arkonthe read me says how to do this:
In HudLayout.res you control which crosshair you want to use. To change it, find "fogCrosshair" By default KNHUD comes with the crosshair "1". Look at the Crosshairs.png provided and change the value of "labeltext" to the value of the crosshair you want.
Thanks, but i am at another problem. It is not perfectly centered. I've read the readme and it isn't there. How do I change the position?
