Trouble exporting site model in Troubleshooting Posted November 7, 2018 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?
