Trouble exporting site model


I am trying to export my Digital Terrain Model (Site Model) for use in other programs (Maya and Unreal Engine 4). I have consistently encountered problems with exporting to a variety of file types from VW. When exporting to .iges or .obj, for example, I get no data at all.


Most problematic at the moment, is exporting to .fbx format... I get a 3D model, but all the normals are reversed/flipped. The result is that the materials is visible from the underside, but black on top. Why is VW flipping the normals in this way? I get this same result no matter what program I use to open the exported .fbx. What am I missing?

Funny is that not all Faces of VW DTMs are flipped to the same side.

I think the Top Face is always wrong.

(Can't remember if all Texture Bed Modifiers were wrong too or not)


I just got use that a VW DT needs some extra love after import.


But it would be much better when it exports correctly.

Would allow my to do further changes in VW for exchange.

Currently DTM export was one way only therefore.
