Motivation Method Follow the link to install the add-on to blender https://github.com/eliemichel/MapsModelsImporter Install the RenderDoc program on windows, to inject process to Chrome to fetch 3d data from it. Create a shortcut to launch chrome with some additional debug flags Run chrome, record the process number, pause. Inject to that number in RenderDoc program Then start chrome and go to google map to your favorite buildings Capture through RenderDoc. Save to rdc files to disk. Load that rdc through Blender! and you have your 3d models! Post processing Join the patches to a single object. And merge vertices by distance。 Process texture and stuff to retain a single kind of material with the color. See the youtube video for a tutorial.
