WorldVertexTransition

• 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

worldtwotextureblend ?

Additional Parameters

• Use $basetexture2 and $bumpmap2 to define the second material.

Note: that support for using this on a non-displacement surface will go away "soon", although it should also be noted that this is in Valve Time.
