Still unresolved - non complete overcast

Recommended Posts

The squares are gone after aplying the beta patch but I was flying around chicago today and into last night and all stations were reporting overcast but there were many big holes and lots of blue sky around in the snowstorm. Perhaps I am being to pickey but I do remember a time when there was allways a complete overcast when their was one with ASE not to long ago. Maybe I just did not notice it as much as I do now. Seems like there was redered another layer immediatly above the first one that solved this, I remember reading about that as well in the ASE or AS6.5 manual of the past. I notice there is just one layer now, anyway could we get that double layer effect back again? I'll give you 10 bucks.Thanks

Thanks Damian, Chris, and all the Hifi team for such a wonderful addition to the ActiveSky legacy.Over London today with the CLOUD_COVERAGE_DENSITY=12 tweak :2012119105420304.jpg

In which file is this parameter located ?Thank you,Ken BoardmanI think that I found it (fsx.cfg?). I changed it from = 8 to = 12. Look forward to testing it.Thanks again,Ken

I can get overcasts...but not for long.Enroute with weather calling for overcast all the way, I get overcast at departure and arrival but big, huge holes enroute...always.Overcasts are almost always quite thin...and from the aircraft looking straight down you can almost always see the ground.There is a big problem with the AS2012 and ASE wx generators, but it is the same for FSX weather and REX weather, too.Good luck on getting this BIG wx problem fixed.

Well, this is exactly why I made this post : because I don't get what you describe. At all. With the 12 tweak, I can get REAL OVC (as stated in the title and obviously shown on the screenshot) for long periods, exactly where needed.Which means* that they are not thin. Not thin at all.* that I can't see the ground (look at the screenshot and tell me where you see the ground ?)So NO this is not a big problem in AS2012. Most of the problem lies in FSX (most ! This doesn't mean that AS2012 cannot be improved, of course). Have you at least tried the CLOUD_COVERAGE_DENSITY=12 tweak ? Because without it, I get exactly the same as you. But with it, my OVC most of the time look very realistic as per the above screenshot. It definitely changed my perception of weather in FSX.

Driftdown,Yes, I'm a long-time user of CLOUD_COVERAGE_DENSITY=12 tweak, and I think every other wx tweak around.Would you please post your AS2012 settings. There may be something in there that I am missing.Thanks,

Hi Zach, sorry I saw you post too late. I use AS2012 on a secondary PC which is off right now, and I'm off to bed. I'll post it tomorrow after work.

Downdrift,Thanks for your FSXOptions.cfg file. It was similar to mine.For me, I still get breaks, often big breaks in the overcast when there should be none.I am testing FSX, REX, ASE and AS2012 weather engines and textures. Their accuracy is close to the same.My best wx is close to departure and arrival airports. Enroute is the least accurate if it is a heavy weather day.Current wx engines, to my knowledge, are unable to cure my breaks-in-the-overcast problem and it includes the absense of low overcasts (i.e. 200 feet, 400 feet, etc.)Low visibility masks the absence of low clouds on approaches.Low visibility simulation is quite good.I can get accurate clouds only by manually loading FSX weather...with lowest visibility (1/16th mile) in clouds.To my knowledge, FSX can accurately render METARS wx but only by manually loading it directly into FSX.I believe current wx generators at this time are unable to solve the FSX breaks-in-the-overcast and low-cloud problems.

Hi Zach, if you have the same kind of settings as mine and use the 12 tweak, and stil experience the gaps then there is indeed still a problem with OVC. I must admit that since extensively trying the 12 tweak I have almost (emphasis on almost) never had any more OVC problem myself. Do you use the 20 layers as well ?I never generate weather manually to be honest so I wouldn't know. I always fly real time weather.As for visibility, I indeed remember some OVC conditions in the metar that were poorly rendered with huge gaps that were masked on the floor by the poor visibility, but even with that you could still see the gaps shapes and it was really ugly. However since using the 12 tweak I haven't had these anymore.There obviously is still room for improvement in AS2012 : for example temperatures aloft at high latitudes which are completely crazy : I frequently get -8 0 °C or -90°C which evidently make the fuel freeze... And I am far from being the only one with this problem.But for most flights, since using the 12 tweak, it really has changed my view of weather depiction in FSX. And in "middle" latitudes, temperatures and winds aloft are really great, allowing for very precise fuel calculations, which is great.

Driftdown,I am now using your FSXOptions.cfg file. So yes on the 20 layers.I have long used the "12" tweak.On AS2012 Graphics, are you using highest resolution and 32 Bit (HD)?

At the moment I use 1024 and 32 bits. I used 4096 at the beginning but I am not convinced the price to pay in terms of performance is really worth it. And moreover I am also wondering if I don't find the 1024 more realistic when actually flying. For sure the 4096 look better on still beautiful screenshots but I don't fly to make screenshots. I fly for the flying itself.I'll have to make more testing with the 4096 to have a definitive opinion but for the moment I'm quite happy with the 1024/32bits.Hope this helps.

