Raymod I think the PAPI issues you are experiencing are FSX SE related (check video). Also want to point out (@ developers) that there are other parts of "Ponta de São Lourenço" (not only the lighthouse islet) that have a poor mesh with some flat terrain. Please check the following video (mesh issue is shown on the end).     Regards, Luís   PS: The shared BGL fixed the lack of 3D Lights on both islands.
