Actually, it's very simple!
Go into tools, and then into Object Maker. Load what ever object you want being glowy. Click on Effect Maker (or something like that, too lazy to check xD), then into the last tab marked "Lights". Choose whatever color you'd like to be shining on your character, then press "Add New" or whatever it says, and position it wherever you want it. Save the object, and tada! :3 Hope this helps! (I can provide pictures if you want)
