Managing Full Body Animation

The full-body animation (iMotionPlus) is a combination of both facial (iTalk) and body (rlMotion) animations. After importing full-body animation assets in the .iMotionPlus tab, you can configure both facial and body animation settings to shape the motion.

  1. ClosedFile Info
    • File Name: Displays the original filename of the imported animation.
    • Animation Duration: Displays the total animation length in seconds.
  2. ClosedBlending
    Controls how the animation blends in from the previous action and blends out when it ends. These values need to be calibrated based on animation length and desired visual smoothness. You can set a numeric value (in seconds) with up to two decimal places for blending.
    • Blend In Time: Defines the time taken to transition from the previous animation to the first frame of the new animation.
    • Blend Out Time: Defines the time taken to transition from the last frame of the animation back to the original state.
  3. ClosedFacial Animation Settings
    1. ClosedEnable Facial Animation
      Decides how the iMotionPlus animation will be played. It is checked by default to include facial animation (iTalk).
    2. ClosedAnimation Speed
      Controls the playback speed of the animation in a float value with up to two decimal places. The value is 1 by default for normal speed. If the value is set to 2.0, the animation plays at 2× speed. If the value is set to 0.5, the animation slows down to 0.5× speed.
    3. ClosedPartial Mask
      Partial masking allows certain animation tracks to be hidden during playback, depending on the context. These options are enabled by default to enable facial expressions for all facial parts.
      • Non-speaking State
      • Speaking State
        • Head: Follows the driven Head animation (Speech Profile) from the Speech Graph.
        • EyeLook: Follows the driven Saccade animation (Speech Profile) from the Speech Graph.
        • EyeLid: Follows the driven Brow animation (Speech Profile) from the Speech Graph.
        • Brow: Follows the driven Brow animation (Speech Profile) from the Speech Graph.
        • Mouth: All mouth animations are automatically enabled and replaced by NVidia ACE A2F Lip Sync, which translates speech into ARKit facial animations.
        • Others: Enables the morphs other than the above facial parts in the facial animation (Cheek for example).
        If no animation is driven while speaking, the procedural animation from the Idle Expression Graph will take over.
      • Intensity: Controls the intensity percentage of each facial part with a float value of up to two decimal place precision.
      Disable partial facial expressions by unchecking the corresponding facial parts.
  4. ClosedBody Animation Settings
    1. ClosedEnable Body Animation
      Decides how the iMotionPlus animation will be played. It is enabled by default to include body animation (rlMotion).
    2. ClosedAnimation Speed
      Controls the playback speed of the animation with a float value up to two decimal place precision. The value is 1 by default for normal speed. If the value is set to 2.0, the animation plays at 2x speed. If the value is set to 0.5, the animation slows down by half.
    3. ClosedAnimation Mask
      There are two types of masking behaviors for body animation.
      • Keep Head Clip Motion
        • Enabled: Uses the animation's own head movements.
        • Disable: Applies the head behavior from the last executed Auto Profile.
      • Disable Look-At During Performing
        • Enabled: The eyes follow the animation's own behavior during playback. If the animation lacks eye movement data, it will apply the last executed Auto Profile settings.
        • Disabled: The eyes remain locked onto the last targeted camera during playback.
