$basetexture

From Valve Developer Community

The $basetexture VMT command defines an albedo texture. It is very rare for a material not to use this command.

VMT syntax

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

LightmappedGeneric
{
	$basetexture	brick\brickwall031b
}

Additional parameters

$basetexturetransform <matrix>

Transforms the texture before use in the material. Requires DirectX 9.

The default position is "center .5 .5 scale 1 1 rotate 0 translate 0 0".

1. center defines the point of rotation. Only useful if rotate is being used.
2. scale fits the texture into the material the given number of times. '2 1' is a 50% scale in the X axis.
3. rotate rotates the texture anti-clockwise. Accepts any number, including negatives.
4. translate shifts the texture by the given number of heights/widths. '.5' will shift it half-way.

 Note: All values must be included!

$basetextureoffset <normal>

To do: DX8 version of translate?

$basetexturescale <normal>

To do: DX8 version of scale?

$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
• To do: $basetextureoffset2 <normal>?
• To do: $basetexturescale2 <normal>?

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