The More Traits mod for Sims 4 allows players to assign up to 5 personality traits to adult Sims (instead of the default 3), plus additional traits for teens (4), children (3), and toddlers (2). Two main versions exist: More Traits in CAS by thepancake1 and MizoreYukii (which modifies the CAS UI directly) and More CAS Traits by Chingyu1023/Vicky Sims (offering 30 customizable options). Both mods are compatible with the base game, work with all expansion packs, and can be used together with a compatibility patch. Download links, installation instructions, and complete configuration details are provided in this guide.

Sims 4 More Traits in CAS

Have you ever felt limited by The Sims 4’s default three-trait system? Creating complex, multidimensional Sim personalities becomes frustrating when you can only choose three traits that define your entire character. The More Traits mod revolutionizes character creation by expanding trait slots across all life stages, giving your Sims the depth and personality they deserve.

This comprehensive guide covers everything you need to know about expanding trait slots in The Sims 4, including detailed comparisons of the two most popular mods, step-by-step installation instructions for both PC and Mac, complete configuration options, troubleshooting solutions, and compatibility information with other essential mods. Whether you’re new to modding or looking to optimize your existing setup, this guide provides all the answers.

Understanding the Sims 4 Trait System Limitations

The base game Sims 4 restricts players to three personality traits for Young Adults, Adults, and Elders. This limitation has frustrated players since the game’s 2014 launch, making it impossible to create truly complex characters without sacrificing important personality elements.

For example, if you want to create a creative, athletic veterinarian who loves the outdoors, you’re forced to choose between the Cat Lover trait and the Loves Outdoors trait—you can’t have both. This forces players into one-dimensional character creation that doesn’t reflect the complexity of real personalities.

The trait system becomes even more restrictive for younger Sims. Teens only get two trait slots by default, children get one, and toddlers get one. This makes it nearly impossible to distinguish between different Sims in the same household, leading to repetitive gameplay where every toddler or child feels identical.

The Two Main More Traits Mod Options

Players have two excellent choices for expanding trait slots in The Sims 4. Each mod takes a different approach to solving the trait limitation problem, and understanding the differences helps you choose the right option for your gameplay style.

More Traits in CAS by thepancake1 and MizoreYukii

The More Traits in CAS mod is the most popular choice among Sims 4 players, with hundreds of thousands of downloads across multiple platforms. Created by modders thepancake1 and MizoreYukii, this mod directly modifies the Create-A-Sim user interface to display additional trait slots visually.

Key Features:

  • Adds visual trait slots directly in the CAS interface
  • Simple one-file installation (no menu navigation required)
  • Automatic trait slot expansion: 5 for YA+, 4 for teens, 3 for children, 2 for toddlers
  • Automatically adds 5 lot trait slots (due to EA connecting CAS and lot trait systems)
  • Compatible with EA’s Discoverable Traits system (Growing Together pack)
  • Regular updates for every game patch
  • Available on Patreon (free public access)

Download Links:

This mod works immediately upon installation—simply drop the package file into your Mods folder, and the extra trait slots appear automatically in CAS. You don’t need to enable anything in-game or navigate special menus. When creating new Sims or aging up existing ones, the additional slots are immediately visible.

With the Growing Together expansion pack, Young Adults and older Sims can technically have up to 8 traits total (5 CAS traits plus 3 Discoverable Traits earned through gameplay). The game prompts you before adding Discoverable Traits, so you can reject them if you prefer to stick with your selected five CAS traits.

One important note: Infants remain at 1 trait due to game limitations and to maintain age progression balance (each life stage adds traits as Sims grow). The mod creators found that giving infants more traits caused performance issues and didn’t significantly enhance gameplay.

More CAS Traits by Chingyu1023 (Vicky Sims)

The More CAS Traits mod by Chingyu1023 (also known as Vicky Sims) offers incredible flexibility with 30 different configuration options. Unlike the thepancake1 mod, this is a tuning mod that doesn’t change the visual UI instead, you add the extra traits through gameplay menus.

