I tested rev2069 and the export is ok now.
Collision seems to be working now, I played several games with multiball and everything seems fine.
I have a couple of questions 
1) Why I have this?


That's the same model, the left one is exported with the whole table, the right one is a single mesh export. No materials there, neither lights, but they look quite different.
2) It seems that the lightning environment changes from desktop view to cabinet view.
If you look at these 2 screenshots, you will notice that the right (wire) ramp shines in desktop view (more or less that's the effect I want), but in cabinet view the shininess is lost; in the meantime the left ramp shines (under the airplane) while in desktop is ok.


3) Playfield reflection and/or shadows (like we see in FP) : is this possible?
Thanks again for all the work you are doing, you guys rock!
