VMT Shaders/Parameters


Here you can see all .vmt file commands. Need more information on what VMT files are? Check out the tutorial section.
Dashed underlinesThat's right, dashed underlines just like this. mean a pop-up note is attached to the word, hover your mouse over it to read it.

Regarding Outlines of Use; brackets and their grey contents should not be used as shown. They should be replaced with appropriate values that can be seen from the 'Possible Values' sections. (Should the 'values' also be in grey, then just do as the 'values' instruct.) Quotation marks and file extensions (.vtf, etc.) aren't required on all commands, but they help to keep the .vmt file tidy, which in-turn helps prevent any possible mistakes.



VMT files are merely .txt files that have had their file extension renamed to become a .vmt file. These VMT files consist of 'shaders' and 'parameters', both of which define how a material is lit, and how/what it will do. The two most common shaders are "LightMappedGeneric" & "VertexLitGeneric". The former being used for map textures and the latter for model textures. Do not worry about placing capital letters in shader or parameter names, as they are not case-sensitive.

This is how a basic VMT is laid out (limited to one shader - excluding shader fallbacks for dx80 etc. - but loads of parameters can be used):
  • Example 
      "(Shader)"
{
	"(Parameter)" "(Parameter-value)"
}

    • This is what a common VMT used on a model will look like:
  • Example 
      "VertexLitGeneric"
{
	"$basetexture" "models/katharsmodels/vipermk2/vipermk2_sheet"
	"$envmapmask" "models/katharsmodels/vipermk2/vipermk2_mask"
	"$envmap" "env_cubemap"
}

  • "DecalModulate"
        About:
        Default shader used for decals. Decals are not fixed to the camera such as sprites are, but rather 'stick' to the world. For example, bullet-holes and blood are decals. You should also enter the '$decal' parameter (set to "1") inside the VMT when using this shader (Is this necessary? - or just for some kind of identification purpose).

        Compatible on Models:
        Possibly (see $model). It creates weird refraction-like effects.

        About:

        Compatible on Models:
        Possibly (see $model). It turns the model completely invisible, but I am unsure what this shader is supposed to do.

        Compatible on Models:
        Possibly (see $model). Displays the model's wireframe with a blue, additive material (Could be used for something sci-fi).
  • "GooingGlass"
        About:

        Compatible on Models:
        No.
  • "InternalFrameSync"
        About:

        No.
  • "JellyFish"
        About:

        Compatible on Models:
        Yes. (see $model) I haven't been able to get it fully working however, as it displays the debugging purple & black checkered texture over the $basetexture material. If you find out what the missing texture/command is, please let me know.
  • "Jojirium"
        About:

        Compatible on Models:

  • "ReflectTexture"
        About:

        Compatible on Models:
        No.
  • "Refract"
        About:

        Compatible on Models:
        Yes. (see $model & $dudvmap) Without a $dudvmap, it turns the model into some kind of 'window' which just displays its basetexture.

        Compatible on Models:
        Yes (see $model).
  • "TranslucentLightMap"
        About:

        Compatible on Models:

        About:
        Renders the texture to display no lighting detail. (the equilivent of 100% Self-Illumination or running mat_fullbright 1) If used on a model, you must declare the following parameter; '$model' (set to "1") - else the model will just appear as a wireframe.

        Compatible on Models:
