== 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. Shaders in <code>shader_lt.arc</code> are used in multiplayer and 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 [[U8 Archive|archives]]:

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

Many of the shaders within the subfolders will be exact duplicates of the standard variant.
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.

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

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 variants are stored in a number of sub-folders.

Folder Description
std Standard
np Standard without point lights
lm Replaces CSM with baked lightmaps and shadows.
lm_np Same as lm without point lights
morph, morph_np Morph targets (only affects vertex shaders)
skin, skin_np Skined meshes (only affects vertex shaders)

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.

Shader Inputs

All shaders used for rendering 3D objects use a common input block format.

Registers Parameter Description
c0-c3 g_Material NinjaNext material parameters. Not always used as described.
c4 g_Misc
c5-c6 g_OffsetUV
c8-c13 g_OLS Hoffman–Preetham scattering parameters. Most shaders evaluate phase at constant cos(θ) = 0.5.
