I can only think of for like the cars lights etc kind of thing which you can add an animatio node to the character and add a lens flare png image and make it additive then arrange its position in X,Y,Z settings.
Hey man, If you higher the 3D Model's Incandescence then you might get a little bit of glow there but i think it wont be enough for your taste if you really are going for that *Glow* thingy, What else you can do is have a PNG of Glow like a Blurry White ball you can create in Photoshop and drag that in your project. it will help you get more ideas on how to achieve something like that.
So I couldn't find an answer for adding a glow to things. Tried a lot of things, and a lot of those failed. The answer is simple. Add a point light to your scene. The drag it on top of the character or 3d model you want to glow. and center them up! Works a treat for me!
