$basetexture

The $basetexture shader parameter specifies the VTF texture to use for the basic 'skin' or diffusemap of the material surface.

Basic VMT Syntax

"$basetexture" "Path/TextureA" 

• where Path is the filepath relative to game_directory/materials folder.
• where TextureA is the filename; ie TextureA.vtf.
• Notice the .vtf file extension is not used in VMT texture references.

Additional Parameters

$basetexturetransform

"$basetexturetransform" "center <float> <float> scale <float> <float> rotate <float> translate <float> <float>"

• The default position is: "center .5 .5 scale 1 1 rotate 0 translate 0 0".
• "center" and "translate" are in UV 0.1 coordinates, "rotate" is in angles.
• Note: You must include all variables.

$basetexture2

"$basetexture" "Path/TextureA" 
"$basetexture2" "Path/TextureB" 
"$basetexturetransform2" "center <float> <float> scale <float> <float> rotate <float> translate <float> <float>"

• Used by the WorldTwoTextureBlend shader to blend materials on Displacement surfaces (terrain).
• The percentage blend of each of the two basetextures is defined by alpha painting in Hammer.
• The "$basetexturetransform2" line is not required; it's included just show that it is available.

$texture2

"$basetexture" "Path/TextureA" 
"$texture2" "Path/TextureB" 

• Used for the WorldTwoTextureBlend and UnlitTwoTexture shaders.
