Getting started

1. In your project, use File › Link (to keep it updatable) or File › Append, open M42_WindowGenerator.blend, go into NodeTree and pick M42_WindowGenerator.
2. Add any mesh object (a simple plane is fine) and give it a Geometry Nodes modifier.
3. Select M42_WindowGenerator in the modifier.
4. Adjust the parameters below. Tip: duplicate the object (Alt+D) to place many windows that share the same settings.

Open M42_WindowGenerator_demo_lite.blend to see a ready-made scene, and the PDF user guide for illustrated explanations of every setting.

Parameters

Window

• Width / Height: overall size of the opening.
• Thickness: depth of the window frame.

Surround

• Material: stone material of the surround.

Export to game engines

Apply the modifier to turn the window into a regular mesh, then export it as usual (FBX, glTF…).
