Animation Layers

Edit your animation or mocap data quickly using a standard animation layers UI and workflow directly in your 3D viewport with an extra layers functionality.

Animation Layers is an addon that simplifies the work with the NLA Editor into a standard animation layers workflow. You can quickly create, select and edit each layer, and always seeing the end result while working on any layer.

Add or Remove Layers quickly, or control their Influence using NLA's Mute, Influence, Solo and its Blending modes options.
When you are happy with your animation, you can always merge your layers or bake into a new layer.
Use 'Smart Bake' to keep the same amount of the overall keyframes after baking.

Animation Layers offers also tools such as
'Select bones in layer', 'Reset key layer', Layer breakdowner, Share layer keys, Multikey, Extract bones, Extract from Markers.
And also simplified nla settings such as Custom Frame Range, Speed and Offset.
