And Uwe - no, none of my characters have hair maps, those are only in the Project M4 Hairy, F3 and D3 Hairy products.

But as you can see also in this attached render, extra hair maps aren't necessary, no fancy node settings in the MAT Room to get a different skin. Times are over when SSS washed out the original skin details like moles or hair.
