In this tutorial we will go through the steps of creating a realistic globe and clouds using only shaders. We will add some atmosphere to the horizon with a Volume and Volume Collector shader. We will also light the scene using a Physical Sky connected to a Sky. This scene would make an ideal backdrop for a fictional film about some unfortunate astronauts, for example. Many thanks to Will MacNeil at MPC for providing the scene used for this tutorial.
You will need to download and use these high resolution textures for use with this scene. Remember to convert the textures to .tx format prior to rendering.
An .ass file is available here.
