I run with AS6.5 in FS9 and ASA in FSX (go figure but it works for me). I just installed ultimate traffic II in my FSX world and even though AI appear, there are no contrails. Contrails are checked in UT2 but I was wondering if ASA renders contrails or not? I use REX2.0 for sky/cloud/water textures.ThanksRich Perry

Hi,We don't remove contrails, but if the air is too warm contrails will not appear.Thanks,

Hi ! Same thing here.With UT2, ASA and REX2 Textures. But I use sometimes the Contrails Pro trial (from Flightsimtools) and the contrails appear again. I don't understand nothing :(
