So here is 4 planets in my collection. All planets are imagination. So I do not know planet size,rotation or other physical data. All planets have color texture,bump map,cloud mask and city light maps.Except
planet Blink. And there is also some node editing too.
Later there is two or more planet collections-earth like planets,gas planets and terraformed planets.
But you never know...
