How to use digital humans fuzz shader? Setup?

Hello ,

I imported hair splines of peach fuzz for a character’s face. I cant get the hair fuzz shader to work with it. When i turn use material with hair strands the shader itself does nothing. If i dont turn it on, the shader will not slot itself and the default hair material stays in place.

Any ideas? I managed to get the other hair shader to work with head hair and beard etc.

Thank you for your time
