Total Makeover: How to Change Your Sims 4 Traits and Appearance

The Sims 4 offers a robust character creation tool, allowing you to craft unique Sims with distinct personalities and looks. However, life in the virtual world can be unpredictable. Perhaps your Sim’s initial aspiration no longer aligns with their gameplay, or maybe you simply want to refresh their appearance. Thankfully, The Sims 4 provides several methods to alter your Sim’s traits and appearance even after they’ve moved into their virtual home.

This guide will delve into the various techniques you can use to give your Sim a makeover, covering everything from using cheats to leveraging in-game items and expansions. We’ll provide detailed, step-by-step instructions to ensure you can successfully transform your Sim into the Sim of your dreams.

## Method 1: The Time-Tested Cheat Codes

The most straightforward and often quickest way to change your Sim’s traits and appearance is by utilizing cheat codes. This method is particularly useful if you want to make drastic changes or address something quickly without going through elaborate in-game processes.

**1. Enabling Cheats:**

Before you can start altering your Sim, you need to enable cheats. The method for doing this varies depending on your platform:

* **PC:** Press `Ctrl + Shift + C` simultaneously. This will open the cheat console at the top of the screen.
* **Mac:** Press `Command + Shift + C` simultaneously to open the cheat console.
* **PlayStation 4 & 5:** Press `L1 + R1 + L2 + R2` simultaneously.
* **Xbox One & Series X/S:** Press `LB + RB + LT + RT` simultaneously.

In the cheat console, type `testingcheats true` and press Enter. This activates the testing cheats mode, allowing you to use more advanced commands. You should see a message confirming that cheats are enabled.

**2. Accessing CAS (Create-a-Sim) with Cheats:**

Once testing cheats are enabled, you can access the full CAS interface to modify your Sim’s appearance and traits. Type the following cheat code into the console and press Enter:

`cas.fulleditmode`

This command unlocks all CAS features, including the ability to change your Sim’s gender, age, and pre-set Sims. Without this cheat, some features might be locked, preventing you from making complete changes.

**3. Interacting with Your Sim:**

Now that you’ve unlocked full CAS access, you have a couple of options to actually trigger the CAS interface:

* **Option 1: Shift-Clicking:** Shift-click on the Sim you want to edit. A menu will appear. Select “Modify in CAS.” This will immediately transport you to the Create-a-Sim screen with your chosen Sim loaded.
* **Option 2: Using the Mirror or Dresser:** Click on any mirror or dresser in your Sim’s home. Select “Plan Outfit.” If the `cas.fulleditmode` cheat is active, this will also open the full CAS interface instead of just allowing you to change outfits.

**4. Making Your Changes in CAS:**

In the Create-a-Sim screen, you can now freely modify your Sim’s:

* **Appearance:** Change their hairstyle, facial features, body shape, skin tone, eye color, and clothing. You have access to all clothing items in your game, including those typically locked to specific ages or genders (if you’ve removed the gender preference filter in the settings).
* **Traits:** Click on the “Traits” panel (usually located near the Sim’s name and aspiration). You can then remove existing traits and add new ones. Remember that Sims can have a maximum of three personality traits as adults and children, and toddlers have one trait.
* **Aspiration:** You can change your Sim’s aspiration, which influences their whims and long-term goals. Consider how the new aspiration will complement their traits and lifestyle.
* **Name:** You can also rename your Sim in CAS.

**5. Saving Your Changes:**

Once you’re satisfied with the changes, click the checkmark in the bottom right corner of the screen. This will save your modifications and return you to the game with your newly transformed Sim.

**Important Considerations when Using Cheats:**

* **Game Instability:** While generally safe, using cheats excessively or incorrectly can sometimes lead to minor glitches or game instability. Save your game before using any cheat codes to prevent potential data loss.
* **Gameplay Experience:** Over-reliance on cheats can diminish the intended gameplay experience. Consider using them strategically to enhance your game rather than completely bypass challenges.
* **Achievement Blocking:** In some cases, using cheats may disable certain achievements or milestones. If you are an achievement hunter, be mindful of this.

## Method 2: The Re-Traiting Potion (Reward Store)

For a more integrated and less cheat-dependent approach, you can use the Re-Traiting Potion. This potion allows you to change your Sim’s traits without using cheat codes, offering a more organic way to evolve their personality.

**1. Earning Satisfaction Points:**

The Re-Traiting Potion is purchased using Satisfaction Points. Satisfaction Points are earned by completing whims and aspirations. Whims are small, short-term goals that appear in the bottom left corner of the screen. Aspirations are longer-term goals that you set for your Sim. Fulfilling these desires grants you Satisfaction Points.

