I second heneusa's suggestion to post this thread in the CC forum.
The bottom line is if you can get the file to load into GMax or 3DS Max you can get it into NWN. However, it's during that conversion process (say, exporting from Rhino to .obj and importing that .obj into 3ds Max) that the most problems crop up. Smoothing groups get lost, meshes are imported with every triangle as an individual subobject element, faces can be doubled unintentionally etc. Once something is in GMax/3ds Max and presumably in a form you like, there are very few things that can possibly crop up as far as getting it into the game.
The real trick is coming up with a good workflow. If you don't have 3ds Max and are instead using GMax, you may have to resort to some
minor gymnastics to get your mesh loaded.
Edit: Oops, left out NeverBlender. I wanted to also second Heneusa's comment about NeverBlender looking promising. Blender already allows importation of many file formats that GMax does not so it could become a great middle-man/destination for file conversions. You can learn more about this new version of NeverBlender
