Just found out that if I change light on my face, hair stayed exactly the same.

The hair are exactly the same color/intensity, only the skull has some shadow.
(yeah you can compare both hair, they are exactly the same pixel color)

I just have some black planes above my character to block the light.
The face take the shadow but not the hair.

Why does my lighting does not affect the hair ?

Worked! Thank you!

Up ! Anymore help for the reddish eyelashes problem and wrong reflection on hair ? :slight_smile:
(only with r.HairStrands.SkyLighting.IntegrationType 1)

Iā€™d try increase the melanin of the hair material instead.

The only fix I have found that worked, finally, was to go into the Metahuman parent hair material graph (M_hair_v4 in my case), and make sure your SetMaterialAttributes output node is connected to the shader listed in the Feature Level Switch that you are actually using in your preview device profile in the project editor settings. I am on a Mac using SM6 and after connecting the node to SM6 all hair problems are gone. Default is ES3_1
