Sonic the Hedgehog (2006) 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.
