 				Returns [code]true[/code] if the node is present in the [SceneTree], its [member visible] property is [code]true[/code] and all its ancestors are also visible. If any ancestor is hidden, this node will not be visible in the scene tree, and is therefore not drawn (see [method _draw]).
 				Visibility is checked only in parent nodes that inherit from [CanvasItem], [CanvasLayer], and [Window]. If the parent is of any other type (such as [Node], [AnimationPlayer], or [Node3D]), it is assumed to be visible.
+				[b]Note:[/b] This method does not take [member visibility_layer] into account, so even if this method returns [code]true[/code] the node might end up not being rendered.
