 	<description>
-		Spatial is the base for every type of 3D [Node]. It contains a 3D [Transform] which can be set or get as local or global. If a Spatial [Node] has Spatial children, their transforms will be relative to the parent.
+		Most basic 3D game object, with a 3D [Transform] and visibility settings. All 3D physics nodes and sprites inherit from Spatial. Use Spatial as a parent node to move, scale, rotate and show/hide children in a 3D project.
