How can I reset a vector parameter?

I have a door with a flashing light.
It’s a simple black to white VectorParameter multiply over an emissive texture.

I’ve successfully volume triggered that vector parameter in a blueprinted material instance for the flashing light effect.

Now I’d like to reset it.Or turn it back to black.

Anyone know how this is done?

Could someone on the Epic support team field this one please.

This seems like you have all of the tools you need to handle this. What event do you expect to set it back to black? Are you wanting to use a timer, a volume, etc?

If i understand your issue it should be as simple as setting the parameter to black again based on an event/timer.

My apologies, it was my user error. Case closed
