Spline mesh from Landscape not showing in path tracer

Not sure if anyone can help but having an issue when I switch to Path Tracer the spline mesh of my road doesn’t show. If I switch back to lit it pops back in. If I add the road static mesh to the scene manually it shows up fine so not sure if there’s any way to solve it? Everything else in the landscape seems to be working okay

I am facing the same issue, it also happens with Ocean and water body of any sort. is there any way to fix it?

The path tracer doesn’t support all engine features. You can convert spline meshes to static meshes.
