    // Mixamo Animation downloadeer
    // The following script make use of mixamo2 API to download all anims for a single character that you choose.
    // The animations are saved with descriptive long names instead of the short ones used by default by mixamo UI.
    //
    // This script has been written by gnuton@gnuton.org and the author is not responsible of its usage
    //
    // How to use this script
    // 1. Browse mixamo.com
    // 2. Log in
    // 3. Open JS console (F12 on chrome)
    // 4. Download an animation and get the character ID from the Network tab
    // 5. Then past the character id in the "character" variable at beginning of this script
    // 6. Copy and paste the full script in the mixamo.com javascript console
    // 7. The script will open a new blank page.. you will start to see animations downloading
    // 8. keep the blank page opened and keep on pressing "Allow multiple downlaods"

    // NOTE. This doesn't really work for me, but it was supposed too
    // Chrome will ask you all the time to allow multiple downloads
    // You can disable this as follow:
    // chrome://settings/ > Advanced > Content > Automatic downloads > uncheck "Do not allow any site to download multiple file automatically"

    // CHANGE THIS VAR TO DOWNLOAD ANIMATIONS FOR A DIFFERENT CHARACTER
    // const character = 'aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee'
    const character = 'ef7eb018-7cf3-4ae1-99ac-bab1c2c5d419'
