 		[AnimatedSprite2D] is similar to the [Sprite2D] node, except it carries multiple textures as animation frames. Animations are created using a [SpriteFrames] resource, which allows you to import image files (or a folder containing said files) to provide the animation frames for the sprite. The [SpriteFrames] resource can be configured in the editor via the SpriteFrames bottom panel.
 		After setting up [member frames], [method play] may be called. It's also possible to select an [member animation] and toggle [member playing], even within the editor.
 		To pause the current animation, set [member playing] to [code]false[/code]. Alternatively, setting [member speed_scale] to [code]0[/code] also preserves the current frame's elapsed time.
-		[b]Note:[/b] You can associate a set of normal or specular maps by creating additional [SpriteFrames] resources with a [code]_normal[/code] or [code]_specular[/code] suffix. For example, having 3 [SpriteFrames] resources [code]run[/code], [code]run_normal[/code], and [code]run_specular[/code] will make it so the [code]run[/code] animation uses normal and specular maps.
