Thank you, Nidhogg and Nems.

Yesterday i made with success a terrain export from icex2.0 to WED. The problem was that i selected a few export options that 3dgs Extra Edition doesn´t supports. The textures appear now correctly (low resolution), but it´s enough for me by the moment, because now i can test the things i want to do with a very huge terrain.

Bye and thank you
