How to spawn Niagara lights from a BP in a sequencer?

[STVinMotion]

Hi fellas, I’m using a Niagara system to cast lights with shadows (it’s an experimental feature) - w/ point light component render inside a blueprint.

It works well in Gameplay but I can’t make it work in the Sequencer.
I understand that particles should be added to sequences with “Particle toggle track” but since it’s a BP there no such option. The fire flames start automatically but there no light being spawned.

Here’s how it looks in sequencer and in gameplay:

Thanks!

What happens of you make a custom event and start the system manually with it, then call the event from sequencer?
