This is a very serious P3D V5.2 bug. I took the approach of uninstalling and updating the client, content, and scenery from 5.1HF1 to 5.2 and SDK.
I have reported it to Prepar3D , but no readback.
the Volumetric Clouds hide some terrain in some viewing angles.
if any good ways to fix it , i will tell there .
When flying into ENOV from outside, the gas station at the head of runway 24, a fence, a 3D grass field, many vehicles, and items in the hangar within the airport, and fire trucks, all floated in mid-air.
