I scanned my entire computer, but could not find the original object file for the model.  (only had my VOBs) So, I went into Blender, and finally managed to export a new object.  However, in UV Mapper, I could not figure out how to get out separate maps of all the parts.--So, I couldn't attach the UV map of the saucer.

I imported the new object into Vue, and had the same issues again.  However, I split the object, and then the saucer mapped properly, even in the highlight channel ( my recent work files of the model also have a split mesh--but have the mapping difficulties)  As another test, I then saved the split model as a VOB, and reloaded it into Vue.  As you can see in the attached image, the highlighting still seems to work right.  I guess I will now have to just rework everything with this newer vob, relight and recheck all the textures.
