The surface tiles for VandenberAFB-2006 have an added alpha mask which covers the ocean areas of the tiles. Orbiter's water texture now runs right up to the beach. (Or, more correctly, the California cliffs.) This greatly improves the appearance.
VandenbergAFB-2006 complies with the Orbiter 2006 directory structure, placing the config file and mesh files in appropriate sub-folders.
VandenbergAFB-2006 is NOT a patch for the previous Vandenberg add-on. The 2006 version is a stand-alone add-on for use with Orbiter 2006.
