thebest1. I've marked the element yu're looking for in "pink" with a cirlce arround it. The element you're looking for is placed a bit outside of the regular cockpit structure. maybe i haven't seen it when i've done the experiment with HT or they've made some minor changes on the model.
Whatever. Simply try to fill the area arround the cockpit sturcture largely with the color you use for the structure and it will work.
Look at the screenshots attaches.
I hope i was able to help you a bit
