Bake to Root is a lightweight utility plugin designed to bake the animation, of any character, from the hip bone to the root bone.

A Bake to Root Editor Widget is used to allow the Bake to Root features to work on any character. In the widget, you can set the skeleton and then select the hip and root bones of your choice.

There are Mixamo specific Scripted Asset Actions that allow quick solutions to adding a root bone and baking the motion to the root. This works on selected Mixamo skeletalMeshes and animSequences in the content browser.

For the widget, a menu item has been added to the Tools menu, in addition to there also being a scripted asset action to start the widget.
