I know that there are plenty of this kind of images on the forum but I just wanted to share this with you guys.
Took me an hour to set this up.
Nothing fancy, just two spheres and a light.
Minor compositing with Blender nodes.
Cycles 100 samples
1366x768
Three textures, color, normal and bump
Hope you like it.
Texture credits goes to the NOAA.
Happy blending.
Juan Ignacio.
