If you enjoy adding more personality and variety to your Sims, ThePancake1 More Traits in CAS is a popular mod to explore. It expands the number of traits available in Create-a-Sim (CAS), giving you more ways to shape your Sims’ personalities, interests, and everyday behavior. Instead of being limited to the standard trait options, this mod can help make your Sims feel more unique.
Installing a CAS trait mod can be confusing if you have never worked with Sims 4 custom content before. You may want to know where to download ThePancake1 More Traits in CAS, how to install the files correctly, and what to do if the traits do not appear in CAS. A few simple steps can help you avoid common installation mistakes.
In this guide, we’ll cover the features, download and installation process, compatibility considerations, and common fixes for ThePancake1 More Traits in CAS. Whether you are installing it for the first time or troubleshooting a problem after a Sims 4 update, you’ll find practical information to help you get the mod working properly.
Quick Answer: What Is thePancake1 More Traits Mod?
ThePancake1 More Traits in CAS is a The Sims 4 mod that expands the number of personality-trait slots available in Create-a-Sim. Young Adults, Adults, and Elders can have up to five traits, Teens can have four, Children three, and Toddlers two. Infants remain at one trait.
The mod is mainly useful for players who want more detailed Sims personalities without replacing the game’s normal trait system. You can use it when creating a new Sim or when editing an existing Sim with supported CAS editing methods.
More Traits in CAS Trait Limits
The extra slots depend on the Sim’s life stage.
| Life stage | Maximum traits with the mod |
| Infant | 1 |
| Toddler | 2 |
| Child | 3 |
| Teen | 4 |
| Young Adult | 5 |
| Adult | 5 |
| Elder | 5 |
These are the trait limits described for the v3a version.
You do not have to fill every slot. If you prefer a Sim with only two or three defining traits, you can leave the remaining spaces unused. The creator specifically notes that additional slots are optional.
Why Players Use More Traits in CAS
The standard trait limit can make character creation feel restrictive, especially when you have a very specific Sim in mind.
For example, imagine you are creating a Sim who is:
- Creative
- Bookworm
- Loner
- Perfectionist
- Vegetarian
With fewer trait slots, you would have to remove some of those characteristics. More Traits in CAS gives you enough room to represent the complete concept.
This is particularly useful for legacy challenges, storytelling, role-playing, fictional characters, family gameplay, and detailed household creation.
The value is not simply having a larger number. The extra slots let you build relationships between traits.
A creative, outgoing Sim tells one story. A creative, outgoing, perfectionist, ambitious, and family-oriented Sim tells a much more specific story.
What Does thePancake1 More Traits Actually Change?
The mod primarily changes the CAS trait interface and underlying trait-slot behavior.
Instead of adding an entirely separate personality system, it extends the existing one.
That means you continue selecting familiar Sims 4 traits through CAS, but you have additional spaces available.
The v3a release also introduced a redesigned trait layout. The creator explained that the previous design could extend beyond the normal CAS area, while the newer layout makes the additional trait slots fit more cleanly.
This makes the mod more useful than a simple numerical change because the interface itself was adjusted to accommodate the additional choices.
What Is New in Version 3a?
Version 3a brought several changes beyond simply increasing the number of slots.
Redesigned trait layout
The trait layout was changed so additional slots fit within the original interface more effectively. This also makes future modifications easier to maintain.
Fixed the expanding panel problem
The creator reported a fix for the personality-trait panel extending beyond the right side of its box when Sims aged up or used a personality potion.
Self Discovery still works
Sims can still gain traits through the game’s Self Discovery system after the mod is installed. The creator explains that the discovered trait appears near the later trait slots.
Custom traits are supported
The mod can work with CC traits, although individual custom traits need to be compatible with current versions of the game.
Does More Traits in CAS Work With Custom Traits?
Yes. Custom-content traits can work with More Traits in CAS. However, there is an important distinction between the mod adding more slots and a custom trait being compatible with the current version of The Sims 4.
Older custom traits can have their own compatibility problems. The CurseForge documentation also warns that older traits affected by past EA changes may need updates from their individual creators.
So if a custom trait disappears or behaves incorrectly, do not automatically assume More Traits in CAS is responsible.
Does the Mod Work With Self Discovery?
Yes.
The game’s Self Discovery system can still give Sims additional traits during gameplay while More Traits in CAS is installed.
This creates an interesting difference between traits you choose and traits your Sim develops.
For example, you might create a Young Adult with:
- Creative
- Bookworm
- Loner
- Perfectionist
- Vegetarian
Later, gameplay can introduce a discoverable trait through the game’s normal system.
This means the mod does not have to make your Sim’s personality completely fixed at the moment you create them.
Can Existing Sims Get More Traits?
Yes, but simply installing the mod does not automatically fill the additional slots for every existing Sim.
