Severe ghosting in VR when using Lumen — baked lighting looks perfect, but Lumen causes heavy ghosting

[SupportiveEntity]

Hey there @Kye1002!

Lumen in VR is still a bit of a work in progress, and it seems you’ve pulled most of the levers that we can pull, but the screen space probing portion is what’s likely causing the ghosting, especially with stereo rendering if you aren’t using any other temporal effects.

Try playing with more of the ScreenProbeGather settings, one I’ve gotten use out of is the temporal probe history weight, it may mitigate the issue (but won’t resolve it fully):

r.Lumen.ScreenProbeGather.TemporalFilterProbes.HistoryWeight

Lumen with Hair Strands is ghostier than Hair Cards

It’s surface cache right now, intended for a game. I’m trying to keep it somewhat performant (by Lumen’s standards, at least) in hopes that it’ll work on less top-of-the-line machines. And there is indeed a skylight with some leaking in the lumen settings. The level also contains a distant light, but it is currently occluded by the room. Also an update: I’ve had good luck reducing ghosting with console vars in the region of r.Lumen.ScreenProbeGather.Temporal.BlahBlahBlah My notes were written…
