Animation Workbench has grown a lot — from an animation browser into a full workflow suite with a keyframe editor, in-scene pose editing with IK, an event & SFX pipeline, and library organization tools. The old single-page readme couldn't keep up, so everything now lives here, organized and searchable.

Release notes for upcoming versions will be posted in this changelog.

If anything is missing or unclear, let me know on Discord or via the in-editor Feedback Hub (Tools → Animation Workbench → Report a Bug).

v2.1.0​

• Unlocked Live Edit mode for Free users for a limited time
• Keyframe Editor: Added functionality to mute / solo groups which enables layering animations based on the rig (e.g. Humanoid — only animate the lower body for walking animations; this will set the path for additive or override layers in the future)
• Pose-Edit: IK points can now be pinned to their current position (e.g. walking animations — pin the feet IK points to the floor). Being able to pin IK points to transforms, for example a weapon prefab added to the live scene, is planned for future releases
• Added offset functionality to Spawn and Audio events
• UX and massive performance improvements

v2.0.9​

• Added Spawn Events: instantiate any prefab (particle effects, props, world-space UI) from the timeline — at the character root, a specific bone, or a world offset, with lifetime, parenting, rotation and scale controls
• Added optional Feel support to Spawn Events: trigger an MMF_Player on the spawned instance immediately or after a delay, with intensity control. No hard dependency — the section only appears when Feel is installed
• Spawn Events preview directly in the Orbit Preview and in Pose Edit Mode, including particle systems that simulate while scrubbing
• Reworked animation events into one extensible Workbench Event system: all event types share the timeline, undo/redo, duplication, gizmos, tooltips and clip versioning — new event types plug in automatically
• Timeline event markers are now color- and icon-coded per event type, and the create menu lists every available event type
• Scene view event gizmos now show the exact problem (e.g. a missing SFX key or prefab) instead of a generic "Missing" label
• Added a searchable, hierarchical bone picker to the Audio and Spawn Event inspectors — the field shows the bone name, the full path lives in the tooltip
• Audio and Spawn Event inspectors now detect incomplete scene setup: missing SFX Manager, missing Runtime Audio Database, missing SFX Source Prefab, and characters that play the clip without an Event Receiver — each with a one-click fix
• Entering Play Mode now logs clear warnings when characters play event clips without a receiver or when the SFX Manager is missing, instead of failing silently
• The SFX Manager now warns when an audio event references a key that is missing from the Runtime Audio Database
• The audio Preview button now also works in Play Mode
• Clip version snapshots now preserve every event type and restore them reliably, including after editor restarts
• Generated audio assets (Runtime Audio Database, SFX Source prefab, Audio Mixer, Channels) are now organized under Assets/Settings/AnimationWorkbench — re-baking updates the existing database in place, so references never break
• Redesigned the Animator Controller inspector: structure overview, prefab usages, referenced clips with durations, and a new "In Open Scenes" section listing scene objects that use the controller
• Faster Audio Event inspector (removed a duplicate full-project scan when opening)

v2.0.8​

• Added Rescan Animation Library to fully rebuild the animation library from the current project
• Added Rescan Characters to refresh project characters and automatically reassign preview characters
• Preview characters are now automatically assigned via an Animation Clip's Animator Controller when bone matching fails (primarily for Generic clips)
• The Characters context menu now lists all characters using the clip's Animator Controller
• Middle-clicking a character in the Preview Character popup now pings its prefab while keeping the popup open
• The Show Particles toggle is now only shown when the preview character contains particle systems
• Eliminated Orbit Preview stuttering during thumbnail generation
• Fixed incorrectly framed thumbnails for Generic characters with import scaling
• Fixed missing Animation Controllers and Characters context menu entries after rebuilding the library
• Newly imported clips now use the same character matching logic as the initial library scan
• Smoother, larger Orbit Grid with distance fade
• Reduced thumbnail generation overhead by encoding PNGs only once for both memory and disk cache

