Hi all! I have a reflective surface and a glowing object, that I need to render in two individual layers (layer 1: reflective surface, layer 2: glowing object) for later comping. I'd like include the glowing object's reflection in the glowing object layer (but NOT in the reflective surface layer, so that the two are completely independent of each other).

I tried making the reflective surface invisible to diffuse, but it still shows up in the glowing object's alpha channel (as a solid white alpha mask), which is not what I want. I need just the glowing object's reflection to be in the alpha.

Thank you in advance :-)
