Export to Unity, causing white patches in beard

Hi there.
My beards look great in Character Creator 5. When I convert to game base, export to unity (LOD0), i get white patches in the beards. Wondering if you might know the magic trick to fix? See my screenshot. I have tried every possible export setting and CC Importer tweaks. I am sure this has to be a common thing.
Thanks!

Hi Mrnations,

Were you able to use the Unity Auto Setup for this?
