FPS Gunflare

I have some pretty decent gunflare effect now which works with third person using sprites attached to end of gun.

I want to use the same with First Person but need to ensure the flare sprite always stays at the hud position (centre of screen basically).

I assume I need to use some kind of transform for the co-ordinates but cant get it right.

Any ideas....

Use EntityParent() -- the flare with stay in position relative to the player/HUD that way.
