Application with and without
$blendmodulatetexture.WorldVertexTransition is the shader used to blend the vertices of a displacement surface between two different albedos. It handles two at once by using a mirrored set of parameters with "2" in their name.
The pattern of the blend is defined by Hammer's alpha painting tool. The blend is normally a linear gradient, but it can also be "stamped" by a texture specified with $blendmodulatetexture. This command makes the material look considerably better for very little cost - use it often!
Note:This shader now only works on displacements.Example
WorldVertexTransition
{
$basetexture nature/dirtfloor006a
$surfaceprop dirt
$basetexture2 nature/rockfloor005a
$surfaceprop2 rock
%tooltexture nature/blendrockgrass004a_tooltexture
}
- Just about all visual effects can be selectively applied to one sub-material or the other. See the relevant articles for more details.
- The Hammer material browser won't be able to display a preview of the material unless it's given a
%tooltexture.
