Materials consist of:

Materials consist of:

* Base texture, which is a mostly grayscale texture that can be colored by the player

* Base texture, which is a texture that can be colored by the player. This should be grayscale most of the time, as the player chosen color will be applied directly by multiplying it, except as noted for the Extra texture.

* Bump texture, which is the usually purple tinted normal map

* Bump texture, which is the normal map, these are usually purple, signifying a direction pointing along the normal of the surface.

* Extra texture. The material uses the 3 color channels of the extra texture to modify the material. The red channel controls occlusion, i.e. how dark a material appears, even direct light, to simulate crevices, the green channel controls smoothness/specularity and finallyt the blue channel controls color masking, where 100% blue means the player's color will be 100% multiplied with the base texture color and 0% means the material will only use the base texture color. An example of using the blue channel of the Extra texture would be to add gold adornments to a wall that the player can't change the color of.
