ello!
I have this issue for a while now, it appears to be connected to sky light, If I turn it off, the effect is not so apparent. But in this particular scene turning off the skylight to 0 not solve it, it still weird looking.
I use this console command(r.HairStrands.SkyLighting 0) , but in this case it makes it to be pitch black, the hair supposed to be darker grey but not black! The hair also vibrates weirdly!
I also use theese console commands too:
r.HairStrands.SkyLighting.IntegrationType 1
r.HairStrands.SkyLighting.SampleCount 128
r.HairStrands.Voxelization.Virtual.VoxelWorldSize 1
My setup is in lumen, and I use UltraDynamic sky
Any ideas? Thanks!
