Lens Flare- Increased Length (not width)

[EchoRanger449]

I'm using uzi9mm's sword model in first person- I didn't PMI the level since it's for trial.

Because I'm using the first person model for both the first and third person models, the lens flare shows up on both.

Now the first person view makes the lens flare look good, but if I want to do the same for the third person model, I should increase the length of the flare (forward) without increasing it's radius.

increasing the horizontal glare has just given me a wider flare, and it doesn't make it any longer. I've been looking at the other radius values in the plasma lens flare tag, but they all see to only affect the width. Please post if you've found anything that may help, or if you have an idea. Thanks!

*Edit: I have concluded that length cannot be adjusted- the radius is merely a perspective thing*
