Overcast Near The Horizon

Recommended Posts

Just wondering, but does anyone know if they ever came up with a fix for the overcast sky in FS002? It never meets the horizon - there is about an inch of blue or so above mountains and land. Thanks. :-wave

It can meet the horizon. The following two pics are an example. I took them from one of the FS2002 Pilot training courses. Under Learning to Fly/Intsrument/VORL.Adamson

Not quite sure that these replies work for everyone. When I bought this sim and flew for the first time, I was very disappointed with the so called overcast sky. It is just not realistic. I don't see how saying - The problem is with the maximum visibility of the sim. Since the max visibility is 150 miles, if you can see further than that when you're using the sim then that's all FS2K2 projects -is the asnwer. Maybe I am missing something. I have tried several times to get a realistic overcast sky - using real weather from Gatwick when I can clearly see overcast clouds at 1000'. But FS displays a lovely blue skyline. Even at night you get lots of lovely stars. Changing the viz has no effect what so ever, at least for me and I have tried several times. In fact I will not use the overcast setting now. How do other people overcome this? Or does it only do it for certain airports?Keith

Hi Keith,To be honest with you I have never seen a totally overcast sky where you can still have some visibilty. If there sky is not filled with haze, fog, rain, snow, etc, then you get clouds with a blue sky on the skyline. I think that it's a limitation of the program.

Hi,Yep you are probably right. But I do recall with my Old Pro Pilot 99 getting far more realistic clouds and misty bits. Pity MS couldn't have used their techniques!Keith

I think that what you are missing is when dealing with visibility, there are in fact 2 vis settings in FS2002:1) max visibilty for the rendering engine (meshes in the distance are clipped past this limit). Set in the display settings2) atmospheric visibility set in the weather panel.with 2), you can effectively smooth the graphics from the cloud layer to the ground with atmospheric haze.Hope this helps!

Ok folks, sounds good. But I still don't know how setting another cloud level helps make the overall cloud layer drop to the horizon? Nor do I understand how in the pictures we have the cloud at the horizon?I am off to try all these things out and see what happens.How do other people get on with this?Keith

Just set your max vis to 60 mi and you'll be in great shape.

You have to be smart enough to look at the weather settings for the example pics. At least I gave the scenario where the pics came from. It just takes a little research on ones part!L.Adamson

go to advanced weather options, select cirrus, on the graph drag it all the way down to ground level and up to 15,000 feet, you can make it light blue to white depending on level of cloud coverage.

Jase439,Tried that but it didn't help (actually made no difference whatsoever). A I am beginning to think this is just a "feature" that we will have to learn to live with in FS2K when the weather is broken to overcast and the vis is more than a few miles.The other solutions involve playing around with the weather but for those of us who use FSMETEO (or other live weather programs) that is not an option.Too bad. It really detracts from the visual representation in my opinion.Kevin in CYOW.

Thanks for that. But can you have clouds overlapping each other? For instance can I have a layer of cumulus at say 3000 to 7000 with overcast set, and then have a layer of cirrus from ground to 3500 or whatever? And I still have to say tou should not need to do this. If the setting is overcast than its overcast. And that is that. I have tried all the various suggestions, viz to 60 max, weather set to 10 miles viz, etc and still I get this blue sky. I will try the cirrus, but I have to say, for me it makes flying in overcast skys look completely unrealistic.Keith

This sounds like the answer, finally. Thanks. Here's an idea...I'll try this out, and if it works for me, I'll write to Pete Dowson and ask if he can incorporate something similar into a future version of FSUIPC.Matt

I agree...the above pictures seem more appropriate for flying in forest fire conditions like those earlier this summer. The effect shown above is a bit more pleasing if you extend your surface visibility out to about 20 miles or so - it doesn't look quite so "smokey".And no, you can't overlap clouds.The heart of the issue here is that while logically, the FS world is a sphere...on your screen, it's flat as a board. There is no curvature of the earth. Earth and sky are parallel to one another. It's alot less expensive computationally to texture a plane than a hemisphere - which is probably why it was done this way. So I think what you're seeing here is the point at which the "sky plane" meets the far clipping plane (the limits of the imaginary box that is your virtual world - everything outside this box is never rendered).Certainly there are other ways they could have achieved the desired effect - other sims have (I can think of a couple inexpensive techniques I would probably have used). But when you're dealing with a relatively high deck of overcast with nothing undeneath (especially in 10+ SM visibility conditions) you're inevitably stuck with blue sky unless you employ one of these "tricks".J

But I'm finding (thanks to some of the above posts) that if you select cirrus 7/8 coverage from ground level up, and then put in a cirrus overcast layer directly above this first layer, you get a well-defined cloud ceiling skimming by above the plane, plus no more blue out towards the horizon.For me, this is very convincing. Seems more like an overcast day rather than the forest fire effect you would get with just the first (ground up) cirrus layer alone.

I did the same thing with a stratus overcast layer and cirrus 1/8 coverage from the ground up...it does work, it's not optimal, but it's better than solid blue. And as I mentioned in my previous post - the effect is "less smokey" if you elect for a lighter cirrus layer and allow your visibility be extended to around 20-30 miles.Unfortunately, FS Meteo won't give this to you, nor will ActiveSky as far as I'm aware. Additionally, if you have FSSW installed, your cloud thickness is limited to 7000' (as per Chris Willis' instructions)...so if you have a high cloud deck and want to fill in the cloud area below it, you have to create multiple cirrus layers between the ground and the cloud deck in inrements of 7000 (or whatever you've set as your maximum cloud thickness in FSUIPC).For those who enjoy hand programming their weather environments, I suppose this is an acceptable workaround - but I would venture that most use a Real Weather environment.Cheers,J

Jase439,Uh, Yep. Radeon 7500. Oh, oh. Is this a known issue with the card?Kevin in CYOW

I'm not sure if the 7500 is affected by this or not, but Microsoft has a KB article about ATI incompatibilities and FS2K2. I don't recall the specifics or the exact symptoms described in this article, but it has to do with areas of fog/haze effects on the horizon showing up as solid blue on ATI cards. I think some ATI users on here have called it "the blue curtain effect" :)I'm just wondering if this is what you're fighting.JPS. I don't think the new 9700 has this problem.

Hi, " you have FSSW installed, your cloud thickness is limited to 7000'"Fsw clouds are not limited in clouds height,you can set them at any height altitude, only advice to reduce the anomalies in fs2002 stretched clouds when they are more then 15 000 feet in height.ThanksChris Willis[link:fsw.simflight.com/FSWMenuFsSim.html]Clouds And Addons For MsFshttp://fsw.simflight.com/fsw.jpg
