Unity 2019+ render/input detection problems whenever I use a Third-Person camera for Mixed Reality

[valentinlangegger]

Ever since I tried to create a Mixed Reality project in Unity last year, I have encountered a redner/input detection problem, which I'm extremely confused of.

Gear:

• HTC Vive
• 2x HTC Vive Controller
• HTC Vive Tracker

Sofware: -SteamVR -Unity 2019+ (are the versions where I get these bugs)

I created my first Mixed Reality Project in Unity2017, where everything worked, but now that I wanted to try Unity2020, I got a bug which I can not solve.

2017

This is the view with my headset only. Everything works perfect

These are the views when i connect my HTC Vive Tracker. 1 is the headset, 2-4 are the different layers of the tracker. Again everything works perfect

2019

This is the view with my Headset only. Everything works perfect as it should

These are the four views which I get when i connect my Tracker, but 2-4 are controlled by the headset AND the tracker, and the first view is not controlled by anything

2020

First person with headset only works fine again

These are the four views which I get when I connect the Tracker. First one is not controlled by anything and 2-4 are both controlled by my headset and the tracker again. But now in the 2020 version there is also a render bug in the first view

These problems only encounter whenever I try Mixed Reality in Unity 2019+. Normal First Person VR works fine.

Possible reasons: -SteamVR not supporting Unity 2019.3+ (?) -Hardware too old (?)

Thanks in advance
