AdvancedFK

What it does

AdvancedFK builds one control for one joint, much like SimpleFK, but instead of parenting under an ancestor control it sits in world space and carries a switchable space attribute. Pick a target in Properties (its skeleton parent, world, or any joint you add) and the control follows that space.

When to use it

Use it for anything that changes parent mid-shot: a prop that starts in a hand and ends on a table, a weapon, an accessory that hops between joints. If the control only ever needs one parent, use SimpleFK instead, it’s the plainer, cheaper choice.

Good to know

• The marking menu adds a Match to Space and a Switch to space entry per target you’ve added, on top of the usual Zero All / Zero Translates set.
• One joint per instance; selecting zero or several fails before the component can be added.
• The control’s name comes from the joint’s short name, so two joints sharing a short name collide on control naming.
