With its serene hues of blues and greens, it captures the essence of an underwater paradise, creating a dreamy backdrop for your mermaid Create-A-Sim (CAS) sessions.
When I downloaded and added this CAS Background to my game I was surrounded by tranquil beauty and realistic aquatic scenes. I found this background to be ideal for fans of the fantastical and those who wish to add a splash of magic to their Sims’ lives.

Brush up on your Sims’ musical talent with ‘The Recording Studio Sims 4 CAS Background’ by PureRadianceSim.
Designed for vocal artists at heart, this background features a sleek, dark recording studio vibe. I loved it when I downloaded and installed this mod in CAS. I found the high-tech mixing board, a cozy lava lamp, and essential recording gear to be a perfect CAS background setup for my Sims dream music career.
They’ll feel the thrill of recording their first hit, surrounded by the tools of the trade in this professional studio atmosphere. It’s where musical dreams meet reality, setting the stage for your Sims’ rise to fame.
3. Catwalk CAS Background by Noridca-Sims
This Cawalk CAS Background by Nordica-sims is another favorite of mine. It’s frankly the perfect modeling background in CAS!
This background features a sleek modern catwalk, complete with spotlights and a runway.
Try it out in CAS and let me know what you think. Your Sims will look like they’re ready to show off their latest apparel on the runway.
Note: for CAS background changes you will need to first download a blob remover so you don’t have a blue blob where your sim is standing.
4. Old School Sims 4 CAS Background with Mirror by littledica
This is called the Sims 4 Old School CAS Background, maxis match, for a reason. It’s meant to give you those Sims 2 and Sims 3 CAS vibes where we made our Sims in a random room featuring a very prominent mirror.
This is a simple CAS background; however, it would make it difficult to remove the background from your sims so I wouldn’t recommend it for photo editing purposes. But if you’re just looking for some Sims nostalgia, it’s a perfect Maxis Match Sims 4 cas background addition!
5. Sims 4 CAS Background Pastel Purples by Shasims
