Here is a free Earth project with 4K maps to use with Element 3D. You can also use the maps with CC sphere to recreate the project without Element 3D, we even have a very old tutorial to show you how. Watch the Blue Planet.
To customize the Earth, you can open the Element 3D layer and turn down the illumination map to shut the lights off.
NOTE: Please place the Earth folder inside “My_Models” folder
