Joint pose

[sebastianopazo1]

Hi! I'm facing some problems when trying to replicate the pose of the joints in Unity. First of all I extract the pose from the script demo_smplx.py, specifically in the output .pkl file as a rotmat. Then I process this data to save it in a .txt file to send it to Unity. The problem is that when I apply this to the SMPL-X in Unity the pose for each joint don't make the same moves as in the rendered video. Specifically the rotation arround z-axis has some radical changes in the position. Just as shown in this image.

Am I applying the wrong pose to the pelvis?
Thanks for your help!
