Since its release in late 2014, The Sims 4 has amassed a whopping thirty-six million players, with ten million of them actively tuning in to the game every month. Its massive, dedicated fanbase constantly strives to improve the game, even if they have to do it themselves in the form of mods.

As an essential part of EA's life sim, mods allow Sims players to customize their gameplay and fill in the empty spaces left by the game's more basic version. These fanmade add-ons are also instrumental when creating Sims with unique features and personalities that make them stand out amongst the rest.

Updated On January 10, 2024 by Hannah Grimes: There are always new, creative mods coming out for The Sims 4 that enhance sims' appearances and help improve the already addictive base game where it's lacking. This list has been updated to include a few more options, as well as fit updated CBR standards.

15 The MC Command Center Gives Greater Control Of The Sims 4, Including CAS

• Best Sims 4 CAS Mod For Overall Customization: MC Command Center by Deaderpool

The MC Command Center mod for The Sims 4, created by Deaderpool, gives players more customizability when it comes to every aspect of the game. This includes extra options for cleaning up or diversifying towns, a dresser option for modifying clothing and outfit choices, and more customization inside of Create-A-Sim.

When it comes to CAS specifically, the MC Command Center allows for greater control over character customization. Players can change the size and appearance of individual body parts, as well as alter very small preferences of their Sims, like their favorite drinks.

14 Making Sims Stylish With Custom Content

• Best Sims 4 CAS Mod Resources: The Sims Resource, Maxis Match CC World

It's no secret that the Sims 4 isn't the best fashion-wise, and while the hairstyles in the game are far more diverse than in the previous versions, all players could do with more variety to choose from. The talented modders from the Sims community are constantly bringing the latest fashion trends to the Sims 4 in the form of Custom Content.

There are many sites to browse for new clothes, hair, and accessories, but The Sims Resource and various Tumblr pages like Maxis Match CC World are the most popular and best organized of the bunch. In the last few years, the Sims team has done some work to diversify the game's catalog, but modders are clearly still winning when it comes to style. While there are mods for other parts of the game, too, Sims 4 CAS mods remain the most prevalent and popular to this day.

13 Letting Sims Express Themselves With Custom Tattoos

• BestSims 4 CAS Mod Tattoos Include: Space tattoos, Formal tattoos, Finger tattoos

Getting a tattoo is a big life commitment most of the time, but Sims have the advantage of interchanging them with a few clicks. While The Sims 4 already comes pre-packaged with a few tattoo designs, modders have created even better and more unique patterns to fit every Sim's lifestyle.

Whether they want to be fully inked or get a simple design that is easy to hide, every Sim can benefit from trying out one of the many Custom Sims 4 CAS Tattoo Mods floating around the internet. With these skin details, players can create Sims who either love showing off their ink or prefer to keep it hidden.

12 Making Sims' Eyes Stand Out With 3D Lashes

• Best Sims 4 CAS Mod for Eyelashes: 3D Lashes by Kijiko
• Best Sims 4 CAS Mod For Removing Base Game Eyelashes: EA Eyelashes Remover by SadnessSimmer

The blocky, shapeless eyelashes in the Sims 4 are not exactly a favorite among beauty-inclined fans. Thankfully, there are several mods that remedy this issue. Kijiko's 3D Lashes has become the standard for players looking for new lashes at this point. Most dedicated Simmers use the mod and are quick to recommend it as the best option to replace EA's eyelashes.

Once added to the game, Kijiko's 3D Lashes can be found in the glasses section in CAS and can be applied to teens, adults, and elder Sims. Additionally, SadnessSimmer's EA Eyelashes Remover Mod will get rid of the game's original eyelashes, so the player will have a better canvas for their own CC.

11 Add Columns To Filter Through CAS Content More Easily

• Best Sims 4 CAS Mod For Adding More Columns: More Columns In CAS By weerbesu

Scrolling through everything that Sims 4's Create A Sim has to offer can take a while, and the time it takes to scroll through the gallery only increases as players install more custom content. Thankfully, the community solved this potential problem by creating mods that add extra rows to Create A Sim, allowing players to view all their content more easily.

The best mod in this regard is weerbesu's More Columns In CAS mod, and it comes in three different flavors. Players can choose whether to use three, four, or five rows while browsing through CAS in The Sims 4.

10 Applying Preset Features

• Alternate Sims 4 CAS Mod Preset Options: Alternate mouths, alternate jaws, and alternate noses

When struggling to create the perfect Sim, it's always better to first try the preset features in CAS and go from there. The Sims 4 already provides several pre-made mouths, eye-shapes, and noses, but the Sims community has many more to offer. There are tons of Sims 4 CAS Mods that add extra preset options that are typically far more appealing than the game's base gallery.

From the popular full mouths and sharp jaws to the array of big and small noses, modders have options for any kind of Sim the player has in mind. Once in the game, they'll appear next to EA's presets and can be edited accordingly with the game's handy click-and-drag mechanic.

9 More Diverse Bodies With The Expanded Physique Range Mod

• Best Sims 4 CAS Mod For Body Diversity: Expanded Physique Range by df1112

The click-and-drag feature used to customize Sims' bodies in CAS is one of The Sims 4's best additions to the franchise. It allows Simmers to fully change their character's body type, letting them widen or narrow shoulders, extremities, and torsos, and even change the size of their feet.

Some modders took this even further. The Expanded Physique Range mod on the popular ModTheSims site takes this mechanic to even bigger extremes, allowing for even more diverse bodies. It goes up to ten times over the limits of the game and works will all ages except children and toddlers.

