I’m not sure if its possible to have an emissive media material emit real time light. You can bake emissive static lighting, but that’s for something that would never change, so that doesn’t help you much. I have no idea if you can integrate it into real time dynamic solutions such as Nvidia VXGI or Light Propogation Volumes. With your current material setup, why not just plug the base texture into both the base color and the emissive slot, rather than that white color you have currently. Maybe that will give you something closer to what you are looking for
