IK Constraints in new version?

Someone mentioned in discord that the latest version had IK constraints for hierarchies. How do you do that?

I think they meant FK (which is basically just moving hierarchies), not IK.

Could be wrong though.

The key words there were “an approximation of them”

Yeah, I don’t think there’s any IK constraints (where you move the endpoint of a hierarchy and the rest of the hierarchy chain moves to accommodate).

Current hierarchy is FK.

No IK and no constraints.
