The Antonio 3D CAS Background is a modern editing environment with a simple and clean design. It’s characterized by neat aesthetic, earthy tones of brown and black, and luxe furnishings. The background has a huge mirror that reflects your Sim, allowing you to see how they look at the back. Most of the items in the background, except for the mirror are blurred to highlight your Sim.
Follow these steps to install Antonio 3D CAS Background on your Sims 4 game:
Download the mod file from the link above. Sims 4 mods typically come as .package or .ts4script files.