* **Completing Whims:** Pay attention to your Sim’s whims and actively try to fulfill them. These often involve simple tasks like socializing, cooking, or pursuing hobbies.
* **Achieving Milestones in Aspirations:** Progressing through the milestones of your chosen aspiration provides significant Satisfaction Point rewards. Focus on completing the tasks outlined in your aspiration panel.

**2. Accessing the Reward Store:**

Once you’ve accumulated enough Satisfaction Points, open the Aspiration panel (usually located in the bottom right corner of the screen, represented by a diamond icon). In the Aspiration panel, click the “Rewards Store” button.

**3. Purchasing the Re-Traiting Potion:**

In the Rewards Store, scroll through the available items until you find the “Re-Traiting Potion.” This potion typically costs 5,000 Satisfaction Points. Click on the potion and then click the “Purchase” button.

**4. Using the Potion:**

After purchasing the potion, it will appear in your Sim’s inventory. Click on the potion in the inventory and select “Drink.” Your Sim will then consume the potion.

**5. Selecting New Traits:**

After drinking the Re-Traiting Potion, a pop-up window will appear, allowing you to select new traits for your Sim. You can choose any trait available in the game, but remember the limit of three traits for adults and children, and one trait for toddlers. Take some time to consider which traits best suit your Sim’s current lifestyle and aspirations.

**Advantages of Using the Re-Traiting Potion:**

* **No Cheats Required:** This method provides a legitimate, in-game way to change traits without using cheat codes.
* **Engaging Gameplay:** Earning Satisfaction Points through gameplay encourages you to actively engage with your Sim’s aspirations and whims.
* **Storytelling Opportunities:** Changing traits can be a significant event in your Sim’s life, opening up new storytelling possibilities.

**Disadvantages of Using the Re-Traiting Potion:**

* **Time-Consuming:** Earning enough Satisfaction Points to purchase the potion can take a considerable amount of time, especially if you’re starting from scratch.
* **Limited to Traits:** This method only allows you to change traits, not appearance.

## Method 3: Plastic Surgery (Discover University Expansion Pack)

If you own the Discover University expansion pack, you can utilize the Plastic Surgery interaction to alter your Sim’s facial features. This method provides a more limited but still useful way to change your Sim’s appearance without relying on cheat codes.

**1. Having a Sim with a Degree in Biology:**

One of the ways to unlock the plastic surgery ability is by having a Sim who has graduated with a degree in Biology from the University. This will give them a career opportunity to perform plastic surgery on other sims.

**2. Finding a Mirror:**

Find any mirror in your Sim’s home or in a public place. Click on the mirror to bring up the interaction menu.

**3. Selecting “Plastic Surgery”:**

If you are using a sim that has graduated with a Biology degree and has the plastic surgery opportunity, then you will see the option “Plastic Surgery”. If you do not have this then this step cannot be accomplished.

**4. Modifying Facial Features:**

The CAS interface will open, but with limited functionality compared to using the `cas.fulleditmode` cheat. You will only be able to modify your Sim’s facial features, such as their nose, eyes, mouth, and jawline. You cannot change their hairstyle, body shape, or clothing.

**5. Saving Changes:**

Click the checkmark in the bottom right corner of the screen to save your changes and return to the game.

**Advantages of Plastic Surgery:**

* **No Cheats Needed:** This method is a legitimate in-game interaction.
* **Focused Facial Adjustments:** Allows for precise modifications to facial features.

**Disadvantages of Plastic Surgery:**

* **Requires Discover University:** This method is only available if you own the Discover University expansion pack.
* **Limited Scope:** Only allows changes to facial features; it does not allow for changing traits, body shape, or other aspects of appearance.
* **Specific Requirements:** Requires a University degree or a high level in the medical career.

## Method 4: The Master Controller Mod (For Advanced Players)

For players who are comfortable using mods, the Master Controller mod by Twallan is a powerful tool that offers extensive control over your Sims and their world. This mod allows you to access CAS directly, change traits, relationships, and many other aspects of the game.

**1. Downloading and Installing the Master Controller Mod:**

* **Find a Reputable Source:** Download the Master Controller mod from a reputable source like NRaas Industries ([https://www.nraas.net/](https://www.nraas.net/)). Ensure you download the version compatible with your current Sims 4 game version.
* **Extract the Files:** Extract the downloaded ZIP file. You should find one or more `.package` files.
* **Place Files in the Mods Folder:** Place the `.package` files into your Sims 4 Mods folder. This folder is typically located in `Documents\Electronic Arts\The Sims 4\Mods`. If a Resource.cfg file isn’t present, create one with the following content:

Priority 500
PackedFile *.package
PackedFile *.zip

* **Enable Custom Content:** In The Sims 4, go to Options -> Game Options -> Other and enable “Enable Custom Content and Mods” and “Script Mods Allowed.” Restart your game for the changes to take effect.

