The filenames for each of the terrain data files that have been added to this object. Files can be added using the Terrain.AddFiles() or Terrain.AddFilesInDirectory() methods. FreeFlyer will search for the required matching FreeFlyer Terrain Index File in the same directory as the raw terrain data file, but with the FreeFlyer Terrain Index File extension (.ffidx).
Note: If any of the indices for the Terrain Filenames cannot be found, FreeFlyer will report an error saying that the Terrain object configuration is invalid because one or more index files couldn't be found.
