    With thanos controller; this image here which I got from page 1;SIMHUB MOTION FOR SMC3

    Why can you not change the actuator roles; to surge , sway etc
    it only allows you to choose; front left; front right, rear left, rear right.
    Simhub is so limited that if you have your bespoke rig, you cannot use the software for motion.

    but would be good to use it for just virtual tracker only, (motion comp)

    I'd imagine as long as it doesn't effect tracking/line of sight.

    i installed openxr and all of it's components.
    in openxr explorer everything shows it is installed correctley
    in reg edit it shows that motioncompensation layer is enable and again in steamVR is also showing enabled and steamvr is forced to run pimax openxr.
    openxr-motion compensation.ini file set to "controller" as using controller with pimax crystal light.

    only problem is and it is a big one lol
    i cannot activate motion compensation using thekeyboard shortcuts.
    i do not hear the "countdown" infact none of it seems to work from the keyboard.
    runnung automobilsta 2 which is openxr game.

    can someone help me. freshly installed computer, not much other programs running apart from simtools, pimax play obviously.

    absolutley shocking. i got this working and soon as I left the pits. I was almost vommiting. The Nausea was off the chart. First of all it wasnt motion compensating at all. Infact it was even the opposite. The controller was mounted securly just like in the vid (). The motion was super smooth but it was doing some of the most strange back to front (you couldnt even put it into words) some sort of halucination effect. If anyone was to try this as its first VR experience, they would probably never dare go back to VR. I made it worse going down to KFC thinking about of food would help me recover....

    mate what angles does your rig achieve?
    i am now trying out motion compensation with pimax crystal light with the faceplate and i am feeling sick after 5 seconds . its unbearable. am i doing something with the tracker position?
    It sometimes feels as it it it trying to do "everything backwards"

    I don’t know with pimax ,I never use it … if you use a controller as motion detector try to use the filter ctrl + \. U can also increase it but I don’t remember the shortcut