v2.0.7​

• Performance: major speed-ups in Scene-Pose Mode (bone drawing, mesh influence overlay), during keyframe editing (onion skin, working-clip updates) and in the Animation Browser while loading
• Scene-Pose: bones now grow and highlight as the cursor approaches, hovered bones get a selection ring, and clicking bones is far more forgiving
• Animation Browser: list-view badges are now written out (Humanoid / Loop / Audio) when there is enough space

v2.0.6​

• Fixed squashed / too-short track rows in the Keyframe Editor on some Unity versions & UI scales
• Fixed mouse-wheel zoom (Ctrl / Shift / Ctrl+Shift) not working on Windows or when hovering the track list
• Performance: major speed-ups during playback, track-value editing and Scene-Pose Mode
• Keyframe Editor: removed the track-list group color bar (kept only the curve color in Curve view) and moved the playhead key indicator to the left of the track name
• Animation Browser: grid cards now show clip length + Humanoid/Loop/Audio badges and cleaner names (FBX prefix stripped, full name on hover)
• Editor fonts now match Unity's Project Browser
• Several UX and design polish

v2.0.5​

• New: Collapsible track groups in the Keyframe Editor — tracks are now organized under group headers (muscle groups for humanoid, bone groups for generic rigs); collapsed groups show all child keys as an aggregated summary row
• New: Group interactions — click a header to collapse/expand (Alt-click for all groups), right-click a group row in the dopesheet to add keyframes to that group only; collapse state persists across sessions
• New: Track show filters in the visibility menu — "Only Animated" and "Only Keyed at Playhead" (updates live while scrubbing), plus a "Show Groups" toggle to disable grouping entirely
• New: Events header row above the track list — mute/unmute audio events and collapse/expand all groups from one place
• Keyframe Editor: Fixed vertical misalignment between track list rows and dopesheet rows
• Keyframe Editor: Fixed the scrollbar gutter showing a different background when no scrollbar is needed
• Scene-Pose: Fixed humanoid pose drift and snapping on consecutive bone manipulations
• Scene-Pose: Rotating the hips or an unmapped root bone (e.g. Rigify exports) is now correctly written as root motion (RootT/RootQ)
• Added play/pause button to the Single Clip control bar

v2.0.4​

• Reworked Scene-Pose Mode and Scene-Pose Overlay
• Several UX improvements and bug fixes

v2.0.3​

• New: Runtime Audio Channels — group SFX for muting, volume, mixer routing and voice limiting via ScriptableObject channel assets
• New: Audio Control Center on the SFX Manager — live per-channel mute & volume, global mute, active-voice counts and a "?" panel explaining the runtime code API
• New: Per-character control on the Audio Event Receiver — muted flag and Channel Override (route a player and an NPC sharing the same clip to different channels)
• New: Manual key-triggered playback — Play(key) from code or the receiver, running through the same gate pipeline as animation events
• New: Gate pipeline — playback now passes through extensible gates (Mute, Probability, Cooldown); add your own via AWSFXManager.AddGate(...)
• New: Per-SFX Play Probability, Cooldown and Priority, plus per-channel Voice Limit with steal policies (Suppress / Steal Oldest / Steal Quietest)
• Audio Library: added a "Routing & Behavior" section with detailed hover tooltips on every playback field
• Fixed voices being recycled too early (pitch and start-offset are now accounted for in playback length)
• Fixed the SFX pool growing unbounded under heavy load
• Several UX improvements and bug fixes

v2.0.2​

• Added a shader for onion skin ghosts to also blend in the mesh
• Many keyframe editor design improvements
• Centralized Hotkey Manager
• Multi Compare: massive overhaul of the UI, and Clip Sync was added

v2.0.1​

• New: Customizable keyboard shortcuts — rebind editor hotkeys in Settings ▸ Hotkeys, with conflict detection
• New: Hotkey cheat-sheet on the "?" button (hover to view, click to edit)
• New: Arrow-key timeline navigation — step by interval, Ctrl to jump keyframe-to-keyframe, Shift to extend selection
• New: ↑/↓ to select the track above/below
• Ctrl+A and Ctrl+D now also select-all / duplicate keyframes (context-aware: keyframes or events)
• Several UX improvements and bug fixes
