Testing lumen with RTX 3090 in interior scene

I’ve used hardware raytracing in lumen and maxed out all the settings
trying to achieve maximum realism and export cinematic at the highest setting possible
this is the cinematic: UNREAL ENGINE 5 LUMEN INTERIOR hardware raytracing RTX 3090 - YouTube
in the video, I have used just a LUT

as you can see there are some artifacts in the video (indirect shadow)
but overall is good


Movie render Qeue?

Other question: running the sequences at cinematic viewport produces these flickering artifacts too?

If you are using Ray traced shadows and rendering with antialiasing passes on the TAA in render movie queue, that is probably the cause of the artifacts in the shadows. You can try rendering in 4K with no AA passes to avoid the shadow artifacts and still get a good quality, or switch your raytraced shadows to the new shadow beta on project settings.
Sorry for my bad english :slight_smile:

I’m running into the exact same thing. Shadows flicker, and some aliasing. I did see in one of the live streams from Epic about Lumen, that since Lumen is designed for realtime, there are advancements needing to be done on the render queue side to optimize results. If I turn on “real-time” in my cinematic viewport it’s displaying as expected (clean, no shadow flickering) but when sending the scene to the render queue with all the console commands for high quality, it still flickers in the shadows. I’m starting to think this is a limitation of the beta at this point…