Key Features:

  • 30 different trait slot configurations to choose from
  • Options range from conservative (Option 1: 5 traits for adults) to extreme (Option 30: 30 traits for adults)
  • Includes Add Traits Menu for easy trait management in gameplay
  • Optional Long-Lived Traits feature (Survivor and Lasting traits extend lifespan)
  • NPC trait spawning control (Options 1-28 give NPCs extra traits, Options 29-30 don’t)
  • Works with pets (add up to 6 traits to cats, dogs, and horses)
  • Extensive compatibility with other modders’ custom traits

Download Links:

Popular Configuration Options:

OptionInfantToddlerChildTeenYA/Adult/Elder
Option 111345
Option 712467
Option 1055161616
Option 20236912
Option 2944101520
Option 30510202530

Most players choose Option 1 (conservative), Option 7 (balanced), or Option 20 (generous) depending on their gameplay style. Options 29 and 30 prevent NPCs from spawning with excessive traits, improving game performance.

Using Both Mods Together

You can use both the More Traits in CAS mod and the More CAS Traits mod simultaneously for the best of both worlds visual UI slots from thepancake1’s mod combined with Chingyu’s flexible trait management menu. However, this requires a compatibility patch.

To use both mods together:

  1. Download the More Traits in CAS mod from thepancake1’s Patreon
  2. Download the ChingyuCompatible version specifically (listed at the bottom of the Patreon post)
  3. Download your preferred option from Chingyu’s More CAS Traits
  4. Install all files following the installation instructions below

The ChingyuCompatible file ensures the UI modifications work correctly with Chingyu’s tuning changes. Without this compatibility file, the mods will conflict and cause errors.

Complete Installation Guide (PC & Mac)

Prerequisites

Before installing any Sims 4 mods, you must enable mod support in your game:

  1. Launch The Sims 4 and load to the main menu
  2. Click Options (three dots in upper right corner)
  3. Navigate to Game Options > Other
  4. Check both boxes:
    • Enable Custom Content and Mods
    • Script Mods Allowed
  5. Click Apply Changes and restart the game

Important: You must enable these settings before installing mods. Without script mods enabled, the More CAS Traits mod won’t function.

Locating Your Mods Folder

Windows PC:

Documents\Electronic Arts\The Sims 4\Mods

Mac:

Documents/Electronic Arts/The Sims 4/Mods

If the Mods folder doesn’t exist, create it manually. The folder is case-sensitive on Mac.

Installing More Traits in CAS (thepancake1 & MizoreYukii)

  1. Visit the More Traits in CAS Patreon page (free access, no subscription required)
  2. Scroll to the bottom of the post to find download attachments
  3. Download either:
    • thepancake1-MoreTraitsInCAS-v2a.package (regular version)
    • thepancake1-MoreTraitsInCAS-v2a-ChingyuCompatible.package (if using with Chingyu’s mod)
  4. Extract the downloaded file if it’s in a ZIP archive
  5. Place the .package file directly in your Mods folder or one subfolder deep

Critical Rule: Package files can be up to 5 folders deep, but it’s best practice to keep them organized in subfolders. For example:

  • ✅ Mods/More Traits/thepancake1-MoreTraitsInCAS-v2a.package
  • ✅ Mods/thepancake1-MoreTraitsInCAS-v2a.package
  1. Clear your game cache:
    • Navigate to Documents\Electronic Arts\The Sims 4
    • Delete these files: localthumbcache.package and all files in the avatarcache folder
    • These regenerate automatically when you launch the game
  2. Launch The Sims 4 and test in Create-A-Sim

Installing More CAS Traits (Chingyu/Vicky Sims)

