SimpleFK

What it does

SimpleFK builds one control for one joint, parented under whatever it’s attached to, driving that joint directly. Nothing fancier underneath: no duplicate chains, no blending.

When to use it

Reach for it on a single joint that just needs a plain, posable control: a clavicle, a jaw, an individual finger or spine joint you aren’t chaining. For two or more joints in a row, use FKChain instead (same naming, so a joint can move between the two without a rename). Need space switching or IK/FK matching? That’s AdvancedFK, not this one.

Good to know

• Exactly one joint per instance; selecting zero or more than one won’t build.
• Hand-edited control shapes persist through a rebuild, keyed to the control’s shape option.
• If the parent turns out to be a joint rather than a control, SimpleFK attaches safely instead of nesting into the skeleton.
