try to check postprocess - lumen global illumination - rize value of lumen scene view distance and max trace distance
For me, it doesn’t help if I rise those values from 1000000.0 to 2000000.0
UE 5.2
If you have this problem with raytraced shadows and grass foliage, try out r.RayTracing.Culling.PerInstance 0 to disable culling shadows for foliage instances.
