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.
I second this, even in the 5.6.1 release retargeting with the Op Stack is a hot mess. I’m always happy about new features, but I absolutely hate it when previously WORKING features are replaced with undocumented beta stuff (like that Op Stack). We can no longer make simple global adjustments, retargeting isn’t even working half the time, but apparently “it’s all better this way”. Yeah erm… not for me.
Knowing EPIC this probably works somehow, they just didn’t feel it necessary to tell us HOW.
