    Hi,
    Sorry I have searched but can't find the answer.

    I managed to align vive controllers and vive tracker to the HP Reverb space and controllers using OpenVR Space Calibrator.
    Everything works nicely:)

    I then go to OpenVR input emulator to set my tracker as the motion compensator.
    It is in the correct XYZ from the origin position and the tracker moves in the correct direction but the movement in space of the tracker is much larger than the actual real tracker movement.
    It doesn't follow the actual position of the tracker, more like 2-3 times the actual tracker movement.

    This happens only when I select the tracker as the motion compensator.

    Anyone has any experience to solve this?

    So close to find a motion compensation for my P3 DOF Reality rig with the Reverb. Vive setup worked great but the visuals in the Reverb is amazing compared.

    Wish you all a happy Christmas and a happy new year!

    UPDATE 2020-01-22 (Ok setup, not great)
    Tested using DCS + SteamVR Beta + Windows mixed reality beta.

    1. Mount the WMR controller as picture below. (I use foaming for damping)
    20200113_183127.jpg
    2. Start SteamVR and startup the game.
    3. Setup OVRIE: Select the WMR controller installed in front of your seat as "Motion Compensation"-device.

    Issue1: When looking away from controller picture could jump.
    Short look forward resets the view

    Issue2: WMR controller falls to sleep.
    Wiggle the controller and it wakes up again
    (Keep the controller alive is a solution but I haven't found a way that works yet)

    <<<---------------->>>

    BELOW USING VIVE TRACKER (Fails randomly)

    Ok, my progress so far.

    To get the correct motion compensation I have tried to move the WMR HMD (Reverb) to match the Vive Lighthouses.
    This makes the rotation center position of the Vive Tracker rotate correctly when selected as the motion compensation unit.

    1. I do not match WMR Space in OPVSC (OpenVR Space Calibrator) with the Vive tracker or controllers.
    2. Select the Vive tracker in the OPVIE (OpenVR Input Element) as the motion compensator.
    3. Select the WMR HMD and adjust the position using "DRIVER OFFSET" to match the Vive Lighthouses + Tracker. (Tricky but after som positioning I use the Vive Controlls to adjust the menu as WMR Controllers move further away)
    4. Go back and "Save" the profile.


    Problems:
    I tested this with DCS but when starting DCS from within WMR menu it greys out.
    Could be something with the WMR HMD position that corrupts SteamVR.
    At least the motion compensation is getting more realistic.
    I will continue tweaking and update this thread as more findings are made.

    I'm eagerly awaiting your next post as I have a reverb with a dof reality set and getting sorta fed up with no good solution.

    Well it's a tough problem to solve.

    I think the only way is to make version of the OPVRIE that just cancell the motion from the rig correctly with WMR.

    OPVRIE is not reading the motion of the WMR and the VIVE tracker correctly when used together in motion compensation.

    The movement of the vive axle point and the wmr axle point when compensation is selected is not alignt and this makes the compensation fail.

    When not using the compensation the tracker moves correct in space.

    Should be an easy fix for a programmer.

    There is a thread looking to finance a programmer to fix the issue. I think that's our only hope.
