 		[CanvasTexture] is an alternative to [ImageTexture] for 2D rendering. It allows using normal maps and specular maps in any node that inherits from [CanvasItem]. [CanvasTexture] also allows overriding the texture's filter and repeat mode independently of the node's properties (or the project settings).
-		[b]Note:[/b] [CanvasTexture] cannot be used in 3D rendering. For physically-based materials in 3D, use [BaseMaterial3D] instead.
