Hey there,

I have an issue with Lumen reflections in UE5 where they appear as soon as I look down and become black as soon as I look forward.

Anyone know how to deal with this?

Thanks in advance.

This is a bug with screen traces, I’ve also encountered this and it seems to just miraculously fix itself on occasion. If you can figure out how to reproduce it I would encourage you to submit a bug report for it.

I see, yeah I actually fixed it somewhat by playing with ‘r.Lumen.Reflections.HierarchicalScreenTraces.MaxIterations’ and ‘r.Lumen.Reflections.HierarchicalScreenTraces.UncertainTraceRelativeDepthThreshold’ in the console command. It brought back the reflections but added it’s own issues a bit.

That’s what you get working in a beta version I guess! Thanks for your reply.
