MK-Studios has published on a Facebook post new pictures of their work in progress Keflavik Airport (BIKF). The screenshots concentrate on several details on the airport such as the terminal, jetways, some hangars and a few other objects. PBR materials are of course in use. However, no in-sim previews have been posted so far. As per MK-Studios roadmap published a few days ago, it is expected for a Q1 2020 release.
You will find the screenshots below.
