The model looks very much like the real ship (Google it if you don't believe).
Material and Rendering:
Preview pictures are rendered by Vray in 3dsmax but the model is devrayed to make it compatible with most 3d applications. We have properly named the materials. So for visual enhancing materials like GLASS,CHROME,POOLWATER. You should replace them with materials of your own liking in your favorite 3d application. I also recommend adding some falloff reflection to most materials.
There is no multi_material used in the model for better compatibility with all 3d application.
Seawater(just a big plane) and HDRI cloud used in the renders are not included in the package
Naming & SmoothingGroup:
models are all properly named. By combining with 'select by material' you can select any parts quickly in any 3d application.
All objects are edge-splitted based on smoothing group assignment. So even if some applications don't treat smoothinggroup nicely can handle this model. Of course this will increase the vertex count but you can weld it back if you like.
Contact support should you have questions. We will try to address your concerns as promptly as possible.
I suggest you download the downloadable file - 'tatoosh-jpgs.zip'
