Hi @chengnay,
I posted some screenshots of my manager vive trackers in steam VR Settings, please se my first post on page3..
Concerning the json changes, i reverted them, so the tracker i as tracker again and not a controller 😉
VIU Plugin version : yes i did a mistake, it was 1.11.0 and not 1.0.11
Here is a link to download the Unity Project :https://we.tl/t-6O96Vz2mjs
I started from a blank unity project, imported VIU, then, Steam VR.
The scene you should open is named "MultiTrackers" and is under the "Assets/_MultiTrackers/Scenes/" folder
I took the VUI example scene "Assets\HTC.UnityPlugin\ViveInputUtility\Examples\7.RoleBindingExample\RoleBindingExample.unity" as a start and added some cubes and the "TrackerFollow.cs" script i made to track the different trackers.
I associated the trackers roles with the VIU roles panel (VIUBindingInterface) then tested the pogo pin input on the trackers :
When using only two trackers (without controllers), connecting pin 2 and 6 (menu button) with a wire works nicely on both of them (The cubes scale up )
When i add more trackers or the controllers, the pogopin input will not work consistently anymore.
If you need more info i can make a video to show exactly the problem and how it is reproduced step by step
