In Blender you simply append the collection Buildings and apply a particle system to a plane of your choosing. You tweak a few settings, and you're all set.
Other 3D modelers, import the file and create a particle system using these models.
You may have this model for free, even for commercial use;But you have to provide credit to me and a link to this page, and (if you decide to share it) you must give others the same rights I gave to you.
