This is the third and final part of my series of tutorials showing how I created a model of the Earth. If you missed part one, I showed you how to create the simple model and add the basic color/bump image maps. In part two, I showed you how to add shader layers for the ocean, clouds, and the night city lights.
Because LightWave does not have volumetric shading support, we are going to fake an atmosphere glow using a flat, transparent object. Using the node editor, we will control the transparency based on its relation to the light vector.
