Hi, thank you for the great work! And I want to know why my bvh converted from smpl is upside down? Do you have any solutions？

Hi, thank you for your feedback!
Perhaps the difference in coordinate systems may have an effect. (SMPL sets the y-axis upward and the z-axis forward.)
The motion itself does not seem to be broken, so it is possible that only the rotation of ROOT is odd.
A simple solution is to multiply a 180 degree rotation around the z-axis to the ROOT rotation.
Yes, I multipled a180 degree rotation around the z-axis and y-axis to solve the problem temporarily.
