Big thanks to Blender Guru and NASA on this one, all imagery provided free by NASA from their online library, started with a UV sphere and an image texture node, added in clouds, atmosphere, night lighting on the points of the earth not being hit by the sun. Had real fun with this project and I learned a lot about Geometry, bump and shaders, really pushed myself past my comfort zone by creating a fly round animation alongside this. Would love to give the other planets a go now I have the know how to do so.
