Controlling light intensity with sin wave

Hi, total newcomer to UE, coming from video production background.

I want to control the intensity of a light source with modulators, such as a sine wave. However, I can’t figure it out, or find a tutorial for UE5 (things seem to have changed since UE4).

I have my spotlight in a blueprint, but I can’t figure out how to configure the nodes.

As a starting point I’d like to get the light intensity rising and falling. From there I’m sure I can figure more out.

Any pointers gratefully received!

You can use a timeline and draw a sine wave type thing in the curve window.

Thanks - I’m using keyframes for now, but I’d like to get more programmatic with controlling multiple lights in continuously building and modulating arcs (think light show with modular synth controls).

I’m making a video as my first output with Unreal, but this will hopefully lead to virtual environments where blueprints will react to users. Using control signal generators seems a good step to learn.

Just a thought, but emissive materials can function as lights, and I know the Material Editor has sine wave functions. What about using an emissive material? If you look up Ben Cloward on You Tube, he has a lot of advanced tutorials on these sorts of things.
