Tonight I came across a good test case on this and thought I would show it to you (Jim,Chris,Damian,and everyone else) so we could discuss it and maybe figure out what to do about it. Maybe I simply have a config issue. Let's see:Attached is a pic I captured from FSX.Point#1 in the pic: Birmingham, EGBB = 20 miles visibilityPoint#2 in the pic: East Midlands, EGNX = 30 miles visibilityPoint#3 in the pic: Shawbury AB, EGOS = 2 miles visibilityI got a near instantaneous visibility change moving from the Birm/East Midlands area toward Shawbury.Ok, now I hand the ball off...where to begin? :)http://forums.avsim.net/user_files/160105.jpgRhettAMD 3700+ (@2.5 ghz), eVGA 7800GT 256 (94.47), ASUS A8N-E, PC Power 510 SLI, 2 GB Corsair XMS 3-3-3-8, WD 250 gig 7200 rpm SATA2, CoolerMaster Praetorian

Hi Mace,Thanks for the interesting post!Due to some internal programming from MS this is still an issue right now. Visibility smoothing is still lacking in different degrees. Right now the best we can do is ask that Enable FS Haze is checked On. We will continue to work on this issue.Thanks,Jimhttp://www.hifisim.com/Active Sky V6 Development Team Active Sky V6 Proud SupporterHiFi Beta TeamRadar Contact Supporter: http://www.jdtllc.com/AirSource Member: http://www.air-source.us/FSEconomy Member:http://www.fseconomy.com/

Well, it's good to know that it's not a configuration issue on my part.I half suspected that it was.Or an issue with FSUIPC.It was odd, I found an invisible "line", and I could fly back and forth across that line and the visibility would shift suddenly from 2 miles to 20 miles. That line signaled the demarcation between the to weather stations, it appears.I saved the wx file because I thought it was interesting.If there is anything I can do to help on this issue, let me know.RhettAMD 3700+ (@2.5 ghz), eVGA 7800GT 256 (94.47), ASUS A8N-E, PC Power 510 SLI, 2 GB Corsair XMS 3-3-3-8, WD 250 gig 7200 rpm SATA2, CoolerMaster Praetorian

He Rhett,Yes, that "point" of the shift occurs exactly when a "new" closest station exists with a different visibility value.This highlights how horizontal visibility areas are transitioned in the FS9/FSX weather system. Far from ideal, but we are indeed applying several ideas in this department to really improve things if it all works out.Also, note that the vertical visibility transitions are much improved in FSX by default... FSX also now supports multiple visibility layers. We're of course working hard to take advantage of all this :)Best,

>>This highlights how horizontal visibility areas are>transitioned in the FS9/FSX weather system. Far from ideal,>but we are indeed applying several ideas in this department to>really improve things if it all works out.>One idea I thought about, would be to use invisible "fake" wx stations, interpolating the data (visibility data, in this case) of the nearby stations.I think that's pretty much what you do with oceanic wx stations presently, anyway.I guess the trick would be to set a proper "location" for the invisible fake wx station...anyway that's one thing I was thinking about regarding the vis shifts.Too bad that in FSX Microsoft got the vertical visibility shifts MUCH better, but not their horizontal ones.RhettAMD 3700+ (@2.5 ghz), eVGA 7800GT 256 (94.47), ASUS A8N-E, PC Power 510 SLI, 2 GB Corsair XMS 3-3-3-8, WD 250 gig 7200 rpm SATA2, CoolerMaster Praetorian
