 Specular maps hold information on how an object reflects light. It is sometimes also referred to as a gloss map. Lighting is games does not reflect the true behaviour of light in the real world, thus specular highlights are used to give the illusion of light reflecting off a surface. In simplest terms, it denotes the size and intensity of bright spots on an object, places where light would reflect back in the real world. Objects that should appear very shiny, like polished metal, have high sharp specular highlights, objects that should appear fairly dull, like cloth, have low flat specular highlights.
-Specular maps function in a manner not dissimilar to alpha masks, in that the closer to white an area it is, the brighter the highlight. They appear to function as a container file, holding 4 greyscale specular maps, one in each channel.
+Specular maps function in a manner not dissimilar to alpha masks, in that the closer to white an area it is, the brighter the highlight. This information is stored in alpha channel of the specular map. The RGB part of the map defines tint applied to the highlight, as not all materials reflect the light equally -- some can reflect the color of the light source, while for others this will be the color of the reflecting object. The tint helps to simulate the latter behavior.

 === Diffuse Map ===
-This texture holds the base colour information for the model. Diffuse maps are commonly referred to as "skins" in other games. Diffuse maps can be enhanced through the use of the [[Material Tint System|tint system], which overlays a series of colours (defined by the [[TNT]] file) on the diffuse map in a pattern defined by the associated tint map.

 RGB channels - These hold the colour information, as with any standard image.
