Shaders in Nature\

The Nature\ folder of hl2_misc_dir.vpk contains the following shaders:

• LightmappedGeneric is used for 71 materials.
• LightmappedGeneric_DX9 is used for 5 materials (as a fallback shader for LightmappedGeneric and WorldVertexTransition).
• Water is used for several materials.
• UnlitGeneric is used for the tree_card_clump.vmt and the water_movingplane_beneath.vmt materials.

Dedicated Shaders

The following shaders are more or less exclusively used for this folder.

Cloud

• Only used by the cloud001c.vmt material. Also used by 2 materials in the shadertest\ folder.
• Not found in released mod code.

LightmappedGeneric_DX6

• Used by the materials toxicslime002a.vmt and water_movingplane.vmt as a fallback shader for LightmappedGeneric. Also used in the Dev\ and Glass\ folders.
• Referred to twice in src\materialsystem\stdshaders\lightmappedgeneric_dx8.cpp in the released mod code.

Water_DX60

• Used by 22 materials (as a fallback shader for the Water shader) in this folder. Also used in the Dev\ folder to a lesser extent.
• Referred to in src\materialsystem\stdshaders\water_dx60.cpp and src\materialsystem\stdshaders\water_dx80.cpp in the released mod code.

Water_DX80

• Used by 19 materials (as a fallback shader for the Water shader) in this folder only.
• Defined in src\materialsystem\stdshaders\water_dx80.cpp in the released mod code.

Water_DX81

• Used by 15 materials (as a fallback shader for the Water shader) in this folder only.
• Defined in src\materialsystem\stdshaders\water_dx81.cpp in the released mod code.

Water_DX90

• Only used by 3 materials in this folder. Also used by the dev_water3.vmt material in the Dev\ folder.
• Defined in src\materialsystem\stdshaders\water.cpp in the released mod code.
• Remarks from Valve: "Only used in dx90 and higher", "NOTE: These are only used by DX9 water, since forceExpensive isn't defined.", "ALSO NOTE: This *cannot* exist in the root level, because the presence of this is used to determine whether to do the reflection in the client DLL"

WorldVertexTransition

• Used by 46 materials in this folder. Also used in the Concrete\ and Dev\ folders, to a much lesser extent.
• Mostly used in materials starting with "blend".
• Probably referred to in released mod code.
• See WorldVertexTransition for more information.

WorldVertexTransition_DX9

• Used only in the canal_reeds.vmt material (as a fallback shader for the WorldVertexTransition shader).
• Not found in released mod code.
