What you'll learn: Installing the QuickMagic Maya redirection plugin, mapping AI mocap to your character's face Rig, cleaning jitter and foot-sliding in the Graph Editor, baking
keyframes, and exporting animation as FBX for game engines or rendering.
Part 1: Facial Animation Redirection in Maya
Facial animation redirection is the process of taking AI-generated motion capture data from QuickMagic and applying it to your custom Maya character Rig. Unlike simple joint retargeting, facial redirection requires careful mapping of blend shapes, bone rotations, and expression data from the source capture to your target character.
1.1 Prerequisites — What You Need Before Starting
- QuickMagic account — Sign up for free to generate AI mocap data from video
- Autodesk Maya 2022+ — recommended for best FBX import handling and Rig evaluation performance
- Redirection plugin — download from the official plugin page (joaen Gumroad)
- A character Rig in Maya — with properly named joints and facial blend shapes configured
- QuickMagic mocap data — generated from your reference video through the QuickMagic platform
1.2 Step-by-Step Redirection Workflow
1 Generate mocap data in QuickMagic
Upload your reference video to the QuickMagic AI platform. Select full-body + facial capture mode for complete performance data. QuickMagic's AI analyzes the video frame by frame, extracting bone rotations, blend shape weights, and expression data. Once processing is complete, download the data package containing the FBX file and facial animation data.
2 Install the Maya redirection plugin
Download the QuickMagic redirection plugin and place it in Maya's plug-ins directory. Open Maya, navigate to Window > Settings/Preferences > Plug-in Manager, and enable the plugin by checking both Loaded and Auto load. A new shelf or menu item should appear for QuickMagic tools.
3 Import mocap data into Maya
Use File > Import to bring the QuickMagic FBX file into your Maya scene. The FBX contains the skeleton hierarchy with animation keyframes baked onto every joint. Verify the imported animation plays correctly by scrubbing the timeline — you should see the full-body and facial mocap data in action.
4 Map facial animation to your character Rig
Open your character Rig in the same Maya scene. Use the QuickMagic plugin's Redirection panel to map the source mocap skeleton to your target character. The plugin handles facial blend shape mapping, transferring eye blinks, mouth shapes, eyebrow movement, and jaw rotation from the AI capture onto your character. Adjust blend shape intensity sliders as needed for your character's proportions.
5 Verify and tweak the redirection
Play back the animation on your target character. Look for common redirection artifacts: exaggerated expressions (blend shapes too intense), jaw popping (rotation limits exceeded), and eye misalignment (gaze targets not matching). Use Maya's Animation Layers to add corrective animation on top of the redirected data without modifying the source keyframes.

Part 2: QuickMagic Data Cleaning in Maya
Raw AI motion capture data — even from QuickMagic's advanced algorithms — often contains minor imperfections that need cleaning before the animation is production-ready. Common issues include joint jitter (small, rapid oscillations), foot-sliding (feet not locking to the ground plane), and curve noise (unwanted high-frequency variations in the animation curves).
QuickMagic includes built-in data cleaning tools that integrate directly into Maya's animation workflow, saving you hours of manual cleanup.
2.1 Common Mocap Artifacts and How to Fix Them
- Joint Jitter — Rapid, small oscillations in joint rotations (especially fingers and facial joints). Fix: Select the affected curves in the Graph Editor and apply Curves > Smooth with a moderate filter setting (2-3 iterations).
- Foot-Sliding — Feet that glide across the ground instead of staying planted. Fix: Use QuickMagic's Foot Lock tool to constrain foot IK controllers to the ground plane during contact frames. Manually adjust IK handle keys in the Graph Editor for precise control.
- Bone Length Inconsistency — Joints stretching or compressing unnaturally. Fix: Enable IK/FK matching in the QuickMagic cleanup panel. This re-constrains bone lengths to match the character Rig's default proportions.
- Expression Clipping — Facial blend shapes exceeding their valid range (0.0-1.0). Fix: Use Graph Editor > Curves > Simplify Curve and clamp values with Maya's Set Driven Key limits.
2.2 The QuickMagic Cleaning Workflow
1 Analyze animation curves for noise
Open the Graph Editor (Window > Animation Editors > Graph Editor). Select all animation curves and visually scan for high-frequency noise — these appear as jagged, rapidly oscillating lines. The QuickMagic plugin's Curve Analysis tool can automatically highlight noisy curves in red for quick identification.
2 Apply smoothing filters
In the QuickMagic cleanup panel, select the Body Smoothing or Facial Smoothing preset depending on what you're cleaning. Body filtering uses stronger smoothing (fewer keyframes) to eliminate large jitter, while facial filtering uses finer settings to preserve subtle expression detail. Apply and preview — you can undo and adjust the filter strength.
3 Lock foot and ground contacts
Select the character's foot IK controllers and run QuickMagic's Foot Lock Detection tool. It automatically detects frames where the feet should be planted on the ground and constrains them. Manually review the detected contact frames and adjust any false positives or missed contacts in the timeline.
4 Refine in the Graph Editor
After automated cleanup, manual refinement in Maya's Graph Editor gives you the final polish. Use Weighted Tangents for smoother easing, Break Tangents for sharp transitions (like foot impacts), and Euler Filter for curves that flip rotation values unexpectedly. This step is where your animation goes from "good" to "production-ready."
5 Bake and finalize
Once you're satisfied with the cleaned animation, select all animated controllers and choose Edit > Keys > Bake Simulation. Set the sample rate to match your target frame rate (24fps for film, 30/60fps for games). Baking locks in all your cleanup work into clean, evenly-spaced keyframes.

Troubleshooting: Common Issues in QuickMagic-to-Maya Workflow
Pro Tips for Production-Quality Results
- Use high-quality source video: QuickMagic's AI performs best with well-lit, front-facing video at 30fps or higher. Avoid heavy motion blur, occlusions, and extreme camera angles.
- Name your joints consistently: Match your Maya character's joint naming convention to the QuickMagic skeleton. Consistent naming (e.g.,
Spine_01,L_Arm_Upper) makes redirection near-automatic. - Layer your cleanup: Always work on a duplicate animation layer. This preserves the original mocap data as a fallback and lets you A/B test your cleanup results.
- Clean body first, then face: Full-body smoothing can accidentally over-filter subtle facial expressions. Clean body animation first with stronger filters, then clean facial data with lighter settings.
- Test in your target engine: Export a short clip of cleaned animation to Unreal Engine or Unity early in the process. What looks good in Maya's viewport may behave differently with a game engine's animation system.
