Earth Elevation, Topography what it will bring mountin & make earth to not be a flat planet :)
Californian rocky mountain Everest
One way to control elevation is done by changing offset value in Earth.cfg, but it is depended by EarthHeight.dds texture
VertexHeightMap
{
offset = -1000.0 //-2000.0
deformity = 17300.0 //15600.0 //7000 // 5000
map = RSS-Textures/PluginData/EarthHeight.dds
}
For create EarthHeight.dds it was use http://www.ngdc.noaa.gov/mgg/image/2minrelief.html + http://visibleearth.nasa.gov/view.php?id=73934 & diferite special layer to control brightness, tone, colour variation ...
There are two versions of EarthHeight.dds, the difference is given by the lightness and an extra layer for have 2 situation for more testing option
