Japanese Building Generator is a procedural Geometry Nodes modifier for Blender that builds Japanese castles, pagodas, pavilions and temple halls. Drop it on any object and you get a finished building with its own materials, then shape every storey, roof, gable and stone with sliders.

• Five ready-made buildings: Castle, Pavilion, Pagoda, White Castle and Temple Hall, each a node group asset with its own defaults and materials.
• 69 parameters in 8 panels: storeys, footprint, roof curve and corner upturn, gables, pillars, brackets, balconies, windows, stone base, stairs, ivy, spire and materials.
• Real geometry details: round tile rows, ridge-end tiles, rafters, bracket sets, shoji lattices, barred windows, 3D stone courses, lanterns and ivy.
• Materials included: 2K PBR materials from ambientCG (CC0), packed into the .blend.
• Two scenes: an outdoor set with grass, gravel and trees, and a studio set with a checker floor and a camera per building.
• Requirements: Blender 4.5 LTS or newer (tested in 4.5 and 5.2). No add-on to install.
