[osg-users] Convert .earth file to .osg format

[Chris Hanson]

You may need to play with layering and other things to get the results you
want at the borders.

Alternately, have you considered if your work could be built through
Virtual Planet Builder, which DOES actually just produce "dumb" .osg
(actually, .osgb is recommended) files?

The result might be larger, but simpler/faster depending on how complex
your layering is.
