I am making a model of an Arc Reactor. In the model, there are some wires and a sphere with emission material, inside a glass material to create a glow effect. Now I want to make these emitting objects glow and add flares in post-processing, so I was wondering if I could Isolate the emitting objects and mask out the objects in front of it so that I can mix the two images in post processing to make the whole thing glow. Thanks.

My Final render: Final Render

Emitting surfaces only: Emission Surfaces

What I want (kind of): What I want

Also, I think that the center ball-like emitting piece will block the foreground of the render which I don't want; So what would be a good way to composite it? Thank you.

  • $\begingroup$ Why do you need to mask for a glow? Isolating via masks will likely end up with a less than ideal output. $\endgroup$ – troy_s Sep 5 '19 at 21:22
  • $\begingroup$ So what would recommend if I want to add a glow around the object? $\endgroup$ – AshKB Sep 6 '19 at 3:03

  • $\begingroup$ Simply keep the scene referred ratios, and apply a generic glow. If you need an outer ring emission, model it. $\endgroup$ – troy_s Sep 6 '19 at 8:51
  • $\begingroup$ Can you please elaborate on how can I model the outer ring emission? I have tried increasing the emission value but I loose the details. Actually I want the ring to glow but the glow should be blocked by the copper wire pieces. $\endgroup$ – AshKB Sep 6 '19 at 8:55
