I just emailed you a download link for the reproduction scene through the forum.
Please note that the exported mesh has inverted normals, i.e. when I set it in the MeshFilter of a GameObject I have to rotate the GameObject 180deg on z to become visible.
EDIT: Inverted normals in the exported mesh is not a problem anymore. It was originally a problem when I was experimenting with various settings.
