I’ve used custom sims 4 CAS backgrounds for years to change the vibe of create-a-sim just for fun. But recently, I’ve been using CAS Backgrounds to create cute graphics and photos for this website (no photoshop required!)

Having a solid color CAS Background makes it easier to cut out my sim from the background of screenshots. All I have to do is take a screenshot of my sim in CAS, then pop the picture into Canva and use their background remover tool.

With the solid color background, I usually have no problems! It’s so simple. I also use Canva to edit my photos and create all of the graphics for this website.

Before you get started with CAS backgrounds, you’ll need to first download a blob remover so you don’t have a blue blob where your sim is standing. (scroll down until you see blob/shadow remover)

Also, remember that you can only have one CAS background in your game at a time. I recommend keeping a mods folder of them on your desktop or pinning this post to keep others handy for whenever you want to switch it up.

This post is all about the best sims 4 CAS backgrounds.

Sims 4 CAS Backgrounds

If you’re a big fan of The Sims 2, you’ll absolutely LOVE custom CAS background #23!😍

1. Old School Sims 4 CAS Background with Mirror by littledica

sims 4 cas background with mirror

This is called the Sims 4 Old School CAS Background 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 perfect!

2. Sims 4 CAS Background Pastel Purples by Shasims
