Hello.
Lumen and foliage not a great combination. I’m wondering if there is any work around having these dark areas in dense areas.
Scene lighting is overcast. Combination of HDRI, skylight and direct light. Other picture is with skylight intensity 1 and other is with 20. If I turn of shadows the issue still remains.
Material is Two sided foliage with quite light texture.
EDIT: Well this seems to work…
Foliage is not totally supported with Lumen yet. You can disable RT on just the foliage. Or put a SSS material on them. Both of these will remove them from the Lumen scene rather than disabling HWRT for your whole project.
Maybe you can share some more information what you had in mind? SSS material gives the same results as Two sided foliage in my case.
You are right, I don’t want to disable hardware RT for my whole project.
Hmm maybe try this cvar
r.Lumen.ScreenProbeGather.ScreenTraces.HZBTraversal.SkipFoliageHits 0
