Don’t get me wrong. Like anyone, I love the soft blue/green/white gradient of TS4’s CAS configuration.
Sometimes, the background can become monotonous and boring.
It is especially true if you are a Simmer who spends hours making Sims rather than actually playing them.
While I am more of an “explore the entire game” girl, I know friends who are masters at creating beautiful Sims. If your CAS feels a bit dull, don’t worry.
This list is so long, that I have divided it into three categories: Scenes & Backdrops and Colors & Patterns. Enjoy!
Colors & Patterns
It’s very simple.
These CAS backgrounds have simple colors and designs. They don’t depict any type of scene (e.g., a street scene or a building).
1. Luumia CAS Overhaul 2
Let’s begin with something simple and clean.
Luumia’s 2nd CAS Overhaul offers great alternatives to the Sims 4 default setup.
Apart from the immersive lighting that gives Sims more depth and an eye-spray remover for pets, you can also choose the color of your background CAS: there are 5 pastel gradients and 7 solid colors.
It’s perfect for those who don’t want any fuss or hassle and aren’t looking for frills. The solid white background is my preference, as it makes each Sim’s color pop.
2. Snow Kimx’s Cute CA
This CAS BG is so similar to the wallpaper in a spacey, star-loving child’s bedroom. I love it.
The stars and planets doodled on a soft background with cotton-candy clouds outlined by chalk?
It’s just too adorable. It’s so cute!
3. Busra-tr’s Rainbow
SnowKimx’s BG was designed for kids who are obsessed with planets and stars, but busra-tr’s Rainbow CASBackground will suit the more artistic child who enjoys fingerpainting or hand-printing.
This full-screen display of rainbow splotches is psychedelic and has the touch of a multi-colored lava lamp.
That is what I mean.
4. Kat Verse CC’s Stars n Colors
KatVerseCC’s Stars n Colors CAS Background is a good mix of “unicorn drinks colors” and “actual sparks.”
This combination is amazing!
Although I did not, it is clear that the creator was a visionary.
Although it isn’t as wall papery as the other two, it’s just as enjoyable.
5. KatVerse’s Striped Studio CA
Wallpaper territory is back, but it’s hard to believe that we’re still here.
This wallpaper is adorable!
Simple, candy-colored stripes create a stunning backdrop for all your beautiful and unique Sims.
You can also choose from eight different colors if you want to change it up. My favorite colors are purple and mint.
6. UrbanSims’s Fall Backgrounds for CAS
The link will take you to a page with several CAS background colors packs.
The pack I chose was the creator’s Fall Backgrounds pack.
If golden, earthy, and warm tones don’t suit your style, I recommend checking out the other packs.
FYI, I also tried the Urban Pastel CAS Backgrounds Pack. Your bubblegum is pink.
7. Background for KatVerse’s Camo CA Background
We were introduced to the Military career through the StrangerVille pack.
Why not create a soldier with a matching background?
Another one of KatVerse’s original creations is this unique camo-print background CAS background.
This might not be for everyone, especially if your Sim is fond of using a lot of greens and browns. But it’s worth knowing that lighter colors work well. A definite plus.
8. KatVerseCC’s Marble CA Background
This blue-white-grey marble background is no exception.
This is because I am obsessed with water themes, and water patterns, and I had to include them.
It is all artistic ripples and watery streaks. It makes me think about a large floor-to-ceiling oil painting in a high-end art gallery my Sims would visit when they go on vacation.
It’s my favorite thing about it and I hope you do, too.
9. KatVerseCC’s Grey Grunge CAS Background
This one has that photo-studio-backdrop feel to it that I think is pretty fun.
It would be great to download custom CAS poses for Sims.
Particularly if your Sim likes the grunge-y street style, casually urban.
10. KatVerse’s Colorful Gradient
I offer a middle ground, a gradient if the rainbow splotches of item number 3 are too bright and defined and the solid colors of number 1 too flat.
Three gradients are specifically available from KatVerse.
The third option, which is a lovely soft mix of blues and purple, was the one I tried. It is absolutely gorgeous!
This soft color wash can also be achieved by zooming in on your Sim.
11. KatVerseCC’s Wooden Floor Background CAS Background WF01
This one feels a lot like the grunge background but less “artfully scuffed.”
A wooden floor is also available.
This one is simple, and I appreciate it.
It has a “performing arts” vibe.
Your Sim looks great standing on the ground, and the spotlights above give it the illusion of being on a stage.
Zooming in does not pixelate the texture, which I find to be quite amazing.
12. KatVerseCC’s Stars Background CAS
This one is very similar to a backdrop for a prom photoshoot but in the most beautiful way.
I find darker colours can get lost in the black background, but it doesn’t bother me.
It’s not when my Sims are standing in front of a backdrop so beautiful and classy.
Zooming in blurs the stars, but it is still quite artful.
As if you had taken a star brush in Photoshop and swiped it across your top.
Scenes & Backdrops
These backgrounds are created using images of scenery and reflect a real physical setting.
These photos look almost like landscape photos that your Sim can stand in front of.
Common themes include nature-y backgrounds, such as parks, trees, forests, and modern urban settings, like buildings, interiors of housing, or commercial backdrops.
13. The Amazing Landscape of Nowa2000
This fantasy world background pack by Nowa2000 is what we need to get started.
This set includes 10 backgrounds from CAS that depict futuristic and fantastical worlds.
The third option, for instance, has some alien-looking plants in the background. While the second looks like it’s a spaceship full of honest-to-goodness,
This pack was fantastical, and I enjoyed it immensely. I am a self-proclaimed fantasy geek.
Option seven is my favorite, as I love ruins.
14. KatVerse’s Forgotten Grotto (HL04)
This CAS background from KatVerse (again) is yet another perfect Maxis-Match-masterpiece.
All Sims 4 elements, including the crystals and rocks, have the same clayified feel.
It is one of the most immersive backgrounds available on the list. It looks almost like your Sim wandered into a forbidden grotto to take photos.
15. KatVerse’s Winter Wonderland
I accept the cultural influence that Frozen had on my generation.
It’s so potent, every winter/snow/ice-themed thing has me (and many others) thinking of Disney’s Queen Elsa and her iconic musical belting.
This Winter Wonderland CAS BG Pack is no exception.
No, I do not want to make a snowman.
There is also a background option that uses CAS to show a snowman (cuddling up in jolly ol’ Saint Nick).
16. KatVerse CC’s Enchanted Forest
Why is this background not under the Pop Culture Scenes section of the website?
Although the creator may have used her Merida SIM as a feature photograph, she never claimed this to be the Highland forest of Brave fame.
It could be used as a generic enchanted forest that you can use to house your Sims. It also photographs beautifully.
Some great shots were taken by my redheaded Sim.
17. Little Dica’s Old School, CAS Room
Now for something more true-to-current-life; an old schoolroom setting.
This is a simple idea that I believe was well executed.
The objects in the background, just like the Forgotten Grotto item, have a clayified Maxis Match texture, which gives them depth and dimension.
It looks more like a printed backdrop photo, but it’s still in the game.
Six styles are available, and the creator even included a re-color kit!
18. Thorben.maerz TS2 Inspired T4 BG
What about a little bit of nostalgia? Do you remember the TS2 CAS setup?
This red-brick room has a mirror, window, and wall decor.
Sims creator thorben.maerz recreated the exact same room using Sims 4 textures and objects.
They made it into a sweet TS4 CA BG for newer Simmers.
You have to love the shadow and light detail. It makes it appear highly interactive.
19. Annett’s CAS Backgrounds “Room” Part 2
Similar to the previous item, the Annett CAS Backgrounds “Room” pack (part 2) reminds me of The Sims’ CAS setup.
Perhaps it is the mirror. Perhaps it is the window. Perhaps it’s the angle.
It could be all three.
I don’t know much, but I was smacked hard by nostalgia when I saw the sample images.
This set comes in three design/color options. The mauve-y, brown one was my favorite.
20. Annett’s CAS Backgrounds, “Town Streets”.
The Town Streets CASBG pack includes some loud pieces.
These are all elements that can be found in backdrops.
This is not the right setting for people who want a more minimalistic, cleaner environment when creating Sims.
For those who like pictures that convey a rush, movement, or activity,
These backgrounds are perfect.
You have seven options for choosing from. Background 5’s sepia-old-timey vibe appealed to me.
21. Annett’s CAS Backgrounds, “White Room” Part 1
For a quick break, I bring you another Annett CAS backgrounds pack.
This piece is muted and quieter than the last one in the sense that there are a lot of white rooms.
Just because, your Sim is taking pictures in some (almost frighteningly) sterile white rooms.
Personally, I think that the lighting and shadows in this background make it look amazing.
22. Arch’s Custom Backgrounds for CAS
You can use this flat mesh by Arch to place screenshots onto it to create custom-made CAS backgrounds.
These options are very similar to the Annett CAS BG packs. The main difference is the texture. Annett’s CAS backgrounds are akin to photo backdrops in a studio.
