If you don’t like how your Sims 4 NPCs look, you can change their look. You can alter their entire appearance and not just their work outfits. Here’s how: 1. Open your previously activated cheat console by hitting Ctrl + Shift + C. 2. Enter the following line: “cas. fulleditmode”. 3. Press the Enter button. 4. Go to the NPC you want to edit and press Shift + Click. 5. Choose the Modify in CAS option and make your changes.