The CurseForge documentation explains that existing Sims do not automatically receive the additional traits unless they age up or are manually edited.
For an existing household, players can use supported editing methods such as:
- cas.fulleditmode
- MC Command Center
- Chingyu’s Add Traits Menu
The exact method depends on which tools you already use and whether they are compatible with your current game version.
Can You Have More Than Five Traits?
There is an important nuance here.
The CAS version provides up to five standard personality trait slots for Young Adults and older Sims. However, the game also has discoverable traits that can increase the total number of traits a Sim possesses.
The CurseForge documentation notes that with EA’s Discoverable Traits system, Young Adults and older Sims can technically reach up to eight traits, depending on gameplay and the traits they unlock.
So five is best understood as the maximum number of normal CAS trait slots provided by this mod, not necessarily an absolute limit on every trait a Sim can ever possess.
How to Install thePancake1 More Traits
Installation is simple if you use the correct file.
Download the correct version
Use the current release information from the creator or the current maintainer rather than relying on an old repost.
The original v3a announcement says to download thepancake1_MoreTraitsinCAS_v3a and place it in the Mods folder with Mods enabled.
Put the file in the Mods folder
The usual path is:
Documents
└── Electronic Arts
└── The Sims 4
└── Mods
└── thepancake1_MoreTraitsinCAS_v3a.package
If the download comes as a compressed archive, extract it first.
Enable Mods in The Sims 4
Open the game’s settings and make sure Custom Content and Mods are enabled.
If the game has disabled mods after an update, turn them back on and restart the game.
Test CAS
Create a new Sim and look at the personality-trait section.
For a Young Adult or older Sim, you should see room for up to five traits.
Which Version Should You Download?
This is one of the most important areas to get right because outdated pages can create confusion.
The original thePancake1 v3a announcement was checked against Patch 1.127.41 on August 26, 2026.
A later September 2026 maintenance post from Kallixer states that the same v3a version is compatible with Patch 1.128.90, with the post saying Kallixer has permission and materials from thePancake1 to maintain the mod after thePancake1 stepped back from Sims 4 modding.
This matters because older download pages can still show earlier releases. For example, CurseForge currently lists the older v2d package as its latest file on that platform page, while the creator’s Patreon page contains the newer v3a release information.
The practical rule
Match the mod version to your current Sims 4 patch.
Do not assume that the newest file name you find on a third-party page is automatically the correct one for your game.
What Is the Chingyu-Compatible Version?
There are two versions you may encounter:
- The regular More Traits in CAS version
- The Chingyu-compatible version
The Chingyu-compatible version is not required simply because you use Chingyu custom traits.
The creator specifically says it is intended for players using Chingyu’s More CAS Traits Mod + Long-Lived Traits + Add Traits Menu configuration with the relevant chingyu_MoreTraitsMod_Option_ file.
If you are not using that specific Chingyu setup, the regular version is generally the appropriate choice.
Why Are My Extra Traits Not Staying?
If you select extra traits and they disappear after leaving CAS, there are several possible causes.
You installed the wrong version
This is especially important with the Chingyu-compatible file.
The CurseForge documentation says the compatible version should not be used unless the required Chingyu files are installed. It identifies this as a common reason extra traits fail to remain.
Another mod is conflicting
More Traits in CAS modifies game resources related to the trait interface and aging/trait tuning. Other mods that modify the same resources can conflict with it.
Your game received an update
A Sims 4 patch can change the files that mods rely on.
If the problem started immediately after a patch, check the mod’s current compatibility status before changing your entire Mods folder.
You have duplicate versions
Keeping an old and new version of the same mod together can cause unpredictable behavior.
Remove the old version before installing the new one.
What Files Does More Traits in CAS Conflict With?
The creator identifies conflicts involving:
- traitsmoleculelibrary
- sims.aging.aging_tuning
- Related SimData files
Any other mod that changes the same resources may conflict with More Traits in CAS.
This is particularly important for players who use large collections of UI, trait, aging, or personality mods.
What Happens If You Uninstall It?
You can remove the mod, but understand what happens first.
The current creator documentation says that traits exceeding EA’s default maximum will be removed from affected Sims when the mod is uninstalled.
For example, if a Young Adult has five traits and you remove the mod, the traits beyond the normal game limit may no longer remain.
Before uninstalling
Make a backup of your save.
Then consider which Sims currently depend on the additional slots.
This is especially important in:
- Legacy saves
- Long-running rotational saves
- Storytelling saves
- Large family saves
- Saves containing many customized households
Does More Traits in CAS Add More Lot Traits?
Yes.
This is an unusual part of the mod.
The CurseForge documentation explains that the mod also allows up to five lot traits, because EA connects the CAS and lot trait systems in a way that makes the change affect both.
