Toggle on/off the Emissive from a Material?

Hi, i have created a simple Lightmodel with a Bulb. I have set a Emissive to this Bulb. Now i created a Switch Blueprint for this Light, but the Bulb is still “on”, when i turn off the Light. Can i turn off the Emissive too with the Blueprint?

Thnx a lot…

Basically you’ll want to create a parameter in the material that controls the brightness for the emissive in the material, and in a blueprint create a dynamic material instance, and then drive that parameter.
