I’ve tried with Kinect 360, Dell as well. I managed to get it somewhat working once with VRChat, but not for long, and it was very finicky. I couldn’t get it calibrated correctly and it only worked once, every other time I was sinking in the ground no matter what I tried. Also, it seems that driver4vr makes me lose tracking of the controllers very often as well.
I tried both full body and upper body, I couldn’t get consistent and/or satisfying results so far.
