Hello guys.
I would like to create something simmilar like this in Eve Online - Erebus firing DD weapon.
I am trying to create that weapon charging animation.

Currently what I was able to create is this: https://www.youtube.com/watch?v=4Fg1gt9kV0Q

I used a cone and a spot light.
Animated the texture on the cone via UV offset moving. And spot light animation was done via intensity and Glow and Halo effect.

But I would love to create that ripple / charging effect you see on the video. When those circles are moving to the center from the outer part. How can I achieve this ?

Thank you for your support in advance