These backgrounds have a nice clayified texture, which makes CAS screenshots appear like they were taken in-game. This is a feature that I love.
23. Annett’s CAS Backgrounds Autumn ’17
We’re back outside.
This Autumn 2017 CAS BG Pack is stunning. But that could also reflect my undusted love for Fall colors.
This pack offers a lot of options. There are nine options in this pack.
They’re all filled with different shades of red, orange, and gold.
Although the backgrounds are not Maxis Match, they look quite immersive due to the way some of them have been lit and shadowed – particularly backgrounds 1 and 7.
24. Frau Engel: Annett’s House, “Autumn Wood”
We might want to have a magical forest with a lot of Fall backdrops. So why not have a cozy, holiday-themed cabin in the woods?
This ten-piece background pack for CAS is as quirky and unique as it gets.
The objects have great detail and depth that makes them appear three-dimensional.
Although not exactly clayified, it is still not completely green-screen-esque.
25. Annett’s Christmas Eve by Frau Eng
Now that you have seen the outside, let’s get inside.
Although it is not explicitly stated that this is the interior of the Autumn log cabin, the narrative works well.
It can even be made by the same person!
This Christmas Eve pack shows the inside of a cozy and homey wooden house decorated with Christmas decor.
There are nine variations, each showcasing a different area of the mysteriously festive home.
The hallway, the kitchen, and the child’s room are all there. It’s all beautiful.
26. The CAS Background Set “Jungle”, by Nowa2000
The Sims 3 World Adventures was my favorite game when it first came out.
I spent hundreds of thousands of hours and probably hundreds of thousands more Simoleons painstakingly navigating through the various pyramids, tombs, and booby-trapped Champs Les Sims manors.
Now, don’t get me wrong; The Sims 4: Jungle Adventure is a pretty cool explore-the-wilderness pack too.
It was the chaos, local shenanigans, and lack of limits in World Adventures that made it irreplaceable.
Seeing this set of seven CAS Jungle backgrounds reminds me of the chaotically random expansion pack.
These backgrounds are adventure-themed and I recommend them highly.
27. The CAS Background Temple at Nowa2000
Do you know which tomb I conquered first in TS3 World Adventures TS3 World Adventures? The Dragon’s Maw.
That’s what I meant. But I could be wrong.
The stunning background of Temple CAS from Nowa2000 is very reminiscent of the tomb. You’ll be amazed at the size of the room, with its yoga mats and fire traps.
Just like the Jungle Pack, I also had to download the BG and test it.
10/10 I would allow my Sims to shamelessly pose in this background for the rest of their natural simulated life.
28. Nowa2000’s Wasteland CAS Backgrounds
We are now back in urban/industrial territory with the Wasteland CA BG pack, still available at Nowa2000
This pack was not included in the original background of this creator. I had to struggle a little with it.
Let me be real, some background variations were too pixelated. This is especially true when you zoom in.
The backgrounds had a strange, two-dimensional feel (especially #3 and #2), which really supported the “green-screened background narrative.”
I was eventually won over by the concept and background #2, which is quite shocking.
It’s a cool set of landscapes that have been abandoned and are now ruined. This adds a lot to your game.
29. Annett’s CAS Backgrounds “Graffiti”
These are some very noisy backgrounds for CAS.
They look really cool.
Six stunning backdrops for your urban, street-smart Sim. The backdrops are also of high quality.
There is not a lot of pixelation if you zoom in-I zoomed all the way into the face area, mind – but plenty of ambience to give each variation a unique atmosphere.
30. Annett’s “Bathrooms – Part 2”
These are completely different from the previous items, but I felt we needed to take a break.
Is it really possible for Sims to pose in bathrooms? Evidently so.
I can see the appeal. The bathroom backdrops included in this set are beautiful and chic.
#3 was my favorite (the combination of earthen and marble tones really spoke to me), and #8 (just look at the knobs in the shower!
Sometimes, you just want your Sim to be wealthy and luxurious. These bathrooms look absolutely gorgeous to me.
(Except #2. It almost looks like a communal… space. The rest of the rooms are great!
31. Annett’s “Dressing Room”
Do you think dressing in a dressing area is infinitely more enjoyable than in a bathroom?
It would be my opinion. It’s up to you to decide, but I thought my Sims looked and felt much more classy in front of the CAS backgrounds.
See? They were in towels and robes.
It was difficult to choose a favorite from this assortment. Literally, all of the dressing rooms in this pack are stunning!
There was no one variant that was not overshadowed by the lighting and shadows, the layout, and the oh-so-luxurious elements.
