UE4 Support?

[PJninja]

Hi all,

I am trying to handle multiple Input events from 4+ Vive Trackers in our UE4 Sim but am unable to do more than 2 and the 2 I get don't come with a signature just passing a generic trigger event.

I saw that VIU does handle what I need but it is only for Unity. Any possibility of porting to UE4 or is there a UE4 solution related to VIU?

This is for a large project and am open to any help,

Thanks

@PJninja I don't quite get what do you mean by "don't come with a signature just passing a generic trigger event".

By the way, what role did you set for your trackers in SteamVR's "Manage VIVE Trackers"?

@PJninja I did manage to get input event from Tracker role that are not set as Held in Hand.

You need to modify your tracker json file to corresponding role.

For example,

{
    "name": "Default bindings for Vive Trackers",
    "controller_type": "vive_tracker_left_knee",
    "last_edited_by": "UnrealEngine",
    "bindings":
    {
        "/actions/main":
        {
            "sources": [

                {

                    "mode": "trigger",
                    "path": "/user/knee/left/input/trigger",
                    "inputs":
                    {
                        "click":
                        {
                            "output": "/actions/main/in/GrabLeft"
                        }
                    }
                }

            ],

            "poses": [
                {
                    "output": "/actions/main/in/special4",
                    "path": "/user/knee/left/pose/raw",
                    "requirement": "optional"
                }

           ]

        }
    },
}

 

Please note that you cannot set more than 1 tracker to same Tracker role.

Even if the tracker is disconnected, you need to set the Tracker role to DISABLED.
