We need hollow glass parts!!!
Well, a lot of us are using the glass on a aircraft's canopy.
If you think of it, SP's glass is just a block. Its not hollow inside.
It is obvious that a aircraft's canopy is hollow.
Also, if we have glasses, and now we get to see through the canopy, we should have concave parts!!
It would be so much easier to make the cockpit part with the concave block because we can get rid of paneling!
