That's just a material emission, the character has 3 different materials on him just to change his color.
All the different colors is me messing with the materials, but it still doesn't have any textures or uv's.
If you were going to use him in a 3d program like blender you just have to make sure the light material has an emission value and use a compositor to get the glow effect.
As far as a game engine though I don't really use any so I'm not sure if an emission value on the material will give you that glow effect or not.
