Filters list

Choose the filter to use from this drop-down list.

The available filter types include smoothing, blurring, boosting, key reduction, and subanims.

• Rot filters work in quaternion rotation space, and modify the quaternions of the specified animation tracks.
• Pos filters work in the specified positional coordinate system, and modify the positions of the animation tracks.
• BlurringUses basic Gaussian filters that take a weighted average over the width. Blurring filters are good for smoothing out noise, but can also over-smooth areas that aren't noisy.

  See Blurring, Smoothing, and Boosting parameters, below.

• Smoothing filters, on the other hand, are much better than blurring filters for keeping the general shape of the track or curve. They affect only areas that have big changes. The drawback of the smoothing filters is that they don't change the curve as dramatically as the blurring filters do, so sometimes you'll need to run the smoothing filter multiple times to smooth out a particularly noisy area.
• Adv Rot Smoothing works even better than the normal angular smoothing filter when it comes to modifying only large changes and not small ones.

  See Blurring, Smoothing, and Boosting parameters.

  (There is no comparable “advanced position” fixer or filter.)

• BoostingBoosting filters are the opposite of blurring filters. They increase, rather than decrease, changes in the track. Boosting filters are helpful if you want to make a track have more exaggeration or a little more jerkiness.

  See Blurring, Smoothing, and Boosting parameters.

• Sub AnimsThe Sub Anims filter manages sub-animation of biped objects. Clicking a button that corresponds to a transform (Position, Rotation, or Scale) displays a dialog that lets you assign a controller to that transform. Assigning a controller in this way assigns it only to the selected biped parts. This is very handy for adding controllers to multiple biped parts all at once. Also includes the ability to enable or disable the three list controllers selectively, and avoids creating SubAnims, where they already exist.

  See Sub Anim parameters.

• Key Reducer Creates tracks with fewer keys, by removing certain keys based on tolerance and key spacing parameters. This works similarly to how key reduction works during motion-capture import.

  See Key Reducer parameters.

• Knee Wobble Corrects knees that wobble or shake when a foot is planted. If the knee is determined to wobble by the filter, the center of mass object is adjusted to eliminate the wobble.
• Knee ExtensionCorrects knees that overextend when a foot is planted. If the knee extension is identified by the filter, the center of mass object is adjusted to eliminate the extension.

Blurring, Smoothing, and Boosting parameters

Width

Width is the size of the filter kernel width in frames. It tells you how much of the animation is taken into effect when filtering a specified keyframe.

Damping

The Damping value changes how effective the filter should be. A higher value, the more dramatic the change. A damping value of 1.0 is normal filter behavior

Sub Anim parameters

Enable

Turns Position, Rotation, and Scale subanims on and off for the selected biped parts.

Collapse

Adds the subanim animation of the selected biped part to that part’s Transform controller.

NoteWhen you choose the Sub Anims filter, the Filter button at the bottom of the panel disappears. That's because the operations of this filter are immediate.

Don’t Delete

Maintains the subanim in the list as it’s collapsed onto the biped.

Per Frame

Sets keys at every frame of the collapsed controller.

The Sub Anims filter tools are also available from the Motion panel. You can assign controllers to a biped subanim, and then collapse it by right-clicking and choosing Properties. The difference between using this in the Motion panel and in the Workbench is that you can apply subanims to multiple biped objects in one step when using the Workbench filter.

Key Reducer parameters

Create Key Per Frame

When on, the filter creates a key per frame for every selected track. Default=off.

Tolerance

Sets the maximum angular or positional deviation for a track (other than a COM track). Default=3.0.

Values are in units of translation for position tracks, and in degrees for rotation tracks.

Key Spacing

Sets the minimum number of frames between keys (other than COM keys).

Tolerance is computed first, then Minimum Key Spacing computes further key reduction.

COM Parameters

These Tolerance and Key Spacing settings affect key reduction only on specified center-of-mass (COM) tracks (horizontal, vertical, or rotational).
