UE5 Path Tracer black culling issue when enabled on the City Sample project

Hello everyone!

I’m experimenting issues when I turn on the Path Tracer on the Epic Games City Sample project. When It’s on, far mesh are culled or renderred black.
It’s probably not an issue since the Path Tracer works fine on my other projects.
Do you know what causes this issue and how I can fix it?

I documented this in a video here:

Thank you for your answers and have a nice day!

Hi guys I had same problem…is this casing by Path tracer doesn’t support HLOD ?

@Dejvvo @ZendrisStudio Try this one see if that does the trick

r.RayTracing.Geometry.InstancedStaticMeshes.Culling 0

and potentially this one too r.raytracing.culling 0

we had to do this on this sample scene Hillside Sample in UE Feature Samples - UE Marketplace in this sample scene we had a similar issue with the glass and other ISMs and HISMs
