This is list of the shader fallbacks that shipped with Half-Life 2. See Material optimization and DirectX Versions for more details.

Note:These DirectX shader fallbacks have been removed and replaced by the shader and effect detail systems since <Left 4 Dead> Left 4 Dead.

LightmappedGeneric

LightmappedGeneric_HDR_DX9 
DX9 with HDR
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 (usually by dxsupport.cfg). Note that this fallback doesn't actually cause the shader code to do anything different, it's only there to allow a material to specify different parameters.
LightmappedGeneric_DX6 
DX6, DX7

VertexLitGeneric

VertexLitGeneric_HDR_DX9 
DX9 with HDR
VertexLitGeneric_DX9 
DX9
VertexLitGeneric_DX8 
DX8.0, DX8.1
VertexLitGeneric_DX7 
DX7
VertexLitGeneric_DX6 
DX6

UnlitGeneric

UnlitGeneric_DX9 
DX9
UnlitGeneric_DX8 
DX8.0, DX8.1
UnlitGeneric_DX6 
DX6, DX7

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
ShatteredGlass_DX8 
DX8.0, DX8.1
ShatteredGlass_DX7 
DX7
Wireframe 
DX6: Shattered glass isn't supported under DX6.

Water

Water_HDR_DX90 
DX9 with HDR
Water_DX90 
DX9
Water_DX81 
DX8.1
Water_DX80 
DX8.0
Water_DX60 
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.

WorldTwoTextureBlend

WorldTwoTextureBlend

WorldVertexAlpha

WorldVertexAlpha 
DX9
WorldVertexAlpha_DX8 
DX8.0, DX8.1: Note this shader has no fallbacks to DX7 or below.
