Grass rendering with Path Tracer is weird please help

image
This happened when I turned the path tracer on, but I fixed it with the console command ‘r.RayTracing.Geometry.InstancedStaticMeshes.Culling 0’.
However, the texture? the shadow? of the grass changed completely,


This is the grass before I used the console command(and the intended look)

and this is after.
I also used the console command ‘r.RayTracing.Geometry.InstancedStaticMeshes.CullAngle 1’
and this did increase the distance that the grass is rendered, but every time the camera moves the shadow of the grass changes drastically making it unable to use as a reel.
If someone knows how to fix this please share your knowledge. It’ll be great help.