  1. Visit Vicky Sims’ More CAS Traits page
  2. Download the “MoreTraitsMod_Options” ZIP file
  3. Download the “AddTraitsMenu” ZIP file (essential for adding traits in-game)
  4. Optional: Download “Long-Lived Traits” if desired

For MoreTraitsMod_Options:

  1. Extract the ZIP file—you’ll see 30 different .package files (Options 1-30)
  2. Choose ONLY ONE option that matches your desired trait numbers
  3. Place your selected option file in your Mods folder (up to 5 folders deep)

For AddTraitsMenu:

  1. Extract the ZIP—you’ll see two files:
    • chingyu_AddTraitsMenu.package
    • chingyu_AddTraitsMenu.ts4script
  2. Both files must be placed together no more than one subfolder deep:
    • ✅ Mods/chingyu_AddTraitsMenu.package and .ts4script
    • ✅ Mods/Chingyu/chingyu_AddTraitsMenu.package and .ts4script
    • ❌ Mods/Scripts/Chingyu/Files/... (too deep, won’t work)

Critical Script Mod Rule: The .ts4script file MUST be one folder deep maximum or it won’t load. This is a hard-coded Sims 4 limitation.

  1. Launch The Sims 4
  2. Load any household
  3. Click on a Sim and select Actions > Add or Remove traits

How to Use Each Mod?

Using More Traits in CAS (thepancake1)

Once installed, this mod works automatically:

For New Sims:

  1. Enter Create-A-Sim (main menu or in-game)
  2. Notice the additional trait slots based on life stage
  3. Select traits normally all slots function identically to the default three

For Existing Sims:

  1. Enable cheats: Press Ctrl+Shift+C (PC) or Cmd+Shift+C (Mac)
  2. Type testingcheats true and press Enter
  3. Type cas.fulleditmode and press Enter
  4. Close the cheat console (press Escape)
  5. Hold Shift and click on your Sim
  6. Select Modify in CAS
  7. Add traits to the newly visible slots
  8. Click the checkmark to save changes

You don’t need to fill all trait slots. Sims can exist with fewer than the maximum available traits.

Using More CAS Traits (Chingyu)

This mod requires using the Add Traits Menu in gameplay:

Adding Traits:

  1. Load any household
  2. Click on any Sim (including pets)
  3. Select Actions from the pie menu
  4. Choose Add to open the traits list
  5. Select the trait you want to add
  6. Repeat for additional traits up to your chosen option’s limit

Removing Traits:

  1. Click on the Sim
  2. Select Actions > Remove
  3. Choose the trait to remove

Changing Personality Traits (Self Sim Only):

  1. Click on your controlled Sim
  2. Select Actions > Change Personality Traits
  3. This option shows a maximum of 3 traits (base game limitation)
  4. Use Add/Remove for traits beyond the first three

Important: The visual CAS interface won’t display extra traits when using Chingyu’s mod alone. All trait management happens through gameplay menus. If you want both visual slots AND menu management, use both mods with the compatibility patch.

Configuration Options Explained

Choosing the Right Trait Number

Players often struggle with deciding how many traits to give their Sims. Here’s guidance based on different gameplay styles:

Conservative Players (Options 1-5):

  • Prefer subtle enhancements to base game
  • Want improved personality without overwhelming complexity
  • Recommended: Option 1 (5 traits for adults)
  • Best for players new to the More Traits mod

Balanced Players (Options 6-15):

  • Want noticeable personality depth
  • Enjoy creating complex characters without excessive micromanagement
  • Recommended: Options 7-12 (6-8 traits for adults)
  • Popular with storytelling-focused players

Maximum Depth Players (Options 16-28):

  • Want extremely detailed personalities
  • Play with extensive custom trait collections
  • Recommended: Options 18-22 (10-14 traits for adults)
  • Best for experienced players with many custom traits installed

Performance-Conscious Players (Options 29-30):

  • Want lots of traits for controlled Sims
  • Don’t want NPCs spawning with excessive traits (game performance)
  • Prevents townies from having 20+ traits slowing down your game
  • Recommended for players with large households or slower computers

NPC Trait Spawning Explained

When you use Options 1-28, randomly generated NPCs (townies, service workers, etc.) automatically receive the number of traits specified by your option. For example, with Option 20 (12 traits for adults), every newly spawned townie will have 12 random traits.

