This tutorial is the result of many hours of designing, test rendering, and spell checking. Students build two different Earth models, and learn how to achieve details such as masked specular shading, cloud shadows, and city lights. All the maps used in the tutorial are free, and instructions on how to find and download them are provided.
For more example renders and clickable links to the various maps, see the Earth page of my planets library.
Note: I have achieved several improvements over the models demonstrated in this tutorial; when Blender version 2.5 is released, I plan to write a 5th tutorial edition to reflect those improvements.
