would be cool to fall all the way to the ground.
That was my original plan but it doesn't fit in the challenge rules so...
@KyL if you are thinking to render more low altitude images, remember that there is many resources and useful information in the forum.
Thanks for the link, but I already looked at this when I was doing a similar setup at work. I ended up having a fairly good scene where you can use georeferencing to upres any part of the earth you need. My only limitation though was the cloud texture, as the biggest data source I could find was a set of two 21.5k tiles from NASA. This gives a 43k global latlong, which is the size of all the textures I used for my submission here. (I also made a 86k color map but terragen wouldn't load it). Even 43k is pretty limited altitude-wise. (texture starts to break when you go closer than 800km roughly)
