Can you render a light layer with movie render queue?

Hello, I’m trying to compose a “back to beauty” render, splitting the lighting and reflections and re-composing them in (photoshop/nuke). I’ve done great but I’m only missing my specular highlights, I need only my highlights, preferably with alpha but not necessary.

I’m using movie render queue, but if there is anyway to only get the highlights that would be great :slight_smile:
