How to have emissive receive light?

I’m working on textures that I dont really want lighting to affect for color and whiteness, but I do want the emissive materials to get dark as the sun and time of day goes dark. How can I use materials with emissive like properties to have my textures not be affected or altered but still get darker over time along with the sun?

Use a scalar collection parameter for each of your emissive material and use it as a multiplier for the emissive amount. You can control the value in level BP via the sun’s rotation.
