Edit: 7/18/11, I rendered a larger version of this and I am releasing this as stock. Included in the download is a 2560X1600 TIFF file. If you use this please credit me.
There were also a few minor changes which include: 1. Improved the lighting 2. Improved the atmosphere 3. Better render settings
That's why I use Terragen for this type of scene. Vue is excellent for landscape scenes involving plants and trees but for low to medium orbit scenes I prefer Terragen.
Can you make the clouds as a 3d object and import to vue?
thanks
