OSG exporter: worse output in newest version?

[tokola]

I understand the potential complications from models created in other programs. However, as I mentioned above, this specific model was edited with Max 2012 and exported beautifully with the old OSG exporter. The exact same model was opened with Max 2015 and the result with the latest OSG exporter is what you see (unsmoothed normals). I really cannot see how this can be related to the creator of the model. Something must have changed between the Max or/and OSG exporter versions to justify this. I hope the artist can shed some light...