Pros of NPC trait spawning:

  • More interesting and diverse townies
  • NPCs feel more like real Sims with complex personalities
  • Better for immersive, realistic gameplay

Cons of NPC trait spawning:

  • Can slow down game performance with hundreds of NPCs
  • NPCs might have conflicting or nonsensical trait combinations
  • Increases save file size

Options 29 and 30 disable automatic NPC trait assignment. Randomly generated Sims will spawn with base game trait numbers (3 for adults), but you can still manually add extra traits using the Add Traits Menu. This provides the best of both worlds—detailed controlled Sims without performance impact from NPC traits.

Long-Lived Traits Feature

The Long-Lived Traits addon includes two special traits that extend Sim lifespans:

Survivor Trait:

  • Adds 20% bonus days to total lifespan
  • Example: Normal lifespan adults live 90 days, Survivor adults live 108 days
  • Permanent trait, cannot be removed except with trait removal cheats
  • Available in reward store with XML Injector installed

Lasting Trait:

  • Adds 35% bonus days to total lifespan
  • Example: Normal lifespan adults live 90 days, Lasting adults live 121.5 days
  • Stackable with Survivor if both are added (55% total increase)
  • Ideal for legacy gameplay or favorite Sims you don’t want to lose

Both traits require having at least one More Traits option file installed to function. They don’t work as standalone traits.

Troubleshooting Common Issues

Extra Trait Slots Not Appearing (thepancake1 Mod)

Problem: Installed the mod but don’t see extra trait slots in CAS.

Solutions:

  1. Verify mods are enabled:
    • Check Game Options > Other > Enable Custom Content and Mods
    • Check Game Options > Other > Script Mods Allowed
    • Both must be checked
  2. Check game version compatibility:
    • Visit the Patreon page
    • Verify the mod version matches your game patch
    • The Sims 4 updates frequently, mods must be updated too
  3. Clear game cache:
    • Delete localthumbcache.package and avatarcache folder contents
    • Located at: Documents\Electronic Arts\The Sims 4
    • Restart the game
  4. Check file placement:
    • Ensure the .package file is in the correct location
    • Maximum 5 folders deep, but preferably only 1-2 folders deep
  5. Remove conflicting mods temporarily:
    • Disable other CAS-modifying mods
    • Test with only More Traits installed
    • Re-enable mods one at a time to identify conflicts

Add Traits Menu Not Appearing (Chingyu Mod)

Problem: Can’t find the Add/Remove traits option when clicking on Sims.

Solutions:

  1. Verify script mod placement:
    • The .ts4script file MUST be one folder deep maximum
    • Move both files (.package and .ts4script) to proper location
    • Correct: Mods/chingyu_AddTraitsMenu.ts4script
    • Incorrect: Mods/Scripts/Gameplay/chingyu_AddTraitsMenu.ts4script
  2. Ensure both files are present:
    • Check that both .package AND .ts4script files are in the same folder
    • Missing either file prevents the menu from working
  3. Restart after installation:
    • Fully exit The Sims 4
    • Relaunch the game
    • Script mods require full restart to load
  4. Check for mod updates:

Game Crashes or Last Exception Errors

Problem: Game crashes when entering CAS or after adding traits.

Solutions:

  1. Install Better Exceptions mod:
    • Essential diagnostic tool by TwistedMexi
    • Identifies exactly which file is causing crashes
    • Provides actionable error reports
  2. Update all mods:
    • After each Sims 4 patch, mods often break
    • Visit all mod creators’ pages to download updates
    • Never use outdated mod versions after patches
  3. Remove broken custom traits:
    • Some older custom traits may be incompatible
    • Better Exceptions will identify problematic traits
    • Remove or update conflicting custom trait files
  4. Check mod conflict list:
    • Visit the mod creator’s page for known conflicts
    • Remove or update conflicting mods
    • Test with minimal mods to isolate issues
  5. Repair game files:
    • In Origin/EA App: Right-click The Sims 4 > Repair
    • This fixes corrupted game files
    • Your mods and saves remain intact

Traits Not Saving After CAS Edit

Problem: Add traits in CAS but they disappear when returning to gameplay.

Solutions:

  1. Use cas.fulleditmode correctly:
    • Enable testingcheats first: testingcheats true
    • Then enable full edit: cas.fulleditmode
    • Must be done in this order every game session
  2. Click the checkmark to save:
    • After adding traits, click the green checkmark in CAS
    • Don’t exit CAS with the X button
    • Exiting without saving discards changes
  3. Check for UI glitches:
    • EA fixed many CAS UI glitches in recent patches
    • Ensure your game is fully updated
    • Update More Traits mod to latest version
  4. Try adding traits through gameplay instead:
    • If CAS editing fails, use Chingyu’s Add Traits Menu
    • Compatible with thepancake1’s mod
    • Download Add Traits Menu as a standalone option

Performance Issues After Installing

Problem: Game runs slower, lags in CAS, or has longer loading screens.

Solutions:

  1. Choose a lower trait option:
    • Options 29-30 prevent NPC trait spawning
    • Reduces processing load from hundreds of townies
    • Maintains trait depth for your controlled Sims
  2. Clean up your save file:
    • Use MCCC’s Clean mod function
    • Removes orphaned data and reduces save file size
    • Improves overall game performance
  3. Limit active traits:
    • Don’t feel obligated to fill all trait slots
    • 5-7 well-chosen traits provide depth without overwhelming the game
    • More traits = more autonomous behavior calculations
  4. Optimize your Mods folder:
    • Use a mod manager to organize files
    • Remove unused mods and custom content
    • Merged .package files load faster than many separate files

Advanced Features and Tips

Combining with Custom Trait Mods

The true power of the More Traits mods emerges when combined with custom trait packs. With only the base game’s limited traits, even 5 trait slots aren’t enough to create truly unique Sims. Custom trait collections expand your options to hundreds or even thousands of traits.

Recommended Custom Trait Collections:

Chingyu’s 100 Base Game Traits Pack:

  • Over 100 custom traits requiring only base game
  • Includes personality traits, skill traits, emotional traits
  • Available on CurseForge
  • Created by the same modder as More CAS Traits
  • Seamlessly integrated with Add Traits Menu

Maplebell’s More Traits Series (#1-4):

  • Unique, creative traits across four packs
  • Examples: Cuddle Bug, Fairy-Tale Fanatic, Baker, Memory Keeper
  • Each pack contains 10-20 traits
  • Base game compatible with enhanced functionality with packs
  • Available on Patreon

Kuttoe’s New Emotional Traits:

  • Extreme versions of existing traits
  • Focused on emotional depth and reactions
  • Includes Egghead, Restless, Type A personality traits
  • Requires base game only
  • Available on itch.io

Installation tip: When using 50+ custom traits, consider organizing them into themed folders (Emotional Traits, Career Traits, Hobby Traits, etc.) within your Mods folder for easier management.

