Sequencing an emissive material along blueprint instances

[ClockworkOcean]

Dear community,

I am a newbie to UE4 and I need your help.

I am trying to use a mesh asset which has been converted into a blueprint actor, to create a chase light effect between the actor-instances.

I set up the emissive material to loop the light on/off, but right now all actors turn on/off at the same time. Can I sequence the animation in delay between the actor instances without duplicating the material and still using the same single blueprint ?
I know about “Get All Actors Of Class” but I’m not exactly sure how to use it to get that effect.

Moreover I would want to control that effect in a way that I could sync it to audio, play it faster/slower - change it from linear sequence to random and more…is that doable?

I somehow can’t upload images here so here are the screenshots via dropbox: Scene: https://www.dropbox.com/s/8nurz46qwf…Scene.jpg?dl=0 Blueprint of the emissive material: https://www.dropbox.com/s/149z6pmw70…Print.jpg?dl=0

Thank you very much in advance

Elad.

Are you saying you want to light them up in sequence?
