How to apply multiple halo or glow effects to one object?

[JackKalish]

I’m trying to create an effect like this around a sphere. It should look like rippling waves of green light emanating from the object.

So far I have tried the Halo effect, and the HighlightingSystem asset (Unity Asset Store - The Best Assets for Game Making)
But both of these allow for only one “layer” of glowing around the object. Any idea how I could go about creating multiple layers of glowing light that could radiate outwards like ripples? Is there some asset available that could do this? Do I need to write my own shader? I am new to Unity, much obliged for any advice! Thanks.

Off the top of my head, I would probably do this by creating a simple photoshop image with a spherical gradient (or maybe AI would be easier). Add transparency as the sphere gets further from the center. Then add a Quad GameObject positioned same position as your object that is to receive the effect, and make it a billboard. The center of the sphere should be hidden by your object, and the billboard will cause it to always face the camera. From a distance it will look much like a halo. You can then adjust the colors, size of rings in your photoshop/AI as needed.
