Problem importing model in Unity

Unity Engine
1

I am trying to use the model in here.
Most of the model imports ok but I’m having problems with the hadns and head, they do not show up at all when importing into Unity.
Basically what I’m doing is opening the source file in 3ds Max 2011, adding the UVW map modifier, and exporting to FBX.
Then just dragging the file into Unity 3.
Does anyone know why this is happening?.
Thanks.

I haven’t used max in ages, but does it collapse UVW during export?
Also does model not show up at all, or maybe it’s just too small to be seen? I once had a similar problem and it turns out the models were tiny so I couldn’t see them.
