Note:If a material with this shader is used on a non-displacement surface, the Source engine will generate a warning, saying that support for this is going away soon. However, the warning incorrectly calls the shader "WorldTwoTextureBlend". It should also be noted that this warning has been there for a couple of years - see Valve Time.

- Used to blend materials on Displacement surfaces (terrain).
- The percentage blend of each of the two textures is defined by alpha painting in Hammer.
- Two basetextures are vertex lit.
Basic VMT Syntax
(from ep2/materials/nature/blendgrassdirt01.vmt)
"WorldVertexTransition"
{
"$basetexture" "nature/forest_grass_01"
"$basetexture2" "nature/forest_dirt_02"
"$surfaceprop" "dirt"
"$blendmodulatetexture" "nature/blendtexture01"
"%detailtype" "forest_floor_01"
}
Additional Parameters
- Use $basetexture2 and $bumpmap2 to define the second material.
Note:If a material with this shader is used on a non-displacement surface, the Source engine will generate a warning, saying that support for this is going away soon. However, the warning incorrectly calls the shader "WorldTwoTextureBlend". It should also be noted that this warning has been there for a couple of years - see Valve Time.
