Unity Vive XR Elite - Body Tracking: ERROR_BODYTRACKINGMODE_NOT_ALIGNED

[SimonT]

Hi all,

I am trying to get Body Tracking running on a Vive XR Elite with 3x Ultimate Trackers as described in this documentation https://hub.vive.com/storage/docs/en-us/UnityXR/UnityXRBodyTracking.html, however when trying to activate the tracking within Unity I'm getting the error messages below. This was using the two controllers, and three Ultimate Trackers assigned to the Waist, Left Ankle, and Right Ankle roles.

 

Bodytracking RESULT: ERROR_BODYTRACKINGMODE_NOT_ALIGNED
CreateBodyTracking() The body tracking mode UPPERBODYIK and calibration role Arm_Handheld are NOT matched.

 

Using the Demo scene shown here https://www.youtube.com/watch?v=s2Rl1Uxegxo, the "Arm" tracking mode works fine, but all of the other tracking modes produce the errors above. If anyone has any information that would help, I would greatly appreciate it!

 

Thank you!

Hi @SimonT,

May I know which WaveXR Plugin version did you install?

And, which Unity version?

[SimonT]

Hi @VIVE_chengnay,

Thanks for your quick reply, I'm using the following versions;

Unity: 2022.3.10f1
Wave: 5.5.0-r.10

Hi @SimonT,

Could you try latest version(6.1.0-r.8)?

[SimonT]

Hi @VIVE_chengnay,

I have created a new project using the latest SDK version; however in the demo scene, none of the tracking modes are working now. Below are some debug/error messages;

1. This error occurs on start-up, before any calibration or tracking is attempted.

 

2. These logs are when attempting to calibrate/track

Hi @VIVE_chengnay,

Sorry for pestering you again with this, but do you have any more information? (and also approve my previous post please)

Thanks!

Hi @SimonT,

Since the Body tracking feature is still in beta stage, and here we'd share additional doc to see this could be helpful for you to understand the whole calibration flow and the rest of set up for different trackers configuration. [Unity] BodyTrackingTutorial.pdf.

If you still encounter the failed issue, could you share us the log for further analysisi?

Thanks.
