35+ Aesthetic CAS Backgrounds for Sims 4!

customized cAS backgrounds for the Sims 4

The typical Sims 4 CAS panel has a recognizable blue background. Although we love this signature feature of the Sims 4, the CAS backdrop can be changed, just like many other elements of your favorite game. In fact, you can change the scenery in Create-A-Sim mode as frequently as you want, by adding a new, customized background before you launch the game.

To add a new CAS background, first, find the background you like, download it, and unzip it if needed. Then, copy the downloaded file to Documents>Electronic Arts> The Sims 4> Mods, and you are good to go.

You can use only one background at a time, so make sure you have only the one you want to currently use in your Mods folder. If you want to replace the old custom background with a new one, delete the old one first, and then paste your new favorite in the mods folder. 

So, if you are interested in some fresh CAS backgrounds, you are in the right place. We have created a list of more than 30 customized scenes for you to browse and download. Enjoy the ride!
