Configuration

You can either directly measure the distance of the headset to the COR of the motion platform, or use the following method to find the proper values.

Step-by-step instructions on how to set the "Center of Rotation":

• Make a copy of the *.Mover file.
• Run FlyPT Mover with that file.
• Add "SOURCE :: JOYSTICKS" and
  • click on the white field next to "Yaw position" and move the joystick axis you want to use for Yaw until it is recognized
  • do the same for "Roll position" and "Pitch position"
• In the "POSE :: FROM MOTION" module
  • select "SOURCE :: JOYSTICKS"
  • set the "Value" for Yaw/Roll/Pitch to "Yaw/Roll/Pitch position (°)", respectively
  • set the "In gain/flip" for Yaw/Roll/Pitch to the corresponding value in the "Range" column (add a '-' sign to match the direction if necessary)
  • set the "Filter" for Yaw/Roll/Pitch to "EMALP(VALUE;500)"
• In OpenXR-MotionCompensation.ini
  set these parameters:
  [startup]
  physical_enabled = 0
  overlay_enabled = 1
  auto_activate = 1
  auto_activate_countdown = 0
  [tracker]
  type = flypt
  offset_forward = 0
  offset_down = 0
  offset_right = 0
  
• For your motion platform
  • move it to the neutral position
• In your simulation program
  • activate motion compensation (CTRL+INS)
  • turn on the overlay (CTRL+D)
  • center the cockpit position (SPACE in MSFS 2020)
  • calibrate the virtual tracker (CTRL+DEL)
  • you should now see the overlay pointers right before your eyes
  • make a full roll to the right
  • use the keys for "offset_down" (CTRL+PGDN) and "offset_up" (CTRL+PGUP) to re-center the image
  • make a full roll to the left and correct if necessary
  • make a full yaw to the right
  • use the keys for "offset_forward" (CTRL+UP) and "offset_back" (CTRL+DOWN) to re-center the image
  • make a full yaw to the left and correct if necessary
  • make a full pitch up/down to verify correct settings
  • use the keys for "offset_left" (CTRL+LEFT) and "offset_right" (CTRL+RIGHT) to center the COR (not necessary if your seat is centered to the COR of the platform)
  • save the COR data (CTRL+SHIFT+S)

• In the "OUTPUT :: Motion compensation for OVRMC" module
  • set the "Filter" for all DOFs to "EMALP(VALUE;150.000)"
