From a previous I posted this:
"Hey Eric, I was able to get your Playmaker Actions loaded without any issues. I am a bit lost with how to get the position and rotation of the controllers. So I'm using 'Get XR Device Transform Info' action, every frame, but I'm not getting the coordinates. I added three 'XR Controller Input.cs' scripts to an empty game object, and and choose Left Hand, Right Hand, and Head for those. Is there something else I need to do?"
I think we also talked on Discord (it was a while back), I did ask some questions and you never replied to them there.
