Another incredible background cc pack of solid color CAS backgrounds by shasims. They really do make the best custom CAS background for the next time you are looking for some solid color themes to add to your mods folder. The colors are modern and beautiful, and this pack includes a bunch of different nature-inspired greens.
Follow these steps to install Sims 4 Green CAS Backgrounds on your Sims 4 game:
Download the mod file from the link above. Sims 4 mods typically come as .package or .ts4script files.
Open your Sims 4 Mods folder. The default location is: Documents/Electronic Arts/The Sims 4/Mods
Place the downloaded file directly into the Mods folder. You can organize mods into subfolders up to one level deep.
Launch The Sims 4 and go to Game Options > Other. Make sure "Enable Custom Content and Mods" is checked.
Restart the game if it was already running. The mod should now appear in your game.
Important: Always back up your save files before installing new mods. After Sims 4 updates, mods may need to be re-downloaded or updated by the creator.
Platform
The Sims 4 (PC/Mac)
Pro tip: If a mod stops working after a game update, check the creator's page for an updated version. Broken mods can cause the game to behave unexpectedly.
