Black shadows at distance with Lumen

Development Rendering

1

There is some kind of border at some distance from the camera, after which black shadows begin.
Standard level (File → New level → Basic), Lumen is on. There is no such thing with Lumen turned off. Could this be due to the video card (GTX 1650 Super)? UE 5.3.2

It was because I use AO with Lumen, in DefaultEngine.ini:

[SystemSettings]
r.Lumen.DiffuseIndirect.SSAO=1
r.Lumen.ScreenProbeGather.ShortRangeAO=0

Set r.Lumen.ScreenProbeGather.ShortRangeAO=1 fixed it, but it disables AO with Lumen :frowning:
