What's new for Motion LIVE 1.1 and LiveFace Profile 1.05 

Reallusion's latest facial mo-cap tools go further, addressing core issues in the facial mo-cap pipeline letting you produce better animation. From all new ARKit expressions to easily adjustable raw mo-cap data as well as re-targeting, to multi-track facial recording and essential mo-cap cleanup - we're covering all the bases to provide the most powerful, flexible and user-friendly facial mo-cap approach yet. Read below and find out what we have achieved in this update. The biggest issue with all live mo-cap is that it's noisy, twitchy and difficult to work with, so smoothing the live data in real-time is a major necessity; Because if the mo-cap data isn't right, or the the model's expressions aren't what you want, and the current mo-cap recording isn't quite accurate then you need to have access to the back-end tools to adjust all of this. Finally, while you can smooth the data in real-time from the start, you can also cleanup existing recorded clips using proven smoothing methods which can be applied at the push of a button.

Learn more information from the iPhone Face Mocap page.


  • 1. iPhone LiveFace App Update (High Tracking Precision)
    LIVE FACE data streaming has increased in accuracy from two decimal points to five. 
    >>> (*Requires to update LIVE FACE iPhone App to version 1.0.8 (Feb 22, 2021)   / (see video)
    https://forum.reallusion.com/uploads/images/3273d320-4a08-4f19-aa11-1310.png

  • ARKit 1:1 Blendshapes (52+11)
    iPhone LiveFace supports ExpressionPlus (ARKit 1:1 mode). The iPhone tracking data is now one-to-one mapped to 52 scan-based blend-shapes from CC3+ character base, giving much more expressive facial performance. / (see video)
    Additional tongue movement is also included. (Visit "Facial Expression page")
    https://forum.reallusion.com/uploads/images/98779a68-15a1-4c1d-94fe-04e0.png

  • 2. Tracking Data Inspector: Multiplier added
    • No longer just a data inspector, with "Multiplier", you can boost or weaken the tracking data strength.
    • Use this feature to compensate the imbalance of tracking data strength, and help accommodate the performer's effective range.
    • Added Color Coding for brows, eyes, jaw, cheek, and tongue. It helps to easily identify triggered facial region.
      (see video)
    • https://forum.reallusion.com/uploads/images/963e6aba-9122-4a92-88f1-258f.jpg

  • 3.  Multi-pass Recording: Capture Mode - New, Add, Replace
    • New: Start a new recording, overwriting the original clip.
    • Replace: A very powerful feature! Now you can use Replace to erase selected muscle area, or replace the selected muscle area with new puppet performance.
    • Add: Blend the new puppet performance onto the underlying clip.
      (see video)
      https://forum.reallusion.com/uploads/images/a8254430-9b9a-4d66-b6aa-01e1.jpg

  • 4. Real -time Smooth Tab
    • Added a new Smooth tab, with separate Smooth Sliders for Head Rotation, Muscle, Eyes, Eyelid.
    • Usually we need to give some smooth values to Head Rotation for natural head turn.
      (see video)
      https://forum.reallusion.com/uploads/images/8087671a-4dd5-4ff9-94bd-9690.png

  • 5. New Expression Mapping
    • Re-targeting (tracking data to blend-shape) is made easy with the new, flexible mapping UI.
    • Default and ARKit 1to1 presets provide instant re-targeting for CC3+ avatars.
    • Customize expressions easily by blending them.
      (see video)
      https://forum.reallusion.com/uploads/images/7e86938f-aaf7-4767-9ee5-6e4c.jpg

  • 6. Post Smooth (Timeline - Expression Track - Clip)
    • This feature can effectively fix mo-cap judders, snappy head rotation, or any eyelid, eyeball, or muscle twitches
    • Smooth recorded data on clips using either Smoothing (moving average) or Down-sampling (key reduction) methods.
      (see video)https://forum.reallusion.com/uploads/images/39d55bbf-ad5b-42ff-97b8-89e0.jpg
Known Issues:
  • If the CC3+ character was denied the update to ExpressionPlus, the mocap result will not be shown, and one will need to switch back to Default in the Mapping panel. 
    https://forum.reallusion.com/uploads/images/4ccb268d-75a2-402f-9c38-cc29.jpg
  • Using two different Full Body Profiles (Neuron or Rokoko) on the same character like applying A profile to the body and B profile to the hands, will cause the application to crash.
