no reduced visibility

Not sure if I'm doing something wrong or if not set up right but when metar shows 1sm visibility in FSrealWX Pro because of mist, fog or snow I can still see for ever. There is no reduced visibility.Perhaps there is something in the settings I need to adjust? Any help would be appreciated thanks.....

Which airport are you at?
Which FS 9, fsx, P3D, Xplane?
Maybe I could test it.

ksdf vis.4sm -rapl br

my ground level visibility is pretty much unlimited

sorry FSX

I went to KPIT (I am testing today som Xplane10-32).

Looked ok ... I noticed Xplane does not show snow falling in my current setup but visibility is OK.

it's been an issue with me for some time now, even if metar shows 1/2 mile vis in fog or snow. I still get unlimited ground level visibility

I went to KSDF the vis is 6sm now light rain.

Rain is not modeled .. but vis is looking correct in xplane.

KSDF-FSX-Raining outside-Vis limited = all ok here

still nothing, KIAH metar today: 221424Z 00000KT 2SM BR OVC014 18/17 A3004. in simulator FSX cloud coverage ok but visibility unlimited.In Flight Data section in FSrealWX pro wind 003/0.0KT visibility unlimited . using REX4 texture direct with FSrealWX pro as weather engine. Any ideas would be appreciated thanks.............Also just notices that fsrealwx pro shows correct visibility in flight data section for a couple seconds then turns to unlimited. I checked the weather settings in fsx weather and the visibility is set on unlimited. doesn't change to reflect the vis in fsrealwx
