So I've been using a technique for a little while now which is to create a map for Eccentricity on a blinn shader. This method allows me to give the illusion of fingerprints on glass, or scratches etc. This method is not a specular map since it doesn't define where things are shiny and where they are not, it simply defines where the highlight is expanded and where it it tight.. So in maya software renderer it works perfectly every time, and in the realtime viewport it also works perfectly (viewport 2.0) however, in mental ray it doesn't work at all.
So I'm left with trying to render the highlights alone in maya software and composite them after.. what I'm wondering is if someone smart might have an alternative way of doing this same thing that would work in mental ray..?
I tried with the mental ray Blinn shader but it doesn't have those properties open..
