| They are used to bend the surface normal when shading, resulting in a relief like change of the shading that is very similar to the effects of a bump map (( A bump map is more or less a simplified variant of a normal map. When rendering, normals are derived from the bump map. )). | They are used to bend the surface normal when shading, resulting in a relief like change of the shading that is very similar to the effects of a bump map (( A bump map is more or less a simplified variant of a normal map.

You can also selectively invert the directions on a per channel basis. | These controls allow you to assign any of the channels present in the current infiniMap image to be used as X, Y or Z.
