TIP When creating a mixdown, you can preserve your Euler tangents by turning
on A Keyframe Per Frame in the
Mixer Preferences dialog on page 3741.
Motion Flow follows the same rules as the Motion Mixer. If clips brought into
Motion Flow contain Euler animations, their tangents are preserved. However,
creating an unified motion results in a quaternion animation.
TIP Euler tangents can be preserved when creating a unified motion by turning
on A Keyframe Per Frame in the Unify Options dialog (by clicking Create Unified
Motion in the Motion Flow Scripts Group on page 4554).
Turn on A Keyframe Per Frame to preserve Euler tangents.
Copy-Pasting Data between Euler and Quaternion Curves
When you copy a track and paste it onto another, its type (Euler or quaternion)
is pasted as well. This sometimes results in animations switching from
quaternion to Euler and vice-versa.
Euler tangents of copied poses or postures are never copied. If you copy an
Euler track and paste it onto any type of track with Auto Key turned on, the
current TCB or tangent values (depending on the type of track onto which
you pasting) are ignored and instead set to Default .
Following the same rule, pasting a pose or posture on a Euler track with Auto
Key turned on doesn't transfer the TCB values of the copied track. If a new
key is created before pasting the track, the resulting tangent is set to Default.
