"$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.

"$additive" 1

Renders the texture additively (Its colors are added to, instead of replacing, what is displayed behind it).

"$alpha" <float>

Scales material opacity by the 'float' number.
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.(see $alphatest)

- "$alpha" float
-* Scales material opacity by the 'float' number.
-====$alphatest====
-Sometimes [[$translucent]] leads to rendering errors in the game: eg where modelA is behind modelB, but modelB gets hidden by modelA. If this happens, using the command <code>"$alphatest" 1</code> instead of <code>"$translucent" 1</code> should fix it.
-* VMT syntax example:
-       // "[[$translucent]]" 1
-       "[[$alphatest]]" 1
-* Every pixel with an alpha value less than 178 will be completely transparent in game. (However, values close to this value will confuse the shader at distances.)
-* This type of shading costs much less than [[$translucent]] shading.
