$basetexture

$basetexture is a material shader parameter available in all Source games. It defines a diffuse texture. It is very rare for a material not to use this parameter and some shaders will load a default texture if it stays undefined.

VMT Syntax

$basetexture	<texture without extension, relative to <game>\materials\>

LightmappedGeneric
{
	$basetexture	brick\brickwall031b
}

Additional Parameters

$basetexturetransform

$frame

$basetexture2

Some shaders (most notably WorldVertexTransition) allow the use of two albedos. The second texture is handled by a mirrored set of commands with '2' in their name:

$basetexture2

$basetexturetransform2

$frame2

There are further '2' commands applying to various shader effects, which are each documented in their respective articles.
