 			Texture used to specify the normal at a given pixel. The [code]normal_texture[/code] only uses the red and green channels; the blue and alpha channels are ignored. The normal read from [code]normal_texture[/code] is oriented around the surface normal provided by the [Mesh].
 			[b]Note:[/b] The mesh must have both normals and tangents defined in its vertex data. Otherwise, the normal map won't render correctly and will only appear to darken the whole surface.
