Luminance Map

Hi Guys,

I'm new to this forum, i hope you all are doing great. I managed to learn many things in here. Thank you all.

My Question:
I created some models for an upcoming shortfilm, but i'm stuck on a small problem. One model is a turbine, which outputs some light-effects, created with luminance-materials.
Most part of the turbine is reflective and has e pretty strong bump-map (scratches, carbonresidue), and reflects the luminance pretty nice. What i need is a multi-pass image, which contains the luminance-channel. This is rather simple, by clicking the "material luminance" checkbox.

How on earth do i get the reflections of said luminance material on other objects rendered out with that? I need this for glow-effects and lensflares, since it will be a sci-fi-shorfilm.

What i need: Black Screen (all other materials with luminance, except for the one i want are disabled) with said luminance, including it's reflections on other surfaces.

Is this somehow possible?

Thanks in advance, have a nice one!
