Introduction
The following a list of the shader fallbacks for the materials shipped with Half-Life 2. For a description of how shader fallbacks are used, see the Material choices and rendering performance in Controlling Geometry Visibility and Compile Times.
Shader Fallbacks
| LightmappedGeneric | |
|---|---|
LightmappedGeneric_dx9 |
dx9 |
LightmappedGeneric_dx8 |
dx8.0/dx8.1 |
LightmappedGeneric_NoBump_DX8 |
dx8.0/dx8.1, but only used when mat_reducefillrate 1 is set. Note that this fallback doesn't actually cause the shader code to do anything different, it's only there to allow a .VMT to specify different shader parameters or a fallback material when mat_reducefillrate 1 is set.

dx6/dx7 |
| VertexLitGeneric | |
VertexLitGeneric_dx9 |

| Refract | |
Refract_dx90 |
dx9 |
Refract_dx80 |
dx8.0/dx8.1 |
Refract_dx60 |
dx6/dx7: refraction isn't supported under dx6 and dx7, this fallback shader is only defined to allow you to use the $fallbackmaterial feature to cause the material system to use a different material under dx6 and dx7.
|
UnlitGeneric_dx6 |
dx6/dx7: If you neglect to define a fallback shader, unlit generic is used. |
| ShatteredGlass | |
ShatteredGlass |
dx9 |

dx7/dx6: this fallback shader is only defined to allow you to use the $fallbackmaterial feature to cause the material system to use a different material under dx6 and dx7.
|
LightmappedGeneric_dx6 |
dx7/dx6: This is used if you neglect to define a fallback shader. |
