Hello.
Thank you for reading this.
'Tracker Role' can be changed at 'MANAGE VIVE TRACKERS' of 'StreamVR Settings'.
If role is 'HELD IN HAND', you can choose 'Hand'.
Then, How can I change it in unity using c# script.
I used 'VIVE input Utility' and searched google many times,
but I can't find the way changing 'Tracker Role' and 'Hand' in unity using c# scripts.
I am waiting for a little help.
Thanks.
