This is the OpenKneeboard alternative to my other augmented reality solution for the F/A-18C with the WinWing setup found here: https://www.digitalcombatsimulator.com/en/files/3344962/
Using the Quest 3 you can add this png to open kneeboard. It will then act as a mask for the MFDs and UFC.
My settings in open kneeboard are:
kneeboard width limit: 0,63
height limit: 1.00
roll and yaw: 0
pitch: 90°
Horizontal and Vertical target size 1.25x
