Much obliged for your answer. I guess I'm still stuck at the 'how'. The aircraft I had built are from v11.20, so the question.. is there a place to select "glass exterior" in maker? I found those selections only in misc objects. ie. how would I make that selection for all parts (fuselage, wings, nacelles, pylons, etc.)...do I have to transfer those parts into misc objects (if so , how) or are we only talking about imported(non-xplane generated) objects?. Thanks..
