Here is a screenshot of my iClone 6 character imported into Unreal, with the example skin shaders applied:

As you can see, the skin material settings have a great result.
However, the hair still doesn't look great. Unfortunately the method used by Epic to achieve great looking hair can't be applied to hair imported from iClone 6/3DXChange 6, as far as I can tell. I'd be happy to be proven wrong though!
Has anyone worked out how to bring the visual fidelity of iClone hair up to the same standard as skin?
Or, is it simply a matter of waiting for Reallusion to develop higher quality hair content for CC2 / iClone 7?
