Curve Focus – Find & Fix Broken F-Curves (Graph Editor)
Only Selected Bones does nothing
Switch to Pose Mode, select bones, then use Sync to Selected Bones or enable the checkbox and Isolate.
Fix Euler does nothing
Your curves are probably quaternion (rotation_quaternion). Euler unwrap only applies to rotation_euler. Use Smooth Visible Curves or Fix Safe Problems.
Scan score is low on Mixamo / mocap
Dense mocap often has many minor/warning flags (redundant keys, jitter). That’s expected. Use Fix Safe Problems, then scan again — the score should rise.
Fix Euler does nothing
Active object has no action to filter/scan
Select the object that actually has animation (usually the Armature). Object mode is fine; the Action must exist on that object.
