render reflections separately
I am trying to render a computer with the use of multi-pass. The goal is to render reflection and specular in a separate png sequence so that I can overlay it on top of image I will put on computers screen.
When I render using render queue, I only get one png file with the whole project inside it. I was hoping for separate images, each corresponding to specular and reflection. If I go to Picture Viewer, I can indeed see the multiple passes.
What I did so far: in render settings I checked reflection and specular and tried different options in Separate materials, Separate Layers and Mode.
I feel like that I am missing something obvious here. Any idea what?
