Secondary Specular Lobe skin shader/translucency

Hello! I was wondering is there’s any way of creating a secondary specular using the skin shader provided by the “photorealistic Human” Project.
I see at the end of the shader a Material Blend, so i thought it was possible, but it seems i cannot create the right material function to add a secondary spec to the skin.
Also i was wondering if there’s any way to create translucency/backscatter Effect within UE4.
Thanks a lot :slight_smile:
