This is a render of the Earth on the dark side. It might not be accurate but I thought it was cool to make it like this. I have Andrew Price from BlenderGuru to thank for the tutorial he made so I can improve my creation of planets. You can use this for commercial purposes and order prints if you like from my DeviantArt account.
Blender Render workflow for creating maps [ID, AO, NORMAL]
This video tutorials covers my workflow in regards to creating color ID maps, AO maps, and Normal maps using the Blender Internal engine. There is no loss of quality using the Internal engine instead of Cycles for these particular tasks, and often times it is easier, and quicker to do them in Internal vs Cycles.
