Good day.

It is possible, I know It is, but can not tell you how… but I’m not an expert on materials, reflections, etc… you should look some tutorials and learn how to do this kind of things. And, Unity 2018 hhave a lot of new features about lights / reflections / materials.

You should take a look!
