FSX/P3D. The guys from 29Palms and LimeSim have been making some serious progress on the Berlin Brandenburg project due for release this year. In the latest update, the team shows off main terminal present with transparent glass cladding. Transparent glass terminals are becoming more and more of a staple in scenery projects and so far, the new technology seems to have minimal if no performance impact at all. Airports released last year include FlightBeam Dulles, LHSim Budapest, Taxi2Gate Orlando, and Jo Erlend Oslo v2 are some examples of transparent terminal rendering done right. Have a look!
