i have done my research and have gone through a lot of forums regarding the issue of apron lighting. as what i understand, having the emitter set at 0.00 will show apron/ramp light effect when you start FS more than 10km from the airport but with this, you get a very solid and very bright effect from a very far distance. so the other solution is to create a controller. my question is, how exactly do you make a controller?-is this also an .fx file?-should this reside inside the effects folder?-what filename should you give this file?here's a sample of my controller-----------------------------[Library Effect] Lifetime=5 Version=2.00 Radius=200Priority=0 [controller.0]lifetime=0.0, 0.0 type=3 distance=5000.00, 5000.00delay=10000000.00, 10000000.00x offset=0.00, 0.00 y offset=0.00, 0.00 z offset=0.00, 0.00effect.0=fx_apronlight, 0.00, 0.00, 0.00, 0.00, 0.00, 0.00, 0.00, 0.00-------------------------------------------------------------------------i saved it as apronlightcontroller.fx and placed it inside the effects folder.but still, my apron lights disappear when i start away from the airport and does not show when i arrive at the airport. but it shows if i start my fs inside/near the airport. did i do something wrong in the process?

Hello:You may wish to browse some of the results in this search result at FSDeveloper using these Search Keywords: Light, Effect, controller :http://www.fsdeveloper.com/forum/search.php?searchid=1042860Indeed a Controller file gives greater control over light visibility than when an Effect is associated with a 3-D object via an Attach Point.The Controller Effect file ("Cntrl_*.fx") is the other type of file sometime used in addition to the basic Effect file ("*.fx")PS: Also see the FSX SDK document "Creating Special Effects"Hope this helps ! :( GaryGB

hi thanks, unfortunately, my search did not seem to get any keyword matches.although i was able to find another solution from another forum by simply changing the particles from 19 to 25.indeed, the controller will only work if the emitter is set to 0, but that would result to a very solid white spotlight.i think i can be happy with the spotlights appearing 10km away.thanks again.
