How to interpolate emissive color on material?

I’m looking for a way to interpolate the emissive color on material, depending on situations.

ei. interpolate the emissive color from “yellow” to “black” on death.

I could not find any function to get the color from material in blueprint.

You need to make a material instance so you can control the color of the emmissve from BP. Then in the BP, use a timeline controlling the parameter you’ve setup.
