| clip | The animation clip to be used. |
| referenceClip | The animation clip containing the reference pose. |
| time | Time that defines the reference pose in referenceClip. |
Set the additive reference pose from referenceClip at time for animation clip clip.
By default any animation clip used in an additive layer use the pose at time 0 to define the 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.
