Troubles with .ter files imported from dem files

[Lalla]

I've troubles with ter file imported from dem files.
When I open ter files, I've a map as shown on map.jpg and sky is black as shown on render.jpg.
How can I avoid this?
Thank you.

The sky not showing has nothing to do with the terrain's source being a dem. 

Either your camera is too high or your sky is too low, or too small.  Increase sky size and lower camera below sky altitude.
