The OpenSceneryX project is a free to use library of scenery objects for the X-Plane® flight simulator. It is a collaborative effort by members of the X-Plane.org community, providing a range of high quality scenery components for authors to use in their scenery packages.
The library contains many pre-built 3d models including buildings, aircraft and vehicles as well as a large collection of ground markings, ground furniture and vegetation.
This repository contains the installer which is written in Xojo, as well as associated build and maintenance tools written using shell script.
