions. If you’re on the latest game patch, you need v1.54. If you’re on an older patch, you need an older version. Don’t mix.
• Two copies in the Mods folder. If you updated the mod but didn’t delete the old version, the game can load both and break.
• Skipping the cache clear. After installing or updating, delete localthumbcache.package from your Sims 4 folder. Saves you a lot of headaches.
• Downloading from third-party sites. The malware risk is real. Only weerbesu’s Patreon.

Pro Tips for Advanced Players

For the simmers who already know the basics.

• Use UI Cheats with Better Exceptions mod. When something breaks, Better Exceptions tells you exactly which mod conflicted. UI Cheats rarely does, but if it ever fights another UI mod, this catches it.
• The randomize button in CAS (right-click the check) is a hidden gem for storytellers who want generated test characters fast.
• Right-click event goals during social events or holidays to gold-tier them when the game refuses to register completion. Bugged events are everywhere in late-game saves.
• Fix bugged Formative Moments in legacy saves by removing and re-adding them through the Traits menu (only works in v1.54+).
• Adjust eco footprint to flip a neighborhood’s vibe instantly. Drop it to -500 for green paradise, slam it to +500 for industrial wasteland aesthetic.
• For Mac users: the install path is the same as PC, just inside your Documents/Electronic Arts/The Sims 4/Mods folder. Don’t fall for guides that say Mac is different. It’s not.

Final Thoughts

UI Cheats Sims 4 is one of those mods that genuinely changes how you play this game. After v1.54 added Formative Moments, there’s basically nothing left that you can’t tweak through the UI. Weerbesu has kept this thing rock-solid for years through dozens of game patches, and it’s still 100% free.

If you’re a builder, a storyteller, a legacy player, or someone who just wants to skip the grindy parts of The Sims 4, this is the one mod I’d put above almost anything else. MCCC is great. WickedWhims has its place. But UI Cheats is the daily driver.

Drop the download, give it a session or two, and I bet you won’t load The Sims 4 without it again.
