Flexi Building Generator is a procedural building system for Blender, driven by Geometry Nodes and fully integrated with the Asset Browser. The tool workflow combines procedural modifier generation with precise edit-mode node tools, allowing users to manually designate plain walls, stairs, and specific rooftop elements across their structures.

The system includes ten architectural styles comprising over 200 individual modules, alongside fifty pre-configured buildings. Users have granular control over materials, with five color palettes available per style and direct parameter tweaks for walls, windows, and ornaments. For nighttime sequences, the generator offers individual light controls and parallax mapped interiors, spanning residential, office, and commercial layouts with varied curtain setups. Advanced users can also utilize the included base module system to create custom architectural styles from scratch.
