HIK hasn't been updated since 2013. A major issue missing is having the capability for the Custom Rig to have the same functionality as the Control Rig has -- Fk+Ik limbs. The xml should have ability to map the forearm/legs to Fk rotation, elbow/knees to Ik pole vector translation, and wrist/foot to Ik-Fk translation and rotation similar to the Controls. I've tried this as a test and the markers are missing ID's to tie to. I don't know why the UI configuration is missing ID's or hasn't been updated?
Other than deleting the custom rig and remapping the controls to one or the other Ik or Fk (not both combined), there is no easy way to do this. The ID's order should be exposed. Unreal5s retarget has been modified, there needs to be an update to the HIK tool.
Thanks!
