Your welcome. As far as shader networks are concerned, I reccomend you do a google search. That might get you started. I have never messed with shader networks, so I cant really help you in that dept, unless someone here is willing to put in the time and effort. I also reccomend you know how to work the hypershade before you start adanced shading, if building your own shader is what your going for.

By the way, I thought Pure_Morning was going to explain the ILM methode of light sabre FX.