So installing the mod can affect more than just Sim personality slots.
If you only wanted additional Sim traits, this lot-trait behavior is worth knowing before installation.
Does the Mod Give Pets More Traits?
No.
The current v3a documentation says that pets do not receive additional traits through this mod. The creator also notes that adding pet support may be explored in the future.
So this is primarily a Sim CAS trait-slot mod, not a universal trait expansion for every playable creature.
thePancake1 More Traits vs. More CAS Traits
The names can be confusing because several Sims 4 mods use similar terminology.
More Traits in CAS by thePancake1/MizoreYukii is primarily about expanding the number of CAS trait slots.
Other projects, including Vicky Sims/Chingyu’s More CAS Traits, are separate systems with their own features and compatibility requirements.
| Feature | More Traits in CAS | Custom Trait Mod |
| Adds CAS slots | Yes | Usually no |
| Adds new trait choices | Not its main purpose | Yes |
| Supports CC traits | Yes | Depends on the trait |
| Main use | More personality slots | More personality options |
| Compatibility concerns | UI/trait resources | Depends on individual mod |
Understanding this difference can save you from installing several mods that attempt to solve the same problem.
Best Ways to Use the Extra Trait Slots
More slots are most useful when each trait contributes something meaningful to the character.
Create stronger character concepts
Instead of choosing five random traits, start with the character’s main identity.
For example:
The ambitious artist
- Creative
- Perfectionist
- Ambitious
- Loner
- Art-related CC trait
The combination gives the Sim a clear personality instead of five unrelated labels.
Build realistic families
Give family members traits that explain why they get along—or why they clash.
A parent could be Family-Oriented and Neat, while their teenager is Creative, Loner, Goofball, and Noncommittal.
Make fictional characters more recognizable
If you recreate a character from a book, television series, or game, five slots give you more room to represent different sides of their personality.
Support legacy storytelling
Extra traits can help distinguish generations instead of repeating the same few personality choices.
A Simple Trait-Selection Formula
If you are unsure how to choose five traits, use this framework:
Choose one core identity trait
Ask:
What defines this Sim most?
Examples include Creative, Genius, Ambitious, Good, or Active.
Add one social trait
Ask:
How does this Sim behave around other people?
This might be Outgoing, Loner, Self-Assured, or another suitable trait.
Add one interest or lifestyle trait
Ask:
What does this Sim enjoy?
Consider hobbies, food preferences, animals, or outdoor interests.
Add one strength
Ask:
What makes this Sim successful?
Perfectionism, ambition, confidence, or another suitable characteristic can fill this role.
Add one source of conflict
Ask:
What makes this Sim imperfect?
A contrasting trait can create more interesting gameplay than five traits that all point in the same direction.
Common Problems and Their Fixes
| Problem | Likely reason | What to check |
| Extra slots do not appear | Mod not loaded | Mods settings and file location |
| Traits disappear after CAS | Conflict or wrong version | Conflicting mods and compatibility |
| Game behaves strangely after update | Outdated mod | Current patch status |
| Chingyu version fails | Missing required Chingyu files | Use regular version if appropriate |
| Custom trait is broken | Old CC trait | Update the individual trait |
| Extra traits vanish after uninstall | Expected behavior | Restore backup if necessary |
| Panel looks unusual | Visual/UI conflict | Other CAS and UI mods |
Common Misconceptions
You have to choose five traits
No. The additional slots are optional. You can leave them empty.
Five traits is the absolute maximum possible
Not necessarily. The game’s Self Discovery system can provide additional traits during gameplay, meaning the total number of traits a Sim can possess can exceed the standard CAS slots.
The Chingyu-compatible version is required for Chingyu CC traits
No. The creator specifically distinguishes between ordinary Chingyu CC traits and the particular Chingyu mod configuration that requires the compatibility version.
The mod gives pets extra traits
No. Pet trait expansion is not currently included.
Every old download page has the latest version
No. Current search results show older v2d files on CurseForge, while the creator’s v3a release is documented separately. Always check the version against your game patch.

Conclusion
ThePancake1 More Traits in CAS is useful for Sims 4 players who want more control over personality without completely changing how traits work. Its main purpose is simple: expand the number of CAS trait slots so your Sims can represent more detailed characters.
The current v3a system provides five traits for Young Adults and older Sims, four for Teens, three for Children, and two for Toddlers. It also supports custom traits and continues to work with Self Discovery.
The most important part of using the mod successfully is version matching. Because Sims 4 updates can affect mods, check the current maintenance status before installing or updating. As of September 2026, the maintained v3a release is reported compatible with Patch 1.128.90.
If you want Sims with deeper personalities, more specific character concepts, and greater freedom in CAS, the extra trait slots can make a noticeable difference in how you build and play your households.
