After to give it a first try, max 9 imported the obj with a lot of flipped faces in naceles and saucer, and missing textures.
In the second try, the mesh was imported in Deep Exploration and re-exported as a rh binary. This time, the imported rh mesh in max 9 looks exactly like the one showed in the rendering you posted at scifi-meshes, and I found what is going wrong there. The windows at rim's front, have unwelded vertices, but they are so closelly superposed that it's impossible to see it without to look closelly that area.

Welded all of them with a single command, but it didn't work. So, pressed undo and started to weld them one by one. In a small area of test, it worked. Looks like it can be the solution, but it will take sometime to be concluded.
Anyway, looks like that place is the unique area where the problem occurs. Just a minor trouble. Still, a DAMMED fine mesh Al. Thanks for sharing :thumb:
