A single joint that rotates to face a separate, draggable aim control, built for eyes and anything else that needs to look at a target.
What it does
Drag the target, the joint turns to face it
FKAim gives one joint a control plus a second "aim" control placed out in front of it.
The joint's rotation follows an aim constraint pointed at that second control, so dragging the aim control turns the joint toward it instead of rotating it directly.
When to use it
The eye-rig block, and any look-at target
Eyes that converge
Built as the eye-rig block: two FKAim instances sharing a link_group get a shared look-at control, so both eyes converge on one point.
Or solo look-at
Works alone for anything that should face a draggable target rather than being rotated by hand:
Tune the aim setup
aim_distance and aim_axis set how far in front of the joint the aim control sits and which axis points at the target.
link_group is opt-in
Leave link_group empty for a single, independent aim target; only set it when two or more instances should share one control.
Target joint must exist
The target joint has to already exist in the scene when you build.
