Pose a rigged model, measure what its bones actually drive, and search for a pose.
Model
time0.00s
Or drop a .glb anywhere on the viewport.
Bones
Pose
Pick a bone above. Sliders sit on top of the clip, so you can
scrub and pose at once.
Measure
select a bone
Reach is measured on the skinned vertices the bone actually drives, not
on the bone's own origin — a bone can own geometry that sits nowhere near its pivot.
Search a pose
Tick bones in the list to include, then maximise reach
in the direction above. Six angles searched per bone.
