Good morning, 

I am using one of the free motions to try the workflow in Blender using Autorig Pro. I am following the tutorial you have in youtube step by step ( including reseteing the rotation of the bones of the limbs and using the mapping preset). Everything seems to work fine but when I play the animation the knee of the character is twisting the other way around in some frames.

This is happening to me with the Walk Relax animation.

Any idea what could be the error? I am happy to share the Blender scene if that helps.

Thank you.

Hi manuelgperez,

Correct me if I'm wrong, we believe the problem is caused by the Auto-Rig Pro's retargeting algorithm,
please follow this additional tutorial on "Interactive Tweaks for Adjustments after Retargeting"

thank you.
