Basic VMT syntax
"$translucent" 1
- Used with UnlitGeneric, VertexLitGeneric, LightmappedGeneric and many more shaders to enable a opacity map according to the alpha channel of the $basetexture.
- Warning: There are reports of a Rendering bug which reverses the overlay order of multiple translucent materials; so that the further material occludes the nearer one. The preferred solution appears to be to use $alphatest instead or $translucent.
Additional Parameters
$alpha
"$alpha" float
- Scales material opacity by the 'float' number.
$alphatest
"$alphatest" 1
- Every pixel with an alpha value less than 178 will be completely transparent in game. (However, values close to this value will confuse the shader at distances.)
- This type of shading costs much less than $translucent shading.
$additive
"$additive" 1
- Renders the texture additively (Its colors are added to, instead of replacing, what is displayed behind it).
