Hi

UE5.8.3 and previous vers to fake some quick road line markings and blend with the road, I just disable materials cast ray traced shadows. but since updating to 5.8.4.. just doesn’t work?

Anyone else having this issue?

\* quick work around for my spline mesh, just added a cast shadow component to my blueprint and that worked fine

Thanks
