Default (internal) T-Pose in CC3 is not symmetrical -- Left and Right Leg bones have different transforms. This is clear visible (especially for foot) in the CC3 Bone Editor and in the exported FBX files.
It's problematic to create such demo video because this issue is rather complex. So I prepared detailed problem description and included it in the attached ZIP file with additional files (hope these files will be helpful).
If You will have more questions dealt with this problem You can contact me by e-mail.
