I'm just wondering if there's a way to use iclone/CC4's post effects in a scene in unity. I like the way the Contrast_D makes characters look in CC4. Is there something I'm missing perhaps in the reallusion character importer within Unity? 

Unity has a completely different rendering engine.

I was thinking that but I thought I may as well check if perhaps reallusion had something similar made for unity, thanks

Just FYI but unity has its own set of Post effects that you may find can give you a look you want
