Window Maker is an add-on that generates procedural windows from simple mesh faces. It applies a Geometry Nodes system under the hood, exposing customization options through a dedicated 3D Viewport side panel. The tool automatically creates and updates procedural cutouts in designated wall objects as windows are moved or resized. It includes three operational modes: multiple window, double wing, and fixed window. Generated geometry features procedurally assigned UV maps and supports multiple material slots for different window components.
