HDRI lightning on groom (Metahuman)

Hello everyone !

I try to render characters with hair like metahumans. I Would like to use HDRI as light and background for my scene but when I use them i got render like this :


For comparison, here is the same scene with some classic lightning :


As you can see the HDRI is doing some weird reflection and doesn’t lit at all in some angles.

If anyone as encounter something similar and have a solution, maybe it’s just a trick to do with the skylight of the HDRI.

Thanks !

No one as any idea on how to solve this ?

I use CC4 characters and have the same problem. It’s even more apparent when using path tracing. At least for me. I assume it’s a bug of some kind.
