$desaturatewithbasealpha is a material shader parameter for the VertexLitGeneric shader available in all Source games since Alien Swarm.
Setting it to a value above 0 will enable the behavior.
If used, the $basetexture's Alpha channel will be used as a mask to de-saturate the $basetexture's Color.
The amount of desaturation is determined through the same parameter. 1.0 will result in 100%, and 0.5 in 50% desaturation.

Todo: Is this available since

?

Note:Also available for use in

and

through

LUX

Caveats

Bug:This Parameter does not work with

$seamless_base. (this works in )
$detail. (this works in )
$bumpmap or any parameters that requires a $bumpmap. Including $lightwarptexture. (this works in )
$selfillum and thus $selfillummask (this works in )
$selfillum_envmapmask_alpha. (this works in )
$basealphaenvmapmask. (this works in ) [todo tested in ?]

Warning:Using the Basetexture's Alpha channel for other effects at the same time might result in unexpected behavior!
