FSEnhancer developers have today shared via their Facebook page two previews showcasing the upcoming PBR overhaul for the default King Air C90B for X-Plane 11. As the product name suggests, the addon will bring PBR textures to the default King Air C90B.
The developers did also share, the same day, three screenshots showcasing the FSEhnancer addon in X-Plane 11. Compatibility with X-Plane 11.50 beta 11 is currently being worked on.
If you want to download FSEhnancer v0.5, you can do so via the X-Plane.org Forums for free. The screenshots above are showcasing the v0.6.5.
