thanks ! After some failures I finally think I have found the way to get these
tens of thousands of lights working as they should...
WITHOUT CAUSING FPS-drops ! both when viewed from the air from a plane and when on the ground, driving through illuminated cities...without the
need to switch any light on by hand.
some more weeks to develop unfortunately.
At that point the task will be yours to either hand-place my new lights in the scenery editor or find open-data about lamp-post positions on the web..so that I can add them to the "streetlight-database" ....or a way needs be found to access the road data and place lights just on the side of roads.....but ONE STEP AT A TIME
