== Shaders ==
'''''Shaders''''' in [[Sonic the Hedgehog (2006)]] are compiled GPU programs that control the appearance of objects and effects. Most shaders have several different variants with different feature support. Multiplayer shaders may have additional optimisations, like replacing real-time planar reflections with cubemaps.


These shaders are stored in <code>game/xenon/archives/shader.arc</code> and <code>game/xenon/archives/shader_lt.arc</code> in the 360 version of the game. Most shaders have several different variants with different feature support.
In the Xbox 360 version of the game, shaders are stored in the following [[U8 Archive|archives]]:
{| class="wikitable" style="margin: auto;" width="90%"
{| class="wikitable"
|+
!Type
!Location
|-
|Singleplayer
|<code>/game/xenon/archives/shader.arc</code>
|-
|Multiplayer
|<code>/game/xenon/archives/shader_lt.arc</code>
|}
Within the archives, shaders are stored in a number of sub-folders.

Many of the shaders within the sub-folders are exact duplicates of the standard variant.


Each of the shaders listed below are in the <code>.fxo</code> format in the 360 version of the game. Each shader can contain multiple techniques, which hold the respective vertex and fragment shaders.

Shaders in Sonic the Hedgehog (2006) are compiled GPU programs that control the appearance of objects and effects. Most shaders have several different variants with different feature support. Multiplayer shaders may have additional optimisations, like replacing real-time planar reflections with cubemaps.

In the Xbox 360 version of the game, shaders are stored in the following archives:

Type Location
Singleplayer /game/xenon/archives/shader.arc
Multiplayer /game/xenon/archives/shader_lt.arc

Within the archives, shaders are stored in a number of sub-folders.

Folder Description
lm Lightmapped
lm_np Lightmapped without point lights
morph Mesh morph
morph_np Mesh morph without point lights
skin Rigged meshes
skin_np Rigged meshes without point lights
std Standard
np Standard without point lights

Many of the shaders within the sub-folders are exact duplicates of the standard variant.

Each of the shaders listed below are in the .fxo format in the 360 version of the game. Each shader can contain multiple techniques, which hold the respective vertex and fragment shaders.

The shader and specific technique used are defined per mesh set in XNO files. Some shaders are not referenced in XNO files, either because they are used internally or because they are unused altogether.
