Available Formats and Limitations

Format:

  • You can export motion which is recognized as Humanoid Animation, in Unity 2019.4.x.
    • Pure AnimationClip created in Unity 2019.4 is available.
    • Motions in fbx file for Humanoid model will also be available, though there are exceptions.

Limitations:

  • Root pose and lower body motion is not played.
    • This is because VMagicMirror originally assumes upper body only motion.

    • Hand IK will be supported in future updates.
  • Cannot play loop animation.
