== From Theory to Practice ==

* Artists paint unlit surface features and properties into textures.
* Specular colors have been determined from measured Indices of Refraction.
* Diffuse colors have been measured using cross polarization photographic techniques and analysis of various color spaces.
* ALL TEXTURES MUST BE AUTHORED IN 16bit!!!
* Everyone must leave room for everyone else.
* There should be minimal duplication of information.

== Authoring Normal Maps ==

* This is the most important map of the bunch. Highest resolution, most detail.
* Bake from a high-poly. model with your package of choice.
* We compute variance based on the roughness represented in the normal and modify gloss.
* Detail normal maps should beused to represent anything smaller than 1/8th of an inch. Detail normal maps contribute to gloss variance as well.

== Authoring Diffuse Textures ==

* No values below 40, none above 238. This leaves room for lighting.
* Exception: In the case of a pure metal, this map should be completely black.
* Start with a flat color swatch to represent the unlit base color, or reflectance, of your surface.
* Do not paint AO or highlights of any kind into the diffuse map.

== Authoring Specular Textures ==

* Most of the time you should be skipping this step.
* In the case of a surface with bare metal showing, you can create a specular mask.
* Start with a white texture and paint all the parts that are not pure metal black.
* Touch up the areas around your metallic areas with grayscale values to simulate some dust coverage, or light pitting.

== Authoring Gloss Textures ==

* Start with a fully white texture, to represent the glossiest that your surface will be.
* Set the gloss range in APE to the appropriate surface type.
* If the presets in APE don’t work, you can select custom and dial in the high and low gloss thresholds to suit your full range map.
* Paint the least glossy parts of this texture completely black.
* There is a separate power point that goes into further detail on gloss maps.

== Authoring AO Textures ==

* Bake these with your favorite tool, just make sure they aren’t too dark.
* There should not be AO across your entire surface, this will make your model get very dark in shadow and look flat.
* AO only affects the indirect lighting: reflection and bounced diffuse. Otherwise, your model would look like it had creepy moustache growing all over it.
