I know I know, its the same old time after time answered question... but I'm ripping my hair out over it (and its a lot of hair) after looking up all the tutorials I can find, and looking through the forum messages, and none working completely satisfactorily... I am trying to get a decent transmap for an eyelash so I don't have to postwork it in... is it possible not to make Mike not look like he's got falsies on... ugh... please :)) anyway here's a render of what I'm dealing with and my shader tree.
