Emissive Material Glows at runtime but not in editor

I’m starting to work with emissive materials and I’ve them to glow in-game using a post-processing volume but I can’t see how they will look in the editor…my emissive material just looks like a white disk.

I’ve been doing a lot of googling and I’ve seen a lot of people with trouble with emissive materials but haven’t seen this specific issue.

Thanks
Eric
