retargetting by manually creating Ik rigs and the retargeter is broken in 5.6, automatic work however .
noticed the same thing, any solutions found so far?
Same on my side, try with my characters, the characters from mixamo, and the mannequin imported from 5.5 and also by exporting import mannequins from 5.6.
I also couldn’t get retargeting to work on the same skeleton with different skeletal meshes (the pelvis height was different). What helped was first adding the standard Ops in the new settings, then removing the Root and IK. After that, everything started working properly. I also adjusted the Translation Offset for the pelvis.
