Hi, maybe one of you can shed some light on this.Stock airports do not seem to have this problem, but add-on scenery obviously causes a graphics problem on my system.Recently I added Aerosoft´s LPFR to my collection. I very good looking airport. But I noticed there was very little traffic. At least that was what I saw. Until I noticed ATC directing AI around that appeared to be invisible. After a while I noticed only the winglights were noticeble. On the stock airports these planes are visible.I also have this problem at TropicalSims TNCC. And I noticed this when using a different AFCAD at KATL.IT has to do with graphics, but can I adjust that? My video card is mentioned below.At first I used to run in DX10 mode since I noticed my night cockpit wasn´t showing with the stock aircraft, now I have returned to DX9 since I mainly fly the PMDG MD11 without that problem. I have a feeling dX9 in combination with my card could cause this.Any help or suggestion is appreciated.Thanks,Menno

Problem occurs with FS9 AI models, or FS9 made scenery with FSX. Either way, only way around it is disabling aircraft shadows on ground. Then AI will be visible on those airports.

Turn "aircraft cast shadows on the ground" off......uncheck the option under Options, Display, Aircraft (tab). I don't remember the technical explanation but it's a known issue and I believe caused by texture conflict (addon scenery vs AI aircraft)George.
