Great scenery for Aerofly FS2 doesn’t come out that often, so it’s always very exciting when something like the Hawaiian Islands come out. Especially if it’s a freeware product!
The goal of the project is to cover, at least, the main islands of the archipelago and the team have now released the first part, which brings Kauai and Niihau.
To get the scenery to work, you will need to download both the elevation mesh and the actual scenery in two separate downloads. Instructions about how to install everything is on the downloads page (which you can find below).
You can also check out the announcement on the official forums.
