Enter the Sims 4 CAS cheat—a powerful tool that lets you bypass the usual game restrictions and fully edit your Sims, from their appearance to their traits and relationships.

In this guide, we’ll show you how to activate and make the most of the CAS cheat step-by-step, explore its capabilities, address troubleshooting issues, and even answer some of the most frequently asked questions about this game-changing feature.

What is the Sims 4 CAS Cheat and Why Should You Use It?

The Create-A-Sim cheat, or CAS cheat, in The Sims 4 is a command that allows players to unlock a “full edit” mode for their Sims. Normally, once you’ve entered the game, certain aspects of your Sims become locked—you can’t edit their age, traits, or family connections, for instance. But with the CAS cheat, the possibilities are endless. Whether you want to tweak your Sim’s physical appearance, rename them, or even redefine their relationships, this cheat can help you achieve it all. The CAS cheat is a favorite among players who enjoy storytelling, character customization, and creating unique households tailored to specific narratives.

How to Enable Cheats in Sims 4 – A Step-by-Step Guide

Before you can dive into the world of full Sim customization, you need to enable cheats in your game. Here’s how to get started:

Step 1: Open the Cheat Console

  • PC: Press Ctrl + Shift + C simultaneously.
  • Mac: Press Command + Shift + C simultaneously.
  • PlayStation: Press L1 + L2 + R1 + R2 together.
  • Xbox: Press LT + RT + LB + RB at the same time.

This will open the cheat console at the top of your screen—a box where you can write and input your cheat commands.

Step 2: Turn On Cheats

To enable all cheats in the game, type testingcheats true or testingcheats on into the console and hit Enter. A message should appear indicating that cheats are now enabled.

Activating Full Edit Mode for CAS

Once cheats are enabled, the next step is to activate the CAS full edit mode. Here’s a simple guide on how to do it:

Step 1: Enter the CAS Cheat

While the cheat console is still open, type cas.fulleditmode and press Enter. This command allows you to bypass the standard restrictions on editing Sims.

Step 2: Modify Your Sim

To actually start editing a Sim, hold the Shift key and click on the Sim you wish to edit. On consoles, use the corresponding controller buttons. A pie menu will appear—select the option “Modify in CAS.” This will take you straight into the Create-A-Sim interface with full editing capabilities unlocked.

Features Unlocked with the CAS Cheat

When the CAS full edit mode is active, you’ll gain access to a wide range of customization options for your Sims. Here’s what you can do:

Appearance

  • Modify any physical feature, including body type, weight, muscle tone, facial structure, and every tiny detail of your Sim’s face.
  • Change hairstyles, hair colors, and add or remove accessories.
  • Select new outfits for every life stage—from everyday wear to swimwear and formal attire.
  • Adjust occult forms, such as alien disguises or vampire dark forms.

Personality and Traits

  • Alter your Sim’s traits to fit a new storyline or personality type.
  • Edit their aspirations, allowing you to change long-term goals easily.
  • Switch up likes and dislikes to redefine their preferences in decor, music, or hobbies.

Life Stage and Gender

  • Change your Sim’s age. Want an elder Sim to become a toddler? The CAS cheat makes it a breeze.
  • Edit gender settings. You can adjust voice, clothing preferences, or pregnancy capabilities.

Relationships

  • Edit family relationships—it’s simple to set who counts as a parent, sibling, spouse, or child.
  • Break existing familial ties or create entirely new ones.

How to Use the Sims 4 CAS Cheat Like a Pro

Now that you understand the basics of the CAS cheat, it’s time to refine your skills and use this tool like a pro. Here are some expert tips to get the most out of it:

1. Plan Your Sim in Advance

  • Before jumping into CAS full edit mode, consider what specific changes you want to make.
  • Write down details like potential family dynamics, personality traits, or physical features you’d like to include.

2. Use Shift-Click on NPCs

The CAS cheat isn’t just for your household Sims—you can also use it to modify non-playable characters (NPCs). Simply shift-click on any NPC, select “Modify in CAS,” and make the changes you want!

3. Save Frequently

Editing your Sims can get carried away quickly, especially when accessing CAS full edit mode. Save your game frequently to avoid losing progress to crashes or accidents.

Using Mods to Expand CAS Features

The Sims 4 modding community has created fantastic additions to enhance the CAS experience. Popular CAS mods include:

  • Extra trait slots that let you assign more personality traits.
  • Custom content (CC) options for hair, outfits, and accessories.
  • Advanced relationship mods for even more complex family dynamics.

Check out platforms like The Sims Resource, ModTheSims, and Nexus Mods for more options.

Troubleshooting and CAS Cheat Issues

While the CAS cheat is incredibly useful, you might encounter some challenges along the way. Here are common problems and how to resolve them:

Issue: Cheats Are Not Working

Solution: Double-check that you’ve activated cheats using testingcheats true. If mods or custom scripts are running, they could cause conflicts—disable or update them.

Issue: Sims Not Editable

Solution: Confirm that you entered cas.fulleditmode before trying to modify the Sim. Restart your game if the issue persists.
