Importing smoothed objects from Maya 2013

[Parker1985]

I seem to have come across a snag.

Whenever I import a piece of geometry that has been smoothed, it all but disappears in Keyshot4. However, if I reimport the file not smoothed, it shows back up. Is there a way around this issue, or will I just have to make do with non-smoothed files?

I would need an example file so we can take a look. Can you send 2 versions to me - thomas@luxion.com - one smoothed and one not smoothed?

I have the same problem. Always when i combine and merge two meshes and press "3" key to smooth, and then import the scene in keyshot, the merged meshes desappear (only when smooth).
