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.
LightmappedGeneric_dx6	dx6/dx7

VertexLitGeneric

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_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	dx9
WorldTwoTextureBlend_dx8	dx8.0/dx8.1
WorldTwoTextureBlend_dx6	dx6/dx7

WorldVertexTransition

WorldVertexTransition_dx9	dx9
WorldVertexTransition_dx8	dx8.0/dx8.1
WorldVertexTransition_dx6	dx6/dx7

WorldVertexAlpha

WorldVertexAlpha	dx9
WorldVertexAlpha_dx8	dx8.0/dx8.1: Note this shader has no fallbacks to dx7 or below.

Cable

Cable	dx8.0/dx8.1/dx9
UnlitGeneric_DX6	dx6/dx7

Eyes

Eyes	dx8.0/dx8.1/dx9
Eyes_dx6	dx6/dx7

Modulate

Modulate	dx8.0/dx8.1/dx9
Modulate_dx6	dx6/dx7

MonitorScreen

MonitorScreen	dx8.0/dx8.1/dx9
LightmappedGeneric_dx6	dx6/dx7

Predator

Predator_dx80	dx8.0/dx8.1/dx9
Predator_dx60	dx6/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: This is used if you neglect to define a fallback shader.

Sprite

Sprite_dx8	dx8.0/dx8.1/dx9
Sprite_dx6	dx6/dx7

UnlitTwoTexture

UnlitTwoTexture	dx8.0/dx8.1/dx9
UnlitTwoTexture_dx6	dx6/dx7

WriteZ

WriteZ	dx8.0/dx8.1/dx9
WriteZ_dx6	dx6/dx7

WindowImposter

WindowImposter_dx80	dx8.0/dx8.1/dx9
WindowImposter_dx60	dx6/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: This is used if you neglect to define a fallback shader
