I own a vive too and had the same problem but i was able to do a bit of a workaround-
- open up defaultsettings.ini in BricksperienceVR\Config
- at the bottom in the action mappings section look for MenuInteractionRight/Left, replace the last bit, "FaceButton1" with "Thumbstick" on both of them
- then in the action mappings go to LeftGrip and change that to FaceButton1 (or leave it blank, not sure if that works though)
- finally go to the ResetTracking mappings, change Left_Thumbstick to Left_Grip1 and Right_Thumbstick to Right_FaceButton1 (or leave the right one blank too)
This lets you click the pads to hold the Legos and your left grip will reset the tracking.
