I have tried various ways to use relief data from:
http://apex.ngdc.noaa.gov/seg/topo/globeget.shtml
I imported the data in 3Dem and tried to get it to export it to a 3D-fotmat. Did not work for me. Though I got some 3D pictures and flyby's.

Then I tried to export to Terragen from 3Dem. But no usable exports from Terragen either.

Plugins for Terragen:

I guess we need a import plugin for some kinds of DEM. GLOBE would be nice, though it is not that detailed.
Anybody with tips?
