Great job and really enjoying the heck out this classic. I did ask Gary about the lack of a "crew" in the external view and if he had any plans to possibly add a few in the future. . .
#1. I didn't have any, but that could come out as a possible update in the future. The original model I created, exceeded the xtomdl vertex count by well over double, As I had a complete interior. The current model contains somewhere around 85,000 vertices. The original was somewhere over 150,000, so it did have a crew to begin with, but they went in the subsequent cleanup to lower the point count.
As I told him though, it certainly doesn't diminish the enjoyment factor at all. Thanks Gary!