You will have no trouble choosing and installing one.
32. Heaven and Hell Backgrounds for Nowa2000 CAS Backgrounds
Hey. If we can have futuristic/post-apocalyptic wastelands, overgrown jungle ruins, and straight-up luxury bathrooms for TS4 CAS… we can definitely throw in some divine flavors, too.
This Heaven and Hell CASBG pack by Nowa2000 has some stunning backgrounds.
It’s more than just “clouds and lights versus brimstone & fire.”
You can find actual variations on each plane, I swear.
There are two versions of the Heaven background: one with steps in the back and one that has…what appears to be a Greco Roman temple?
There are four versions of the Hell background, each with a distinct mix of fire, ash, and rubble.
Do you know how I managed to sneak some wings in there too?
33. Kat Verse’s Realm of Magic Backgrounds
This is one of my favorite TS4 game packs so I was excited to get it.
It’s a good thing I did because the graphics are excellent. They are absolutely stunning.
My usual red-haired Sim was able to quasi-cosplay Sabrina, the Teenage Witch (Archie Comics Version). She posed in front of the Magic Realm portal. I loved it.
This pack contains five background options, all of which are beautifully designed. Personally, I love the ones that have the portal from the Magic Realm or the portal from Glimmerbrook.
34. KatVerse’s Sulani Backgrounds CAS Backgrounds
This Sulani CASBG pack from KatVerse will make your Sim look half-Sim and half-fish, no matter what stage they are in.
These scenes show the beauty and elegance of Sulani in-game.
Two sunny options are available for sun-kissed Sims, and one “starry evening by the sea” option is available for those who prefer a romantic setting.
35. KatVerse’s Sylvan Glades HL02
Lastly, a CAS background straight out of one of the TS4 Hidden Worlds.
Actually, the correct terms are “a secret lot” and “hidden area”, but Hidden World suits my dramatic fantasy nerd self more.
The Sylvan Glades can only be accessed via the Sylvan Tree, which is located next to Willow Creek’s Crick Cabana lot.
Although I think it’s a terrible thing that you can’t do much there, other than wandering around and fishing, I still love the beautiful graphics.
They also translate well into a background in CAS.
36. KatVerse’s Sabrina Background
Speaking of Sabrina the Teenage Witch…
What can I say? Growing up, I was a huge fan of comics.
It’s also a simple background with the silhouette of an iconic character.
It’s a unique concept and the quality is excellent. There is nothing to be unhappy about.
It makes for an interesting and novel CAS experience.
37. Kat Verse’s Disney D02 Background
I am trying to think of a clever Agrabah/Aladdin/Sims 4 connection but I have no idea.
Remaking the Agrabah market and Royal Palace into a Sims 4 CAS background is genius.
This background is not necessary if you have a deep love for Disney classics. It’s not.
These reasons were enough for me. I was immediately impressed by the sample photo and clicked the Download button.
(And I may have also tried to put my Sims in Aladdin-inspired costumes. We won’t know.)
38. KatVerse’s The Vampire Diaries Background
Although I have never seen an episode of Vampire Diaries, I can recognize the Salvatore Boarding House.
This is a great background for your Vampire Sim to pose in front of if you are a fan.
Even if you aren’t, it’s still a charming backdrop. It’s also of high quality.
Zooming in does not pixelate the image.
39. KatVerse CC’s Alice in Wonderland Background CAS
Alice in Wonderland is such an iconic and charming piece of pop culture, that I was not surprised to see a background from CAS.
This is a very artistic piece, especially because the creator uses easily-recognized Wonderland elements without making it look sloppy or too cluttered.
The creepy grin of the Cheshire Cat, the Red Hearts background, and the giant flowers with faces (which I chose as my Sim photo op background) all evoke Alice in Wonderland without being actual screenshots.
These backgrounds are great if you love the story, world, or just the style.
40. Joyzilla’s World of Warcraft Background Set
Here’s the final part of our CAS background pack.
I offer you World of Warcraft Sims 4 Edition.
It’s not really… but you have to admit that the amount of detail in each scene is absolutely stunning.
There are 10 backgrounds available, all of which are stunning. It’s all on point.
There is a variation to suit every mood, I think.
Happy field of flowers? Check.
Mysterious ruins? Yep.
A simple, yet enchanting and foreboding flower coven. Gotchya covered.
Each version has its own download link. You can also clearly see the various backgrounds in the featured photos.
To get a feel for each scene, I tried #8 and #10 and can confirm that both the quality and detail are excellent.
There is no pixelation here. Give them a shot and let us know what you think.
