Hi, Anyone has any idea how the blue flame is created?

It seems a piece of geometry with facing ratio opacity ans some incandescence...I get similar effects in rocket motors using this technique,and renders very fast.
Edit:Some example of flame creation...may be too glowing...:wavey:

That looks freakin sweet! Thats a piece of geometry with a shader applied?

That looks cool! Do you mind sharing the scene file or shader for us to play around with?
That would be nice.
