Half-Life 2 Shader Fallbacks

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. Furthermore, Source 2013 also no longer support anything below DirectX 8, so it would be unnecessary to create shader fallbacks below DX8.

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.

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_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.
