Patch is a Pixel shader available in all 
Source games. It is a special shader that allows materials to inherit from each other. This is achieved with two commands:
include- The base material from which to inherit.
Note:The complete path is required, including materials\and .vmt. insert- The parameters to add, inside
{and }. Those that already exist are overridden.
Tip:<parameter> ""can be used to remove an established value. replace- The parameters to replace, inside
{and }.Todo: Check if this is Orange-Box only. Seen in
and 
.
Patch's only limitations are that it cannot change a material's shader, and a Patch material cannot use include to inherit from another Patch material.
- Note:Patch material including other Patch materials seems to work fine in
and 
. The "The Last Stand" update added wounded L4D1 infected materials, which include their default materials, which in turn include the shared material.
Example
patch
{
include materials\models\infected\common\common_infected_shared.vmt
insert
{
$basetexture models\infected\common\military_national_guard\common_military_upper_01
}
}
