= SYMPTOMS =

You have saved keys for an object’s explicit translation, then plotted the object’s velocity. The object with the plotted velocity is then used as an Expression element with a ‘velx’ Fcurve (exp_element.velx).

The problem is apparent when the Y rotation of the affected element does not behave according to the velocity Fcurve of the Expression element.

= CAUSE =

Although the velocity of the object used as the Expression was plotted, the velocity Fcurve in reality is not a true one.

= RESOLUTION =


 * 1) Apply a QStretch property to the Expression element (Velocity -> flex with a maximum of 0.0 and sensitivity of 0.0).
 * 2) Plot the velocity for the Expression element.
 * 3) Playback the animation or translate the Expression element. The affected element now behaves according to the Expression’s velocity Fcurve.

= STATUS =

This behavior is by design.
