Surface normal in a mess when exporting

Hi,

I'm very new to MoI (and very pleased with it), and i have a big issue : i have done a building in MoI but when i export it to modo (either in lwo or obj), the surface normals are in complete mess. I have tried deleting the surface normal map, i have run a polygon align tool, but it does not change anything. The building is 52000 polys, full of bevels and the faces are separated on export to avoid artefacts, so it is absolutly impossible to repair it manually. I have about 30 buildings to do and i'm quite stressed by now...

Anybody could help ?
Thanks in advance.
