I set my hat view to pan mode (F8). This way I can follow the gun tracers from start on. Yet this solution is just a help out.
Another issue on cv guns:
I would like to have an information of the reload status of the gun. When shooting in Land or Sea Mode I loose the relative position every time I pull the trigger even if no shot is released.
Alternative solution: the relative position is updated to zero only when a shot is released.
