| clip | The animation clip to use. |
| referenceClip | 参照ポーズを含むアニメーションクリップ |
| time | The time that when the reference pose occurs in referenceClip. |
Sets the additive reference pose from referenceClip at time for animation clip clip.
By default, an animation clip used in an additive layer uses the pose at time 0 as its reference pose. This is a big limitation as the reference pose need to be in the played clip.
This function allow you to change this behaviour and use a reference pose from any clip.
