I'm having a lot of trouble getting grabbing to work in the demos. I have a few issues: 1. I can only seem to have one "active" controller. Meaning, when I press buttons on my right controller, it pops to my side and works as normal, but the left one disappears back to where it was "anchored" in the scene. I can never have them both at my side functioning. 2. The finger movements and grabbing doesn't work. I have only gotten grabbing to work if I use a DistanceGrabber and change the Grabber script to be L/R Touch Tracker (the hand script is just L/R Touch). Even then, the hand doesn't make any animations when grabbing.
I've followed a bunch of tutorials, even a very recent one here (https://www.youtube.com/watch?v=weL4aRe1FRk). They all seem to have hands working pretty well out of the box, at least the intricate finger tracking. I'm using 2019.1.10f1 with all recommended build settings.
