i have just installed REX and noticed a problem with the depiction of a haze/fog layer at low altitudes. i use fsx user-defined weather to create a fog layer up till 3000ft. as i fly above the fog layer, the fog layer just disappear suddenly and i can see the ground below clearly. when i descend below 3000ft again, i am suddenly engulfed in thick fog again.

That problem is fixed with Active Sky Advanced. Look at the link below. I bought it and it fixed that haze problem for me, plus its a great weather program to use aside from that fact.http://www2.hifisim.com/node/3

thanks all for the help :)i have narrowed down the source of the problem.

thanks all for the help :)i have narrowed down the source of the problem. if i used all REX textures except for clouds and sky, the ground fog layer will not disappear as i climb higher, but the transition is still a bit harsh. will try ASA one day to see if it will smooth out the fog layer. but i still miss the nice cloud textures by REX.. i wonder if it's a known bug... hope it's solved in REX 2.0

This is a much discussed topic over on the REX forums. Many people (including myself) have a problem with the REX fog layer dissapearing between ~2800 to ~3500 feet. The gentleman at REX have stated that this is a common phenomenon and will be fixed with REX 2.0.

Hi: Can you provide details on how you set up in FSX your fog/haze layer to 3000 ft? I have been experimenting with this and was curious how you do yours? Or for that matter anyone who wants to chime in. Appreciate any suggestions. Thanks, Al

In the FSX Weather menu, there's an Advanced Weather button. Click on that and you see the user interface to create your own weather. There are tabs on the top of the screen, clouds, temperature, humidity and visibility, if memory serves. Visibility is the one you want. Set up a new layer from 0-3000 feet and dial down the visibility in that layer, and away you go. It looks very much computer rendered, so I will throw in a new cloud layer (stratus looks good) at 3000-3500, with full cloud density. That helps a bit. Jeff ShylukSenior Staff ReviewerAVSIM

Thank you Jeff: I tried your suggestion and things look pretty good. I made my stratus 3000-4000. My one question is, as you are going through 3000 feet, it looks like a "white blanket" covering the earth. Do you have any recommendations to "doctor" this up to minimize the white blanket effect? Thanks again, Al

I'm not entirely sure what effect you are trying for. I guess I assuming you want full heavy fog. The big trouble is that you will see a very sharp line that divides fog from clear, regardless of the intensity of the fog. Manually adjusting the weather is mostly making sleight-of-hand adjustments to hide the seams. I really only get into it for making screenshots and maybe a few specific tests for Reviews.The first trick is to hide the seams with stratus clouds. Another trick is to put a visibility layer on top of the visibility layer. Say the bottom layer has 1/8 mile visibility. On top of that put a layer that has maybe a mile, then on top of that a layer that has ten miles, and so on. For the best aesthetic effect, I don't let the visibility extent past 60 miles. Throw some clouds in whenever you start to see rendering seams. Your mileage may vary, of course. One last trick is to fly at dawn or dusk. Avoid high noon. Jeff ShylukSenior Staff ReviewerAVSIM

Thanks Jeff for your help. Will just play around with different settings and see what looks best for me. Al

I believe that when using ASA you can still use REX textures. ASA is the weather engine and will load the texture sets that you have saved in REX. I use FEX and ASA just uses the textures that I have saved. HIFI also has a program called X graphics that changes the cloud textures and water textures as well as others like airport environment and sun and moon ect. I have used this as well. What I usually do is I install the texture set I want and then I start FEX and overwrite the textures I don't want. Textures can be turned off in FEX or X graphics so you can pick and choose. If I am wrong, someone may correct me if they wish. All I am saying is that if I understand your post right, you don't have to give up you nice REX cloud textures for ASA, ASA will in fact complement them.

i have got ASA and it really greatly improves the simulation of weather in fsx. however the haze layer disappearing issue still remains if i used the cloud textures from REX. as Mavrocket had mentioned earlier it is a REX bug. will try out FEX some day as i heard that some people prefer its cloud textures over REX, but for water textures REX is still the best out there imo.

Thanks Paul: That link is very helpful. Al

Sorry about dredging up this topic, but I'm having the same problem as the OP. I like to fly realtime weather in San Francisco bay area (USA), where I live, and it really bites the immersion when you get up above the fog/overcast layer (~2500ft) and suddenly everything below you become sparkling clear. On the REX site I've found a 'solution' posted, by a REX admin, that does not work. His attitude about this problem is "sorry something is broken and there is no way for us to fix it, so don't bother us anymore about it", though as posted above if you strip off the REX cloud/sky textures you get that fog layer below you back but it looks really lame unless you manually dress it up, which completely negates the convenience of realtime weather (and for owning REX for that matter). As for others out there using FEX, are you also seeing this fog/visibility problem? Any other advice/wisdom beyond what was already posted in this topic?Thanks for reading,
