Hi Michael,

have a very funny issue exporting this obj

as you can see when you load the 3dm file in moi it shouldn't look like this at all...
I fear that the vertex enummeration may be the source of this evil
It happens in Carrara 5 Pro and in Kerkythea, blender and Silo 2 Beta somehow gets along with it and fixes the issue while loading,

best regards,

Thor
