A fix for this has been submitted and will eventually make it’s way into UEFN. It makes the following changes:
- New IK Retarget assets now come with default Ops
- Swapping IK Rigs in a retargeter now throws a pop-up dialog asking if you want to update all the ops to use the new IK Rig.
So for common setups, you no longer have to edit the individual ops.
