subject orientation

[Mahshida hamid]

When I scale the model and uncheck the scaling option, the model appears upright and correctly oriented. However, when I proceed to perform inverse kinematics (IK), the model's orientation changes unexpectedly. Could you help me resolve this issue?

Hello Mahshida,

Have you tried previewing your experimental marker data to see if it is as you expect?

Thanks,

Nicos

yes, I viewed the experimental data, It is oriented 90 degrees.