Pet Trait Management

Chingyu’s More CAS Traits mod includes special functionality for pets (requires Cats & Dogs or Horse Ranch expansion packs):

Adding Pet Traits:

  1. Click on any cat, dog, or horse
  2. Select Actions > Add
  3. You can add up to 6 personality traits total (3 default + 3 extra)
  4. Mix regular pet traits with hidden traits

Important Notes:

  • Randomly generated strays and NPC pets won’t auto-spawn with extra traits (prevents performance issues)
  • You can manually add extra traits to any stray or adopted pet
  • The DisallowHumanTraitsForPets package (old addon) is no longer needed after patch 1.96
  • Human traits cannot be added to pets (game limitation)

Using Trait Randomizers

Some players enjoy using trait randomizers for challenge gameplay:

Sims 4 Random Trait Generator websites:

  • Generate random trait combinations for new Sims
  • Particularly useful with 5+ trait slots
  • Creates unexpected, challenging personality combinations

Integration with gameplay:

  1. Use random trait generator to create trait list
  2. Open CAS or Add Traits Menu
  3. Manually add the generated traits to your Sim
  4. Adapt gameplay to unexpected personality

This method works excellently for legacy challenges, storylockes, or any gameplay where you want unpredictable Sims.

Testing Trait Combinations

With 5+ trait slots, some trait combinations create unintended conflicts or synergies:

Conflicting Traits (avoid combining):

  • Active + Lazy (conflicting autonomous behaviors)
  • Neat + Slob (opposing personality types)
  • Loner + Outgoing (contradictory social preferences)
  • Vegetarian + Glutton (frequent discomfort from eating)

Synergistic Traits (powerful combinations):

  • Genius + Bookworm + Ambitious (perfect for academic careers)
  • Active + Outdoorsy + Loves Swimming (ideal for island living)
  • Creative + Art Lover + Perfectionist (master painter/musician combo)
  • Cat Lover + Dog Lover + Animal Enthusiast (ultimate pet owner)

Testing methodology:

  1. Create test Sim with specific trait combination
  2. Play for 1-2 Sim weeks
  3. Note autonomous behaviors, mood changes, and conflicts
  4. Document particularly effective or problematic combinations
  5. Apply learnings to future Sims

Frequently Asked Questions (FAQ)

Does the More Traits mod work with all expansion packs?

Yes, both the More Traits in CAS mod and the More CAS Traits mod are fully compatible with all expansion packs, game packs, stuff packs, and kits. The mods work with the base game alone and automatically integrate with any expansion pack traits you own. When new packs release, the mod creators typically update their mods within 24-48 hours to ensure compatibility with the latest patch.

Can I use both More Traits mods at the same time?

Yes, you can use both thepancake1’s More Traits in CAS and Chingyu’s More CAS Traits simultaneously, but you must download the ChingyuCompatible version of thepancake1’s mod. This compatibility file is available at the bottom of the More Traits in CAS Patreon post. Without the compatibility patch, the mods will conflict and cause errors. When properly installed together, you’ll have visual trait slots in CAS plus the Add Traits Menu for in-game trait management.

How do I add traits to existing Sims after installing the mod?

For thepancake1’s More Traits in CAS mod, enable cheats by pressing Ctrl+Shift+C and typing testingcheats true, then type cas.fulleditmode. Hold Shift, click on your Sim, and select “Modify in CAS” to access the additional trait slots. For Chingyu’s More CAS Traits mod, simply click on any Sim in gameplay, select “Actions,” then choose “Add” to open the traits menu. Both methods work with existing Sims without requiring you to recreate them.

Will this mod work on consoles (PlayStation/Xbox)?

No, neither the More Traits in CAS mod nor the More CAS Traits mod works on PlayStation or Xbox. The Sims 4 on consoles does not support script mods or UI modifications due to Sony and Microsoft’s restrictions on mod functionality. These mods only work on PC (Windows) and Mac versions of The Sims 4 through Origin, Steam, or the EA App. Console players are limited to the base game’s three trait slots for adults.

Does the More Traits mod affect game performance?

Yes, adding more traits can impact game performance, especially if you choose options with many traits for adults (10+) or if you allow NPCs to spawn with extra traits. More traits mean more autonomous behaviors for the game to calculate, which can slow down gameplay on older computers. To minimize performance impact, choose Options 29 or 30 from Chingyu’s mod (these prevent NPCs from auto-spawning with extra traits) or select a conservative option like Option 1. You can also limit your own Sims to 5-7 well-chosen traits rather than maximizing all slots.

