Metahuman hair reflecting strangely with lumen

Hi all,
I am having issues with the hair on some of my metahumans. When hitting a certain angle of light it gives off an exremely bright and shiny hair effect which shouldnt be there. I beleive it has something to with how lumen is impacting the lighting of the strands.
LODs are set to 0.
IMage with Sky light turned off -
Image with skylight (and i assume lumen lighting) on -

Ive tried almost everything in the hair settings within the metahuman.
Any advice would be greatly appreciated.

Do you have any emissive material in your scene? (Like the phone’s screen)

I had a similar problem and I “fixed” it removing the emissive material, apparently Lumen doesn’t handle it very well yet:


Thanks for the reply, unfortunately the only emmisive material seems to be the skylight. I cant find any other emmive materials. Ive had this issue in multiple projects now and just cant seem to find a fix for the shiny glowing hair

There is a setting, i think under experimental in proj settings, deep…something setting I saw earlier that mentioned it helped with hair… finish compiling shaders and ill look for it

Cast deep shadow, in the directional light (i assume other lights as well)

After looking it up Im not sure that would help but worth a try…

Hi, did you ever manage to find the solution to this? I am currently dealing with the same issue
