A new FCurves window has been added to MotionBuilder to be more consistent with other Autodesk applications. FCurves window
improvements include:
Multi-point editing
Multi-point editing was possible in previous releases of MotionBuilder. Now, this functionality has been visually enhanced
to be more consistent with other Autodesk applications.
Isolate selected curves
Quickly narrow your focus in the FCurves window by showing only the curves you want to work with. The new Isolate curve option
lets you easily view curves for selected channels only.
Auto tangent type
This new tangent type replaces the Bezier-Auto and Bezier-Clamp options. As you move keyframes in the FCurves window, Auto
tangents can automatically self-adjust to ensure smooth transitions, without overshooting maximum and minimum values. Auto
tangents can save animators valuable time when roughing out animation, as tangents are naturally adjusted to avoid creating
spikes.
The Auto tangent type is common to several other Autodesk applications, and is the default tangent type for new keys.
Simplified toolbar option
The FCurves contextual menu now includes a Classic Mode option which toggles the FCurves window between the classic, full
toolbar, and a more simplified toolbar that displays a smaller set of options. Switching off Classic Mode gives animators
who primarily use MotionBuilder as part of a suite a more streamlined display of curve editing tools.

Recording and storing vertex animation/point cache
MotionBuilder now supports the recording and playback of point cache data on models. Use point cache to boost performance
on animation intensive scenes or to transfer animation based on complex constraint or physics set-ups into other applications.
Enable recording through an option in the Model settings.
NotePoint cache is supported by the FBX file format.
Physx point cache recording
Physx point cache recording is only for Softbodies and Cloth and does not support Fluids.
Syncronization of animation with physics
A new physics solver property has been added. Enable ForceAnimationSync in the properties window when computation of the physics
takes longer than the animation.
NoteEnabling this property will restrict animation playback to occur only when physics is live. As a result, your animation playback
could be slower.
Time Code property
This property can be used with a time code generating device and allows you to associate time code to animation.
Up-vector property
Path constraints now have an option to set an up-vector. This option can be enabled in the properties window.
Real Time Filter operator
This Relations constraint operator applies a low-pass filter that allows filtering of live, incoming data. Real Time Filter
can be found in the Other section of the Relations constraint Object browser.
Displacement operator
This Relations constraint operator has been created to eliminate the dependency on display frame rates when using Relations
constraints with Physics. Displacement can be found in the Vector section of the Relations constraint Object browser.
