About This Mod
This mod replaces the default Create-A-Sim lighting with sharper, brighter studio lights that make skin tones, hair, and clothing textures look much clearer. There are three versions: red, green, and blue. Use either to highlight details for CAS screenshots and CC previews. Remember, you can install only one version at a time. This Sims 4 lighting mod is compatible with the base game and cats, dogs, and horses.
