Source Engine Shader Fallbacks

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_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

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

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

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
