High-quality recreation of the iconic Japanese Showa-era patterned glass "Ginga" style. This master material is designed for professional architectural visualization and nostalgic interior scenes, featuring a smart node setup that automatically applies the pattern to only one side of the glass using Backfacing logic to replicate the realistic structure of vintage glass. You can easily customize the pattern scale, glass color tint, and bump intensity via the Group Input to suit your specific project needs. The material creates beautiful, sparkling light refractions with its realistic plump convex star details, while remaining optimized to work with thick glass objects by hiding the pattern on the back and side faces automatically. It is a perfect tool for adding a touch of vintage authenticity to windows, cabinet doors, and retro lighting fixtures.
