Im not sure too, see this picture. The circles are too same, but how to move it up and down? Ctrl+9 , Ctrl+0 (keys for resize a circle) are for HUD Modes (knob start running).
I will try another tests.
I tryed according the manual set HUD position (so, shooting line too).
1/ First:
<Collimate>0</Collimate>
<!-- VC HUD collimation. 1-yes, 0-no (1). -->
<TestFrame>1</TestFrame>
<!-- HUD test pattern. 1-yes, 0-no (0). -->
2/<CollimationData>0.0,14.01,3.358,0.307</CollimationData>
looks like this:
3/ next I change position for:
<CollimationData>0.0,14.01,
1.358,0.307</CollimationData>
for test and no any changes of HUD.
For me better tool if in the future will be add small pop-up with this tests and arrows for calibration of HUD (arrows for move), save option in CSWeapon.xml document. Next You will Restart the sim and will be ok. Simple tool
