Patch

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 .

Example

patch
{
	include materials\models\infected\common\common_infected_shared.vmt
	insert
	{
		$basetexture models\infected\common\military_national_guard\common_military_upper_01
	}
}
