I mean glow that is around the planet, or shaped around the asteroids. You can see it is proceduraly shaped around the asteroids for example.

Nothing comes to my mind right now, any help appreciated!

Hi @Wrymnn

you shoud try particles as child of astriud object and it moves with astroid so your glow also moves astrorid, this one is very easy way but you have to manage z depth issue with camera ppostion.
