Some questions about hair material.

I found that the UE4 just support deferred rendering until it has lost a lot of good shading model such as anisotropy.
Even it does not support the spectacular on transparent material.
But I got a sample by accident,it use the emissive and Camerafactor to give it a “highlight” on its Dragonfly wings.
I am trying to do that on hair material to give transparent hair highlight.And is there someone who succeed in this kind of experiment and like to share that?
As for the anisotropic effect I have no idea too╮(╯_╰)╭
Does some one know how to make it perfect~?
