This pretty much depends on the area you are flying through. I don’t really know and have experienced the same issue you have. All I know, is that Infinite Flight depends on real world METARS that changes every so often per region.
Fog should be visible somewhere. Try flying around nearby mountain ranges more often and hopefully you will see the fog effect along these areas.
I haven’t seen fog in a while, too. But, I have brought this up in the not-so-distant past with the team, and it is in fact working. I guess you just need to look harder to find it :)
Fog is very hard to come by at least in my experience. Wish it would render better from higher altitudes because its a bit weird when you fly above a fog layer and it magically disappears and now its clear below you.
Took this picture of the flight I did just now, what I realized is that in the replay the fog was more consistent and it was displayed the complete time. But when I was flying it was disappearing suddenly, surely something developers should improve in the future.
I had a problem seeing fog when my graphic settings were medium or low. If your device can manage high try that. It works for me. By the same token, I haven’t seen much of it in a while too.
Yeah, I’ve noticed issues with it as well. Spawned at an airport with very low vis. Spawned next door to fly in (practice ILS approaches) and the fog had gone away. METAR still showed heavy fog…
I believe Laura mentioned this some time ago. If it wasn’t her, it was one of the developers. It was definitely during a livestream so either the YouTube one or during one of the recent flight sim conventions.
If I can find the time to search for it, I’ll be sure to link.
