55 As of April 25, 2026, Wall Decoration Modules have not shipped on the live build (v0.7.5). The current Build Mode supports placing individual decorative items (paintings, shelves, mirrors) on walls, but does not yet offer a structured module system that lets players quickly assemble matching wall treatments. The Q4 2026 update will fill this gap.
