Okay,so it is possible to change "sea_level" in Outerra's configuration, and here are some screenshots to prove it.
So this is Switzerland, but sea level has been changed to 1440 meters above sea level (this last sentence has no meaning at all...
)
Look at what those Alps have become with sea level at 1440 m. So this is the Rhonefjord (Rhone Valley).
The long Y-shaped valley system at bottom center is the region of Zermatt / Matterhorn / Saas Fee etc.
Rhone Valley and Dents du Midi, at the bottom left of the previous photo.
And this is what can be seen from the Jungfraujoch, in Bernese Alps.
Compare with a (really zoomed in) photo on my Panoramio account:

Le Chasseron, in the Jura Mountains. On this real photo it's the mountain at the top left corner:

)
Thanks for watching.
