Human IK is a great tool that can get you through rigging quickly, but it has it’s own considerations…
- Do not ad extra neck bones to the rig, HumanIK doesn’t ad controls properly if you do.
- Parent props to bones and not controls. Controls will often drift from your joints and then so will the props.
- Do not scale bones to fit your rig unless it is inside the skeleton generator. Scaling bones outside the generator causes issues.
