How to implement a Halo Effect Component like Unity

I multiply 100 to emissive color. Set the material to a Sphere mesh. But the result is not desired.
I need just a simple effect like Unity. The game I was working is just a simple puzzle game. Don’t need complex effect.
Change color and size in component properties is statsified just like Unity.

Can you help me or just give some hints?
Thank you.

Thank you. I will try it.

If you’re after a simple and cheap effect you may find Billboards better do what you want.

If you draw a halo as a texture, with suitable transparency, then this would let you map it onto a plane which UE4 will turn to always face the camera. It’s an easy effect, but a usefu
