 		[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.
