    The first version of the OpenVR-InputEmulator to include motion cancellation has just been released and needs testing.

    It works by attaching a controller/tracker on the motion platform, and then setting the center of the motion platform in the SteamVR dashboard overlay. It's largely untested because the developer does not have a motion platform.

    As we are the main beneficiaries of motion cancellation being added to the OpenVR-InputEmulator we can help out by testing, particularly on large axis rigs using VR, such as those of @SeatTime, @SilentChill, @kermitkong, @Trip Rodriguez, on complex rigs using alternate HMDs like @Pit's, plus by anyone else who has a VR HMD and motion rig.

    Download the OpenVR-InputEmulator here: https://github.com/matzman666/OpenVR-InputEmulator/releases

    Once installed you can access the OpenVR-InputEmulator from the SteamVR dashboard menu.

    Please provide feedback to the dev here: https://github.com/matzman666/OpenVR-InputEmulator/issues/4#issuecomment-299575175

    For those with 3D printers it would be helpful to come up with and share some controller mounts. A Vive tracking puck is ultimately a simple way to go for a permanently mounted tracker: https://www.vive.com/us/vive-tracker/

    @noorbeast - Rift users will want to mount their camera sensor stationary and off their platform, and everyone will want to mount the platform tracker close to their head for most accurate motion cancellation, won't they?

    Yes, the whole point of motion cancellation is to have the cameras/base stations off the rig.

    We need to test regarding ideal placement but yes I am presuming close to the head should be good.

    I'll definitely be watching how this goes. Wish my rig was ready. Sigh.

    Can't wait to hear people's impressions.

    Very useful, @noorbeast. I have read that's for HTC Vive only, "the OpenVR driver hooks into the HTC Vive lighthouse driver and allows to modify any pose updates or button/axis events coming from the Vive controllers before they reach the OpenVR runtime".

    https://github.com/matzman666/OpenVR-InputEmulator/blob/master/Readme.md

    ADDENDUM: I'm obviously wrong , the driver is used by the hack only to get it working - I'll check this out later

    Awesome news I hope it works :)

    I had a HDD failure on my gaming PC and just reinstalling windows so hopefully be able to test it out later.


    I will report back as soon as I can :D

    Edit: Looks like I will have to add some kind of mount from the back of the seat, not too hard for something temporary to trial :)

    Is there any kind of instruction @noorbeast ? I have it installed, I can run the commandline and do stuff but what am I suppose to do ?

    I have not tried it yet but in the StaemVR interface you can access the OpenVR-InputEmulor and there should be an option for motion cancellation, which is where you can set the center of the motion platform.

    Past that you will need to direct questions to the dev, as per the original post.

    It works when I am sat on my chair in the Valve VR starting point but when I launch a game it gets cut off. I must be doing something wrong , I'll keep trying

    Useful feedback @SilentChill, that lets the dev and the rest of us know what to expect and perhaps what may be possible to address.

    It would be helpful to share any controller mount ideas, even if temporary, to encourage others to test it out.

    I've posted on the dev page as well. Need to do more testing when I get chance.

    Just tried pCars running from inside SteamVR and it does not work it stops working in game and when I exit game it starts working again ?? It works perfect in SteamVR dashboard

    Anyone else tried yet ??

    I tried using the Oculus Tray Tool to turn off the Oculus runtime but that did not work.

    Unfortunately it seems like the Rift users are out of luck, as it works directly with SteamVR.

    I have a person over next weekend to try the sim and VR, so after that I will give my Vive a go.

    I guess long term you may need to consider a SteamVR HMD for gen 2, as a 6DOF is the greatest beneficiary of motion cancellation and I suspect Oculus changes will continue to be problematic.

    Another thought @SilentChill, give it a go with Assetto Corsa and choose the new OpenVR option in the graphics settings instead of the Rift.
