Hey! I just tried adding Bloom to a test scene and it seems to work okay for me, so there must be something else going on here! Are you able to share more details about how you've set up your CRT and Bloom effects so I can try and find out if there's a more specific problem? Maybe there's just certain settings that break it that I wasn't aware of.

Upon further inspection (And realising that Bloom is in one of the test scenes), you're right. Bloom does work, it's just the glow (Material Emissions) that disappears. My bad.
So I guess to rephrase my original question, is there a way to bring back the Emission Glow?

Edit: The particles themselves are shuriken particles, the material is just the standard URP particle material.
