I was currently working on rendering this robot with toonshading and glowing eyes.The glow is present on regular render (maya software,hardware,mental ray.etc), but when i switch to rendering with maya vector (for the toonshading effect) the glow in the eyes dissapears . Is there a way to keep the glow of the material shader and still apply toonshading for the rest? here is the pic of both renders.

If anyone has any hints, it would greatly be appreciated. thanks for reading.
