Buildify is a Geometry Nodes library designed for procedural building creation in Blender. The system relies on a modular approach where users organize their own architectural assets into specific collections. Once configured, buildings are generated automatically based on base mesh faces, allowing users to build structures simply by extruding, copying, or pasting geometry. The library includes premade node groups to accommodate various architectural styles and features native integration with the Blender-OSM add-on for generating environments based on real-world location data. Note that 3D asset kits are not included in the provided file.
