New physically based hair shader model:

I have a hair model with three textures: baseColor, Opacity & Normal map. How do I use this new hair shader model? Can someone point me in the right direction? Just a quick and dirty explanation or an example of the material nodes.

I have 4.11 installed. When I switch to hair under shader model, it turns the hair black.

Here it is if i switch back to default lit:

translucent blending does that black thing
use masked instead
