Background plate without light interaction

How do you go about creating a “non” interactive background?
In my scene I have a sphere with a texture set to emissive to cast light based on that image. I don’t want any Unreal lights/environments interacting with it. It should be as seen in the “unlit” mode of unreal. The problem right now is that my image is way to bright. Must I create two different meshes with two different materials, one emissive and another a “normal” one. Or is there a better way?

Have you tried the settings under “Material Property Overrides” in your material instance?
