Fix "(Missing!)" animation curves in a few clicks, and copy animation keys from one object to many. Renaming, moving or reorganising a hierarchy no longer breaks your animation clips.Rename a bone, move a sprite under a new parent, or rebuild a character rig, and Unity's Animation window marks every affected curve as (Missing!). Normally your only options are editing paths by hand or animating it all again. Animation Curve Rebinding repairs these curves inside the Animation window, without leaving it.Rebind missing curves. Select the (Missing!) rows, then click the object they belong to in the Hierarchy. The panel shows how many curves will move, warns you if the target already has some of them, and gives you three options:Move: move the curves to the new object.Duplicate: give the new object a copy and keep the originals.Exchange: swap the curves between the two objects.Copy and paste animation keys. Copy all keys of an object and its children, select one or more objects in the Hierarchy, and paste. Children are matched by name, and pasting works across clips. Before you paste, the panel shows how many curves will be written, how many will replace existing ones, and how many will be skipped. One idle animation can be shared by a whole row of props in seconds.Rebinder window. Window > Animation Curve Rebinder has a three-column view: animated property → target object → action. You can move, duplicate or exchange any property, including ones that aren't missing. Use it to rearrange animations on purpose.It works with any genre or art style: 2D sprites, 3D rigs, UI, props, cutscenes. Anything animated with Animator and AnimationClips is supported. Every change can be undone, and an example scene is included.Key featuresPanel built into Unity's Animation window that appears only when it applies to your selectionRebind (Missing!) curves to any object under the same Animator: Move, Duplicate or ExchangePick targets by clicking in the Hierarchy or dragging into a Target fieldWarns before overwriting curves that already exist on the targetCopies keys of an object and all its children, then pastes them onto many objects at onceChildren matched by name when pasting; curves with no matching child or component are skipped and reportedPastes between different clipsCopied keys survive script recompiles and entering Play modeKeyboard shortcuts: Copy Keys (Ctrl/Cmd+Alt+C) and Paste Keys (Ctrl/Cmd+Alt+V), changeable in Edit > ShortcutsStandalone Rebinder window (Window > Animation Curve Rebinder) for rebinding any propertySupports float curves and object reference curves (e.g. sprite swaps)Every action can be undoneBuilt-in help for each panel section; disabled buttons explain why they're disabledLight and dark Editor themes supportedNo runtime code or performance cost (editor tool only)CompatibilityTested with Unity 6000.6Works with any render pipeline (Built-in, URP, HDRP)The Animation window panel reads Unity internals.
