Sims 4 CAS Backgrounds CC & Mods
Sims 4 CAS Backgrounds

You might have noticed that the Sims 4 default background is quite boring and outdated. As fun as the game is, the background is the complete opposite of it, and we wouldn’t want you to continue playing with these default settings. So we’ve found the best Sims 4 CAS background for you, so that your game can become more lively and vibrant. You can switch between these backgrounds, so no fear of getting bored of looking at the same thing for years. 

There’s a wide variety of these BGs, such as floral, old school, bedroom background, and many more. So you can choose the ones that vibe with your style. 

Sims 4 CAS Background

This article is all about the variety of CAS background Sims 4, but before we jump to that, it’s vital to know how to install these backgrounds, so that you can easily use them. 

The download links would be given below, and once you download the files from there, open them in the downloads folder as well as the mods folder simultaneously. 

To go to the mods folder: documents > electronic arts > sims 4 > mods, here you can put in any cc or mod that you download. So drag the CAS background that you’ve downloaded in the mods folder and restart your game. 

Note: Download only one Create A Sim Background at a time, so that the system doesn’t get confused about which BG you want. Also, enable the mods in your game settings before you do this. 

A Mod Required Before You Use CAS BG

So there’s a mod that you might have to use when you’re using a CAS background, and that is the “blob remover mod.” If you notice a blue bob under your sim’s feet while using the CAS background, then it might be a glitch and you’d need the blob remover mod to get rid of it. 

List of CAS Background CC

Let’s take a look at all the backgrounds that the CC creators have created to avoid dull backdrops. 

1. Starlight CAS Background

Starlight CAS Background

So number 1 CAS background mod on our list is Starlight. It’s a beam of light that originates from your sim’s calf and spreads into pink, magenta, orange and yellow colours against a sparkly black backdrop. Your sim’s would be the centre of attention with this BG.

2. Vejle Harbour Denmark

Vejle Harbour Denmark

This background is inspired by a real life location, and it displays your sim standing at a boardwalk surrounded by water and boats. There are beautiful buildings and all of it is aesthetically pleasing. You sim’s appearance can also be enhanced with this backdrop.

3. Large Room CAS Background

Large Room CAS Background

If compared with others, this BG is quite basic with a combination of white, black and grey colours. However, it makes the other colours pop and makes you appreciate your sim’s clothes, and other items that you wouldn’t have in a normal EA background.

4. Graffiti Wall CAS Background

Graffiti Wall CAS

For those who want a bold and loud background, then this is the right choice. Your sim’s would look really cool with these graffiti walls as backgrounds, which shows their wild side. Is this the TS4 CAS background for you?

This background is perfect for those who are more into a minimalist approach, and want their sims to be in the limelight.

6. Alice in Wonderland

Alice in Wonderland

All literature fanatics, this background is for you. This Alice in Wonderland Cheshire Cat BG with a cat’s face staring at you, is quite cool and dominating at the same time. With this BG, you can even experiment with your sims and create them uniquely to uphold the spirit of the background.

This collection of Create A Sim backgrounds are one of my favorites because of its aesthetic qualities.

10. Wooden Floor

Wooden Floor

As the name suggests, this background has a nice grunge look with plain grey walls and wooden flooring. Also, the lighting of the room puts your sim as the centre of attention. Moreover, a BG with a floor looks more realistic instead of your sim just floating in the air.

11. Bathroom BG

Bathroom BG

Some people might not understand the significance of a bathroom background, but trust me, it’s a must! When getting dressed everyday, it’s important to have a BG with modern, floral glass walls that enhance your sim’s beauty as well. Now who wouldn;t want to get ready in such a gorgeous setting?

This would help them look at the finer details of their sim’s appearance, and all your sim’s clothes would pop against this background.

13. Bedroom Part 1

Bedroom Part 1

A background that allows you to feel as if you’re in your own home is the best part. It’s a much better option rather than looking at a green and blue bubble while your sim gets ready. There’s a huge closet as well in the background, making it more realistic and fun.

14. Black Background

Black Background

Like the white backdrop, this black background works in the same way. Infact with a black CAS background solid colour, your sim’s clothes would have a better chance of demanding attention. The brighter the clothes, the more pop they’d have against this backdrop.

Pink Clouds

53. Striped Studio

62. Room Part 2

Room Part 2

The first part of this background mod didn’t offer as much as this one does. You can get beautiful curtains with matching rugs, and this is a CAS background with mirror. It’d feel like you’re in a real life changing room, and who doesn’t want that?

63. Alice


Don’t confuse this BG with Alice in Wonderland. This backdrop features splotches of different colours in the background with leaf or line patterns on them. It’s one of the most gorgeous backgrounds you might have seen. 

64. The Sims 2 Inspired BG
