In November 2018, Richer Simulations announced the first phase of beta testing for their St.Vincent / TVSA scenery. On their Facebook post, brand new screenshots show that development is nearing its closing stages, although no date or price has been set for release.
From what we know so far, the main island of St. Vincent and the Grenadines has been modeled from 5-meter resolution LIDAR data including all major landmarks. The airport itself has been modeled upon detailed aerial drone photography. Ground polys and taxi lines will use ultra high-resolution textures each complete with specular detail and bump maps. Static ground vehicles and aircraft will be included, and the main terminal building will include an optional interior with transparent glass.