Can I change how many trait slots different age groups have?

With thepancake1’s More Traits in CAS mod, the trait slot numbers are fixed (5 for YA+, 4 for teens, 3 for children, 2 for toddlers, 1 for infants). However, with Chingyu’s More CAS Traits mod, you can choose from 30 different configurations that adjust trait numbers for each life stage. For example, Option 7 gives toddlers 2 traits, children 4, teens 6, and adults 7. Simply download a different option file to change your configuration. You can only use one option at a time, so removing the old option and installing a new one changes your trait slot numbers.

Will my Sims lose their extra traits if I uninstall the mod?

If you uninstall the More Traits mod, your Sims will keep the extra traits in their character data, but you won’t be able to manage them or see them in CAS. The traits will still technically exist and may affect behavior, but they’ll be invisible. If you’re planning to remove the mod, it’s best to remove extra traits first (keep only 3 for adults) before uninstalling. For thepancake1’s mod, use cas.fulleditmode to remove extras. For Chingyu’s mod, use the Remove option in the Actions menu to clean up traits before uninstalling.

Why can’t infants have more than 1 trait?

The mod creators (both thepancake1 and Chingyu) designed the mods to keep infants at 1 trait for balance and performance reasons. Infants have extremely limited gameplay interactions compared to other life stages, so additional traits don’t meaningfully enhance their gameplay. Furthermore, having each life stage gain traits as Sims age up (1 for infant, 2 for toddler, 3 for child, etc.) creates a natural progression system. Testing also showed that giving infants multiple traits caused performance issues without adding significant gameplay value.

Do I need to enable testingcheats to use these mods?

For thepancake1’s More Traits in CAS mod, you only need testingcheats enabled if you’re editing existing Sims with cas.fulleditmode. Creating new Sims works without any cheats. For Chingyu’s More CAS Traits mod, you don’t need any cheats enabled at all—the Add Traits Menu functions without requiring testingcheats true. However, both mods require that you have “Enable Custom Content and Mods” and “Script Mods Allowed” checked in your Game Options, which is different from enabling the cheat console.

Can I use these mods with other CAS-modifying mods?

The More Traits mods are compatible with most CAS-enhancing mods. They work perfectly with More Columns in CAS, UI Cheats Extension, and various CAS background replacements. However, avoid using multiple mods that modify the same CAS UI elements. If you experience issues, temporarily disable other CAS mods and test with only More Traits installed to identify conflicts. Most modern CAS mods are designed with compatibility in mind, so conflicts are rare.

How often do these mods need to be updated?

Both More Traits mods require updates after nearly every major Sims 4 patch, especially when EA releases expansion packs or game updates that modify the CAS system. thepancake1 and MizoreYukii typically update More Traits in CAS within 24-48 hours of a new patch. Chingyu usually updates the More CAS Traits options within a similar timeframe. You should check the mod creators’ pages after every game update and download the newest version. Using outdated mod versions after patches is the most common cause of game crashes and errors with The Sims 4 mods.

Conclusion: Elevate Your Sims 4 Experience

The More Traits mod transforms The Sims 4 from a game of simplified personalities into a rich character simulation where your Sims truly feel unique and multidimensional. Whether you choose thepancake1’s elegant UI modification, Chingyu’s flexible configuration system, or both mods working in harmony, you’ll never return to the limiting three-trait system.

With up to 5 traits for adults (or more with Chingyu’s expanded options), your creative scientist can also be an outdoorsy dog lover. Your ambitious businessperson can simultaneously be neat, perfectionist, and family-oriented. The combinations become nearly endless, especially when paired with custom trait collections and other essential Sims 4 mods.

Remember these key takeaways:
