timeTime that defines the reference pose in referenceClip.

Description

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.
