Lumen isn't working great?

Development Rendering

I was very excited by the possibilities of Lumen after some initial experiments.

But now that I'm trying do do some more "real world" projects with it, I find it's not working great... There are some dark pattern shadow artifacts that can appear on some indoor renders where light comes from a window.

Also, I find it takes a lot more time to export images with Lumen than with Path Tracing.

I'm using the latest 2023.2

Anyone else experiencing this?

Hi,

Yes, exactly the same on my side. Lumen also produces very dark shadows that are IMHO very unrealistic.

I'm also getting annoying black stripes at particular hours of the day, don't know how to avoid this.

Another problem is that in any video calculated with path tracer render, everything flickers :-( vertical black stripes
