Black Hole / Gravity Magic VFX

Black hole / gravity magic niagara system I made in Unreal Engine 5. I don't know what it is about gravity energy, space magic, void stuffs, ect. just feeling right being black with purple. Used CGHow's nebula particle tutorial as a basis for center particle cloud. The center sphere is a basic material that uses some fresnels to control opacity and refraction. Played around with different blend modes for the accretion disk and decided on translucent as it gives a nice side profile with the sphere rendering on top.
