You know, glowing is generally something that is done in post. For example, the light sabers are all done in post. 

To get the glow you need some sort of scattering, some particles in the atmosphere that create the glow. You might try adding the fog prop and setting it to the minimum. Add your glowing object inside the fog and make it emit light. That might do the trick.

In Reality there is a much finer control of the volumes. The new Lux volumes are supported completely and in a rather fun way. In fact we are preparing some promos to show them. 

In the meantime, though, use the fog prop with scattering set at the minimum. See if it works.

Cheers.
