Gentle CAS Lighting by Northern Siberia Winds is by far one of my favorite Sims 4 lighting mods. It removes the dull gray filter from EA’s default lighting and replaces it with a softer glow and shadows. This makes your Sim’s skins and overlays look much smoother and more realistic. If you use alpha-style custom content and realistic skin overlays, use this lighting to showcase subtle details.
Follow these steps to install Gentle CAS Lighting 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.
