Metahuman hair glows, and appears white

:smiley: 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!:smiley: 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!

I found out If I go backwards from the scene the white hair goes away, and the normal one comes in place!

Not really, i just colored the hair in every scene, but its tedious

It seems I found solution. You can turn off the skylight for hair by r.Hairstrands.Skylighting 0. Or you can change the lighting technique for hair with r.HairStrands.SkyLighting.IntegrationType 2. For more details, see section Environment Lighting at the link.

I have the same problem; it seems to be some kind of LOD issue.

I found the solution on this post

Just search in the Metahuman folder a material called “MF_Hair_SaltAndPeper” and inside change the “Hair Cards” multiplay node from 1.08 to 0.08
