I was landing earlier today in LPPT and the visibility was really low (I love it)
But I’ve struggled a bit to land because I only had lights and I couldn’t understand for moments were was the runway at because I couldn’t see the ground… literally…
I don’t know if it’s a known issue but I’ll leave it here!
In terms of the fog, I think that is just how it is rendered in IF. But in the photos, it looks like there are no runway or ground textures. This is usually down to an error loading scenery or a cache issue, and can be easily resolved by clearing the scenery cache in the in-app settings.
