A new Merge Base Animation Layers option has been added to the Import options to let you merge the base animation layer of an imported file with the base layer animation already in the scene. Turning this option on is useful when working with scenes where many assets are imported.
The default setting is off and imported layers are moved under the current base layer.
The new behavior is activated by setting the file command flag mbl/mergeBaseAnimLayer to True.
A new Neck Motion Reduction slider has been added to the Attribute Editor (HIKProperties > Retarget Specific area). Similar to the Neck Motion Reduction Properties in MotionBuilder, this attribute lets you dampen the amount of movement transferred from the character body to the neck. Neck Motion Reduction is useful when the motion created from inadequate capture data, and it works by averaging movement between the character's neck and chest.
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.
