		Editor-only helper for setting up root motion in [AnimationTree].
	</brief_description>
	<description>
		[i]Root motion[/i] refers to an animation technique where a mesh's skeleton is used to give impulse to a character. When working with 3D animations, a popular technique is for animators to use the root skeleton bone to give motion to the rest of the skeleton. This allows animating characters in a way where steps actually match the floor below. It also allows precise interaction with objects during cinematics. See also [AnimationTree].
		[b]Note:[/b] [RootMotionView] is only visible in the editor. It will be hidden automatically in the running project, and will also be converted to a plain [Node] in the running project. This means a script attached to a [RootMotionView] node [i]must[/i] have [code]extends Node[/code] instead of [code]extends RootMotionView[/code]. Additionally, it must not be a [code]@tool[/code] script.

			The grid's radius in 3D units. The grid's opacity will fade gradually as the distance from the origin increases until this [member radius] is reached.

			If [code]true[/code], the grid's points will all be on the same Y coordinate ([i]local[/i] Y = 0). If [code]false[/code], the points' original Y coordinate is preserved.
