$basetexture2

Usage

• A second basetexture is used in combination with $basetexture for blending two materials on a brush displacement surface.
• Used by the WorldVertexTransition shader to blend materials on Displacement surfaces (terrain).
• The percentage blend of each of the two basetextures is defined by alpha painting in Hammer.
• See Displacement for further information.

VMT syntax and default values

"WorldVertexTransition"
{
   "$basetexture" "Path/TextureA" 
   "$basetexture2" "Path/TextureB" 
     "$basetexturetransform2" "center .5 .5 scale 1 1 rotate 0 translate 0 0"
}

Available values

$basetexture2

"$basetexture" "Path/TextureA" 
"$basetexture2" "Path/TextureB" 

• where Path is the filepath relative to game_directory/materials folder.
• where TextureA is the 1st basetexture filename; ie TextureA.vtf.
• where TextureB is the 2nd basetexture filename; ie TextureB.vtf.

$basetexturetransform2

"$basetexturetransform2" "center <float> <float> scale <float> <float> rotate <float> translate <float> <float>"

• Used with $basetexture2 by the WorldVertexTransition shader to blend materials on Displacement surfaces (terrain).

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 ?]
