When you copy a track and paste it onto another,
itstype(Eulerorquaternion)ispastedaswell.
This sometimes results in animations switching
from quaternion to Euler and vice-versa.
Euler t angents of copied poses or postures are
never copied. If you copy an Euler track and paste
it onto any type of track with A uto Key turned on,
the current TCB or tangent values (depending
on the type of track onto which you pasting) are
ignoredandinsteadsettoDefault.
Following the same rule, pasting a pose or posture
on a Euler track with Auto Key turned on doesn’t
transfer the TCB va lues of the copied t rack. If a
new key is created before pasting the track, the
resulting tangent is set to Default.

When you load an external biped asset file (BIP)
onto a biped, they each might contain different
animation controllers (for example, a Euler asset
loaded onto a quaternion biped). When this
happens, the biped animations are converted to
match the cont roller from the biped asset file.
When you save a biped asset file, it stores b oth
Euler tangents and quaternion TCB control values.

Work ing with XRef B ipeds
Using the XRef O bjects dialog (page 3–397),you
can externally reference bipeds in your scene.
This lets you work efficiently in a collaborative
environment because the changes that the artist
applies to his source XRef biped updates your
master scene content. See XRef Objects (page
3–394) for more information.
Externally R eferencing a B iped
When you create an XRef biped, certain modes
on the Motion Panel’s Biped rollout (page 2–936)
becomeunavailableasXRefdataisread-only:
• Figure Mode (page 2–982)
• Footstep Mode (page 2–988)
• Motion Flow Mode (page 2–1043)
• Mixer Mode (page 2–652)
As a result, you need to go back to the source scene
in order to make desired changes to your biped.
Example: Chang ing the Structure of a n Xref
Biped
An integrator externally references a biped into his
master scene. He discovers that the biped does not
have the right number of spine and neck links, and