**2. Using Master Controller to Edit Sims:**

* **Click on Your Sim:** In live mode, click on the Sim you want to edit.
* **Select NRaas -> Master Controller -> Advanced -> Edit in CAS:** This will open the full Create-a-Sim interface for your chosen Sim.
* **Make Your Changes:** As with the cheat code method, you can now freely modify your Sim’s appearance, traits, aspiration, and name.
* **Save Your Changes:** Click the checkmark in the bottom right corner to save your modifications.

**Advantages of Using the Master Controller Mod:**

* **Full CAS Access:** Provides unrestricted access to the Create-a-Sim interface.
* **Extensive Control:** Offers numerous other features beyond just editing Sims, such as managing relationships, pregnancies, and populations.
* **Customization:** Allows for highly customized gameplay experiences.

**Disadvantages of Using the Master Controller Mod:**

* **Requires Modding:** Involves downloading and installing a third-party mod, which may be intimidating for some players.
* **Potential Conflicts:** Mods can sometimes conflict with each other or with game updates, potentially causing issues. Regularly update your mods and be cautious when adding new ones.
* **Learning Curve:** The Master Controller mod has many features, so it may take some time to learn how to use it effectively.

## Method 5: In-Game Items and Interactions (Limited Changes)

While not providing a full makeover, certain in-game items and interactions can subtly alter your Sim’s appearance or personality.

**1. Mirrors and Dressers:**

* **Change Outfits:** The most basic function of mirrors and dressers is to change outfits. You can select from your Sim’s existing wardrobe or purchase new clothing items.
* **Change Hairstyle and Makeup:** Sims can also change their hairstyle and makeup at mirrors. This allows for minor adjustments to their appearance.

**2. Careers and Skills:**

* **Career Outfits:** Certain careers unlock unique outfits that your Sim will wear while at work. These outfits can sometimes influence your Sim’s overall style.
* **Skill-Based Changes:** Some skills can indirectly affect your Sim’s appearance. For example, Sims with high fitness skills may develop more muscular physiques.

**3. Relationships and Experiences:**

* **Relationship Influences:** Your Sim’s relationships can influence their personality and behavior over time. Positive relationships can lead to happier and more outgoing Sims, while negative relationships can lead to sadness or anger.
* **Life Experiences:** Major life events, such as marriage, childbirth, or the death of a loved one, can significantly impact your Sim’s emotional state and personality.

**4. Spa Day Pack:**

* **New Hairstyles and Clothing:** The Spa Day Game Pack comes with new hairstyles, clothing, and accessories that your Sims can use.
* **Wellness Skill:** Sims who develop their wellness skill can perform yoga, meditation, and give massages, which can impact their emotional state.

**Advantages of In-Game Items and Interactions:**

* **Natural Progression:** These methods allow for a more natural and gradual evolution of your Sim’s appearance and personality.
* **Immersive Gameplay:** Integrates seamlessly into the existing gameplay experience.

**Disadvantages of In-Game Items and Interactions:**

* **Limited Control:** Provides less direct control over specific traits or appearance features.
* **Slow Process:** Changes are gradual and may take a significant amount of time to become noticeable.

## Method 6: Story Progression and Aging (Natural Changes)

The Sims 4’s story progression and aging system naturally influence your Sim’s development. As Sims age, their appearance changes, and they may develop new traits based on their life experiences.

**1. Aging:**

* **Toddlers:** Gain a single trait.
* **Children:** Gain up to three traits.
* **Teenagers:** Develop their sense of style and explore different interests.
* **Adults:** Establish their careers and families, further shaping their personalities.
* **Elders:** Reflect on their lives and experiences.

**2. Story Progression:**

* **Neighborhood Stories:** With Neighborhood Stories enabled (added in a free patch), Sims in your neighborhood can autonomously get married, have children, change careers, and even die. These events can influence your Sim’s relationships and emotional state.
* **Autonomy:** Allow your Sims to make their own choices and pursue their own interests. This can lead to unexpected and interesting developments in their personalities and lives.

**Advantages of Story Progression and Aging:**

* **Realistic Development:** Sims evolve naturally over time, reflecting their life experiences.
* **Unpredictability:** Adds an element of surprise and challenge to the gameplay experience.

**Disadvantages of Story Progression and Aging:**

* **Limited Control:** You have less direct control over how your Sims develop.
* **Unforeseen Consequences:** Story progression can sometimes lead to unexpected or undesirable outcomes.
