About This Mod
The Antonio 3D CAS Background replaces the plain default screen with a modern, earthy-toned room that feels grounded and realistic. It has a sleek standing mirror, neatly organized clothing racks, and subtle decor that creates the perfect walk-in closet vibe. The large windows open to a San Myshuno cityscape view for a more realistic touch. This background is designed in a clean, contemporary style.