All right, a few more observations on that matter : left EGLL to EDDF, where the metar was quite interegesting and alluring :EDDF 251020Z 05005KT 1600 BR FEW001 BKN002 BKN005 M01/M01 Q1023 BECMG 3000 SCT002EDDF 250950Z 06005KT 1000 R25L/1500VP2000D R25C/P2000N R25R/P2000D BR SCT001 BKN002 M01/M01 Q1023 BECMG 2000 BCFG SCT002EDDF 250920Z 05005KT 0800 R25L/P2000N R25C/1100VP2000U R25R/1300V1900U=EDDF 250850Z 06005KT 0700 R25L/1200N R25C/1100V1700N R25R/1000N=EDDF 250750Z 04005KT 0600 R25L/1200U R25C/0700V1100N R25R/0650N FZFG VV/// M02/M02 Q1023 NOSIGFirst thing : I had very satisfactory OVC coverage all along the route over Europe, as planned (cf. TEMSI chart and enroute metars) :201212510185217.jpg2012125101810427.jpg2012125101816135.jpgBut, when arriving not far from EDDF, where the metar was undoubtedly horrible, both in terms of clouds and visibility, I had two surprises :first AS2012 was using advanced interpolation (!!! on a huuuge and important airport such as EDDF ? With a perfectly normal metar ???) instead of the METAR, and it's only there that the clouds starting to gently scatter, and the visibility was wonderful... Exactly the contrary to what I was expecting. I didn't want my end of trip to be ruined by poor weather rendition and decided to try to uncheck the "prevent cloud redraws" when I was overhead EDDF at about FL110. Immediately the clouds changed and I passed from a gentle SCT (even though AS2012 advanced interpolation was claiming on the wx report : OVC001 !!!!) to a real cloudy BKN/OVC sky.Good to know I said, without the prevent cloud redraws, weather depiction on arrival is far better (although I don't understand why since from when I started AS2012, loaded my flight plan and when I arrived, the metar scarcely changed, but anyway...)Procedure, establish on the ILS and instead of coming out of the clouds between 1000ft to 200ft above ground as I would have hoped and expected (and as both METAR and AS2012 were claming, as AS2012 was still interpolating the thing into a OVC001 !!!!) here I am at 2000ft, having gone out of the clouds a loooooong time ago (at about 4000ft).Knowing that EDDF's elevation is 364ft, with OVC001 (AS2012's interpolation) or even with the real BKN002 of the metar, I should have had the pleasure of a real challenging instrument approach until at best 600ft, at worst 1000-1200ft.201212511135484.jpg2012125111312653.jpgWhat is funny is that the rendition DID go right after a while... After I waited for about 10 minutes on the ground, parked at my stand. Useless.So there IS indeed something to do here. I'd be happy to hear from Damian or Chris. Or submit a ticket if it's better for them.

Driftdown, one thing I noticed in those spot images posted here is that the cloud cover perspective is from an oblique angle. From that perspective it is hard to see the "holes" in the overcast below. The breaks in overcast - in my situation at least - are immediately around and below the aircraft (while looking out towards the horizon gives me a perspective similar to the images posted here).Setting MaximumCloudLayers = 20 in FSXOptions.cfg and CLOUD_COVERAGE_DENSITY=12 in FSX.cfg did not resolve the issue for me.Maybe it's because I'm just a little delirious from the flu (yuck) but do I understand correctly that PREVENTING cloud redraws MAINTAINS the overcast? I got a little lost in your wording - sorry...

Hi leeflet,no it's not only a good angle for the screenshot : it's really OVC, even under my plane. First thing I checked :) It's just that a screenshot from top to bottom doesn't show really how large the OVC cover can be.AS for the "prevent cloud redraws" it didn't maintain the overcast it put it back : I had a very good OVC depiction during all the cruise and the beginning of descent, but as soon as I reached overhead my destination, which moreover showed OVC in its interpolated METAR (FIrst : it should not have been interpolated at all, and second it's even worse because the interpolation was supposedly OVC), the clouds started to disappear and a very nice SCT/FEW was depicted, with perfect visibility. As soon as I unchecked the "prevent redraw" the depiction was back to a OVC as it should have been... however the OVC depicted and the visibility were not as they should have been. First the base of the clouds should have been much much lower, and the visibility worse. So the "prevent redraws" did not maintain the OVC as it has disappeared, it merely put it back, albeit in a not perfect manner.Hope this clears things a bit.

Hi PeterYou can locate your fsx cfg here C:Usersyour nameAppDataRoamingMicrosoftFSX in vista/7 and if you want to edit the cloud coverage its in the cfg under [weather].

No problem,It isn't listed as fsx options cfg it just says fsx and along to the right it should show cfg file, thats what you want to open.

Oh, you mean the normal fsx.cfg. Ok it looks very different to the above mentioned; e.g. no entry for cloud layers etc.Peter

No it definitely is NOT the fsx.cfg. Don't start messing with this one with what I posted earlier ! The file is, as written above : FSXOptions.cfg NOT fsx.cfgYou will find it here : Users[Your user name]AppDataRoamingHiFiAS2012Options or the equivalent folder in Vista/XP
