This is a low poly light saber I created for a game. All of the shaping is done with a bump map. I added the glow to the blade to help visualize how it would look in game.
My main reason for creating this was to use all bump maps. I plan on uploading a modeled light saber at some point later. My main thought was to design a lightsaber that would require very little resources in a game. No it is not the most pretty one out there but it sure beats the ones they used in Jedi Knight Dark Forces 2 :) (a game made around 1995 if I remember correctly).
The glow is created by the composting nodes. I am not sure what you would need to do to get it to glow in the blender game engine. Most of what I have done with games had been with irrlicht. Like I said in the description, I used the glow effect to help you visualize how it could look in a game :).
You could of done a better low poly lightsaber..& u could of done some modeling to the handel
