The following is an image created in Vue 10 complete artist edition. The terrain was created using fractal nodes. I used Vue's own trees and made an atmosphere from two atmosphere, Spectral Commulus and Wisps of cirrus with a mixture or low and high altitude clouds. Global illumination lightening was used with some modifications from the default settings.
Minor post processing done in Vue after the render. Texture and Quality settings were kept to a moderate to avoid very high render settings. Image at 15 billion polygons.
