Window Maker Add-On earns a spot in the superhive library by keeping a Geometry Nodes workflow behind a single panel, so windows and their wall holes stay procedural and update as they change.
Window Maker Add-On turns objects made of simple faces into procedural windows in Blender. Enabling the add-on adds the BB Windows Panel to the 3D Viewport side panel, where the Create Windows button applies a Geometry Nodes modifier to the selected object. The shape of each window follows the shape of the underlying face, and no Geometry Nodes knowledge is needed since the controls live in the side panel.
Windows can be built in three modes: multiple Window Mode, Double Wing Window Mode, and Fixed Window Mode. A long list of editable parameters lets you personalize and randomize the look, and every part of a window can carry its own material. The add-on can also cut procedural holes into a wall object or a collection of wall objects; the holes are created automatically as windows are added and change as the windows change in size and shape.
All geometry is UV mapped through a vector attribute that converts into a real, editable UV map when geometry is applied, which is also used when exporting to other 3D software. The add-on is released under the GPL license.
Window Maker Add-On is best for blender users creating procedural windows on face-based objects and cutting matching holes into wall geometry.
Window Maker Add-On is completely free to download and use.
Window Maker Add-On has been updated across several Blender releases: version 1.2.4 targeted Blender 3.6, version 1.3.1 moved to Blender 4.0, and version 2.1.1 updated it for Blender 4.2. A bug affecting compatibility with the Stairs Maker Add-on was fixed in version 1.4.1. It is also listed as Blender Extension compatible. If you are on a specific Blender version, check the developer's page to confirm the build that matches your setup before installing.
Window Maker Add-On applies a Geometry Nodes modifier to the selected object, but no Geometry Nodes knowledge is needed. Everything the user works with happens in the BB Windows Panel in the 3D Viewport side panel. After you click Create Windows, that panel fills with options organized inside dropdown menus, and every option is explained in the User Manual, which can be downloaded for free.
Window Maker Add-On can create procedural holes inside a wall object or a collection of wall objects. You choose a wall object and click a button, and the holes are created automatically as you add new windows. Because the holes are procedural, they move as you move your windows and change as the windows change in size and shape. The shape of each window itself is determined by the shape of the underlying face.
Window Maker Add-On is listed as free in this catalog. Licensing terms can change over time, so check the developer's page for current details before downloading. The add-on is released under the GPL license, and it is listed as Blender Extension compatible. The User Manual is a separate download available at no cost, and a video review of the add-on is available on YouTube.
