Animation

v0.44 から部分的に対応しています。

VRM のアニメーション

VRM は、Animation を使わないという仕様です。

Export は Runtime では動作しません

Runtime では AnimationClip の情報を取得できないため、Export は動作しません。

How to Export an Animator

  1. Add an Animator component to a root GameObject

  2. Create an AnimatorController and set it in the Controller box (Animator->Controller) in the Inspector window

  3. From the UnityEditor’s toolbar, select Windows->Animation->Animation to open the Animation window

  4. Make sure the root GameObject is selected and click the Create button in the center of the Animation window for creating AnimationClip

  5. Add animation keys to this clip

  6. Export as the glb file from UniGLTF->Export

  2. Add animation keys to this clip

  3. Export as the glb file from UniGLTF->Export

Notes

  1. RotationKeyのInterpolation設定をQuaternionかまたはEulerAngles(Quaternion)にすること

Interpolation

  1. For the Animator, all edited clips can be exported. However, the Animator states are not saved

  2. Though a created Animator goes through multiple animations (Animation State Machine), the UniGLTF Importer (UniGLTF-1.25) will only import the first one