8 Organize Custom Content Easily With Tidy Details And Tidy Tattoos

• Best Sims 4 CAS Mod for organizing content: Tidy Details & Tidy Tattoos by sparrowcc

In addition to mods that grant extra rows to CAS, there are other community-made tools to help players sort through all of their content more easily. One of the best is called Tidy Details & Tidy Tattoos by sparrowcc, which labels individual items to show players which space they're taking up on their Sim by using certain customization options.

While this seems self-explanatory, this isn't always obvious, especially when it comes to mods. Items conflict with each other all the time, causing others to break, and these labels allow for easier sorting to better keep track of which CAS details apply where.

7 Bringing Back The Iconic Color Wheel From The Sims 3

• Best Sims 4 CAS Mod For Changing Colors: Color Slider by thepancake1 and MizoreYukii

Sims 3 players fondly remember the Color Wheel as one of the best features of the game. It allowed for a wide variety of colorful combinations and patterns for hair, clothes, and even furniture that the Sims 4 is still missing almost a decade after its release. Thanks to Sims 4 CAS Mods, the iconic Color Wheel that fans love has been added back to the franchise.

Seeing this blank spot in the game, Simmers thepancake1 and MizoreYukii have developed an effective Color Slider mod for The Sims 4. This add-on feature works with hair, clothes, accessories, and even medical wearables to give Sims that perfect splash of color the player has in mind.

6 Height Sliders Help Diversify The Sim Population

• Best Sims 4 CAS Mod for Diversifying Height: Height Sliders by Luumiasims

The Sims 4 currently only has four different heights: infant, toddler, children, and teen to elder. In previous games, teens were slightly shorter, which made them much easier to identify. This was changed in The Sims 4, instead making teenagers the same height as adults, but Sims 4 CAS mods change this for the better.

With Height Sliders, Sims can now truly simulate real life and appear to be taller or shorter than the game's usual standard for each life stage. This mod isn't perfect, and some clipping and animation errors may occur when installed, but it's a nice option for small height alterations and impressive for something fanmade.

5 Preview How Sims Look In Various Settings With Alternate Lighting Effects

• Best Sims 4 CAS Mod For Previewing Different Lighting: CAS Lighting by simplyanjuta

The lighting in The Sims 4's Create A Sim mode isn't the only lighting available in-game, so it's not an accurate depiction of what players' Sims will look like in different situations. The modding community's answer to this is mods that change the lighting inside of CAS, with simplyanjuta's CAS Lighting mod containing four alternate lighting modes.

Aside from the default Sims 4 lighting, this mod includes Citylight, Citylight Torchlight, Neutral Light, and Neutral Light Torchlight. These particular lighting effects are meant to be spooky-themed as they were released around Halloween, but there are a ton of other options out there as well.

4 Using Skin Details To Make One-Of-A-Kind Sims

• Best Sims 4 CAS Mod For Skin Details: Vitiligo Mod by Peachtrees and Teenager Acne Mod by sorokacc

While the Sims team has finally listened to feedback and included more skin tones and details, there are still a few that modders have continued to perfect the finer details over the years. Peachtrees has a great mod for those looking for vitiligo options, and sorokacc provides a more realistic mod for teenage sims that gives them acne.

Whether it's a Sim with freckles, a scar, or pronounced eye bags, there's a skin detail mod for them. Beautifying skin overlays mostly contour and highlight the face, and can completely change a Sim's appearance. Experimenting with these mods might create an even better Sim than intended.

3 Giving A Touch Of Realism With A Facial Asymmetry Slider

• Best Sims 4 CAS Mod For Face Realism: Facial Asymmetry Slider by Luumiasims

Contrary to what The Sims 4 would have players believe, people are not completely symmetrical. A handy Facial Asymmetry Slider can help bring that last touch of realism to any Sim. This is one of the best Sims 4 CAS mods that provide players with more realism in their character creation.

With this mod, morphing the face so both sides won't be the exact same is as easy as dragging on the top of the Sim's head slightly. Features can be skewed in the center of the face like the eyes, the nose, and the mouth until the player is happy with the end result. Now Simmers can make their characters stand out amongst the perfect, doll-like Sims.

2 Alternate GShade Presets Completely Change The Game

• Best Sims 4 CAS Mod For Gshade Presets: moonivy's gshade preset

Tons of mods change how Sims or the world they interact with look, but nothing changes the game like alternate GShade presets. These presets completely change the way details look in The Sims 4, letting players completely stylize their game experience in the same vein as Minecraft shaders.

Although there are many fantastic options, moonivy's GShade preset is particularly eye-catching, as it doesn't even look like The Sims 4 anymore. There are two different versions, one with a softer and more emphasized outline, depending on preference.

1 Making Sims Unique With Custom Traits

• Additional Sims 4 CAS Modded Traits include: Activist, Loser, Handy Helper

Once the Sim is looking great and ready, it's time to truly make them one-of-a-kind by assigning them some traits. Except, the traits in the Sims 4 aren't as varied as they could be, and all Sims end up acting the same, doing random push-ups on the side of the road even if they're meant to hate exercise, and so on.

In comparison to The Sims 3's massive catalog of ninety-nine traits, The Sims 4 barely has fifty-six despite having over thirty DLC packs. As per usual, modders have come to the rescue with a variety of general and specific traits like Agoraphobia, Bossy, Compassionate, and many more that will completely revitalize the game and produce more unique Sims.
