Yes, that’s why I didn’t use this approach before. But it’s easier to calibrate all bones neatly in VR, so - even at the cost of less accurate head calibration after removing headset - probably it worth it. Also, you can ask somebody else to wear on headset/controllers and guide you in a process of calibration.
This mode is already implemented in the executable demo, so you can try it.
Earlier I optimized leg solver for better accuracy with additional knee tracker, but it caused this unwanted behaviour with simple IK solver. Working to decrease this effect. Going to release update at the next week (also, with new function for VR gloves): https://youtu.be/A84-mCBfnyA
Not sure, but right now you can try this: https://sun9-28.userapi.com/c854320/…1SpvQhX6iE.jpg
