After a good 30 minutes trying to figure out why my animbp wasn’t working, I finally realized that my HMD was no longer accurately updating its height (Z) position. Originally, as I would physically crouch and stand, the relative position would have a range of ~70 to ~155. Since the update, the height is stuck at 135. Even stranger is that the only way I can get the tracking to update the height is to rotate (pitch) the HMD. Anyone experience a similar issue?
So, turns out it had nothing to do with the update, and everything to do with my kids. They had stuck their fingers over the front-facing cameras and left a residue of god knows what. Cleaned the cameras and we’re back to the races. Huzzah!
