Template:Shaderparam It specifies a texture which Source will use to add high-resolution detail to a material when it is viewed up close, by darkening or lightening the albedo appropriately, depending on the $detailblendmode. You can also use a full color (as opposed to grayscale) image and blend it using $detailblendmode 2. It is very effective for increasing the apparent resolution of a texture, and was used extensively in Episode Two.
Bug:Detail textures do not currently work in conjunction with $seamless_scale. Enabling them to work together would require a programmer to edit the used shader. [todo tested in ?]Syntax
$detail <texture>
You will probably want to use at least $detailscale (see below) as well.

Valve's detail textures
Valve's stock detail textures (available in OB only) are best used with the following pre-configured values:
$detail detail\noise_detail_01 // e.g. for brickwork, concrete... $detailscale 7.74 $detailblendfactor 0.8 $detailblendmode 0
$detail detail\metal_detail_01 $detailscale 4.283 $detailblendfactor .65 $detailblendmode 0
$detail detail\rock_detail_01 $detailscale 11 $detailblendfactor 1 $detailblendmode 0
$detail detail\plaster_detail_01 $detailscale 6.783 $detailblendfactor .8 $detailblendmode 0
The below parameters come from models\props_forest\LadderWood.vmt
It is the only Valve Stock texture VMT file to use this particular detail texture.
Because the detail texture (detail\wood_detail_01) is a high resolution (1024x1024), the $detailscale is lower than the others. With the exception of rock_detail_01.
$detail detail\wood_detail_01 $detailscale 2.563 $detailblendfactor .8 $detailblendmode 0
Additionally, there are 2 other stock detail textures. detail\detailash001a and detail\detaildirt001a.
These files were used in the "leaked" version of Half-Life 2 & in Half-Life 2: Episode One using the following parameters;
(Concrete/concretefloor009a in Episode One materials)
$detail detail/detaildirt001a $detailscale 0.27
(Metal/metalfloor005a in Episode One materials)
$detail detail/detailash001a $detailscale 0.50
