you have to tell it to import .obj files, its one of the options in the "files" tab i think

is there a way to construct the model with the texture maps to give it the high res look like the preveiw?

I was getting 403 Forbidden errors when downloading the maps, which I assumed were related to the User Agent, since I could open the URLs and download the maps in my normal browser.

I changed two lines in the download_file function, so that I could add my own user agent to the request:

def download_file(url: str, path: str) -> None:
    if os.path.exists(path):
        print("Already downloaded {path}".format(path=path))
        return

    print(f"Downloading {path}")
    opener = urllib.request.URLopener()
    opener.addheader('User-Agent', 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:138.0) Gecko/20100101 Firefox/138.0')

    opener.retrieve(url, path)

Now everything works as expected when using --maps :)
