Developer Airworthy Designs recently took to Facebook and posted some beautiful progress shots of the upcoming 1.5 update for Princess Juliana Airport (TNCM) for X-Plane 11.
As evidenced in a few of the shots, and confirmed via Facebook messages with the developer, much of the time has been spent on adding Physically Based Rendering (PBR) support for runways. When asked for everything that is included in the 1.5 update, we were provided with an internal task list of over 40 items that include things like animated jetways, animated flags, airport ground services, ground traffic, improved night lighting, and more.
Airworthy Designs said that they have also worked to improve performance on older systems, and they are hoping the update will be ready for release within the next month or two.
