Sonic the Hedgehog (2006) Shaders

Shaders

These shaders are stored in game/xenon/archives/shader.arc and game/xenon/archives/shader_lt.arc in the 360 version of the game. Most shaders have several different variants with different feature support. Shaders in shader_lt.arc are used in multiplayer and may have additional optimisations, like replacing real-time planar reflections with cubemaps.

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 subfolders will be 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 XNOs. Some shaders are not referenced in XNOs, either because they are used internally or because they are unused altogether.
