UE 5 + Groom/Hair is not working properly

Hey all,
I am creating a character to test UE5, and I realized the the hair shader ignores any indirect light. So it gets super dark. Also the Scatter and Backlight from the shader doesn’t seems to be affecting anything.

I set up my scene to work with Lumen, and any shadow that hits it gets super harsh and weird.

The Skylight with HDRI doesn’t seem to affect it as well… I can boost it up, everything gets brighter, but the hair keeps dark the way it was.

Thank you.

Can you post a screenshot?

I think I’ve seen a youtube video on this exact issue and how to fix it, but I’m not totally sure.

Sure, thanks for the reply.

Left is a image of the character inside UE4, the Sky Light affects it’s color and reflection. Not sure if it is getting indirect light. But in UE 5 it is not getting skylight, nor indirect lights. Shadows gets super dark and hard.

Something I realized in UE5, the eye shader settings also doesn’t do anything, the iris mask and iris distance. Gonna test if skin transmission is working.

Here’s the video I saw. Not sure if this is related.

He goes over a few settings and what happens.
