Adding Luminescence to shirt skin

I am working on a shirt skin that I want to add a glow to, I have made an emission map and added it to the material, and turned on the emission box. When I bundle it and put it in the game nothing happens. How do I add luminescence to the shirt in unity so that it works when properly bundled?

The folder with the clothing item also needs to texture called “Emission”. The texture that applies to the player is not the same as the material for the item that can be found in the world.

So I just need to put my luminescence map into the folder and call it Emission?
