Created a flickering material for geometry... how to link flickering to a light?

how about having the control from within a blueprint for both. basically have a blueprint which could be the video screen or the level blueprint set a scalar parameter for the material and set the lights intensity at the same time. then they would match very well.

I have a material for a video screen that’s doing some flickering.

Trying to link this to a light, so the light flickers simultaneously.

Have been using “Time” input data in my materials, but this doesn’t seem to sync exactly between the light and the material (basically copied and pasted the nodes from the material for the geometry to a new light function material node).

Is there a more Global time node? Or another better approach?

I can’t use Emiss for static since the asset is dynamic.

If it matters, this project is not real-time. Short film.

Over a year later…

At the time, I didn’t think this was going to work, but it’s essentially what I ended up doing in the end! Cheers
