The Graph Editor has had the following updates and improvements.
Peak Removal Filter to clean up noisy animation data
A new animation filter, the Peak Removal Filter, has been added to the Graph Editor Curves menu. Similar to the MotionBuilder filter of the same name, the Peak Removal Filter lets you clean up unwanted spikes and peaks in your animation curves, replacing them with keys averaging their values on neighboring keys.
This filter has options to isolate the whole of the animation. or only a section of it, and a Preview setting to let you view the effect of the filtering before applying.
Smooth filter (Gaussian) for curve "noise" reduction
The Smooth filter (Gaussian) applied to a single channel
Another new MotionBuilder filter, the Smooth filter (Gaussian) has been added to the Graph Editor Curves menu, to let you remove jittering and noise in curve channels. See Smooth filter (Gaussian) options for details.
New display option
A new Show Animated Shapes option in the Graph Editor List menu lets you set whether the Graph Editor displays all curves downstream from a node, or just the animation curve of the selected node. This is useful if you have custom rigs with specialized connections or when animators only want to view the transforms for a selected object.
Preserve Tangent Type: Now for Added Keys
The Preserve Tangent Type option, formerly only for Inserted Keys, is now available for Added Keys.
Previously, when you added a key to a curve, by default, the new key respected the tangents on either side of the key. This ensured that added keys did not change the neighboring tangents type while still changing the shape of the curve. This behavior continues to be the default setting.
Preserve Tangent Type for Added keys: on (default)
We present this new option so that the shape of the curve is preserved when you add a key. If you disable the Preserve Tangent Type option, newly-added keys change neighboring tangents to "fixed", but do not affect the shape of the curve.
Preserve Tangent Type for Added keys: off
Customize Key Selection
A new preference has been added so you can shrink the active selection area of keys in the Graph Editor graph view. Use Min key selection size in the Animation (Settings) preferences if drag-selecting keys unintentionally includes keys outside the selection range. Changing this preference can be useful when you work with the Graph Editor at reduced size and/or have scenes with dense animation.
