About This Mod
In Phases CAS Room is a dark alternative CAS background with a grungy bedroom setup. The room comes with a full-length mirror, checkerboard wall art, posters, books, an old TV, plushies, and plenty of clutter for an emo-inspired aesthetic. The creator notes that you should expect Infant, toddler, and child Sims to appear as though they’re floating in this CAS room. According to them, the background isn’t broken; this happens because of the style of CAS room used.
