• 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.
