using line render and a halo for a lightsaber effect

OK I’m very new to using Unity. I’m wanting to use a line render for a halo effect with a white cylinder for a shaft to create the glow effect for a light saber. However I have no idea how to begin to set this up. I don’t know if this belongs here or not. I have no idea where to get the shaders i need or anything. I’m as new as it comes. Any help with steps would be appreciated.

Perhaps post a picture of what you want to achieve, with some more description if necessary.

What I’m after is getting the glow of a light saber working within unity as I’m working on a star wars game for my final project in School. I read in this post http://forum.unity3d.com/viewtopic.php?t=8204&highlight=lightsaber where a guy used a halo effect to achieve that glow. I’ve tried sending a pm but didn’t get a response. I’m wondering if anyone knows how it could be done.

There’s another approach which involves using several objects one inside the other with an additive shader on each. It is explained in this thread.
