$basetexture

Usage

• $basetexture specifies the VTF texture to use for the basic 'skin' or diffusemap of the material surface.
• If the basetexture.vtf has an alpha channel (ie it's 32bit rather than 24bit) this can be used as luminositymap ($selfillum).

VMT syntax and default values

LightmappedGeneric
{
	$basetexture		"path/to/vtf"
	$basetexturetransform	"center .5 .5 scale 1 1 rotate 0 translate 0 0"
}

Available values

$basetexture

"$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.

$basetexturetransform

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

• Transforms the image from the base texture before use in the material.

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 horizontal X axis while the vertical Y axis is still at original scale.
3. rotate rotates the texture counter-clockwise in degrees. Accepts any number, including negatives.
4. translate shifts the texture by the given numbers. .5 will shift it half-way. 1 will shift it once completely over, which is the same as not moving it at all.

Note:All values must be included!

Bug:Scaling the texture may cause odd issues where the Texture Lock tool in Hammer will not actually lock the texture in place.  [todo tested in ?]

Bug:Rotating textures applied on brushes will rotate around the map origin (confirm: Orangebox engine only?). A fix for this is to change the center position in the VMT to the brush's origin.  [todo tested in ?]
