Model Orientation Appears Correct Only in Camera View, Exhibits Tilt in Other Perspectives

[WingkitChou]

I'm working on a project involving 3D human pose estimation and have been utilizing the SMPL model for visualizing the reconstructed human actions. While everything appears fine when viewed from the camera's frontal angle, I've encountered an issue when the model is visualized from the side: the model appears noticeably tilted.

I would appreciate any insights into why this is happening or assistance in resolving this issue. If there are additional details or files that you need, please let me know.

Thank you for your support!

Best, Yuki
