Bug: $detail textures do not work in conjunction with some parameters:
Confirm:are these limited to 
, or are they in some/all –branch games?
Confirm:Is SolidEnergy available in –branch games?
Note:$detail1tint and $detail2tint do not exist on this Shader, they are missing in this list intentionally!

GoldSrc, see Detail textures (GoldSrc)
GoldSrc, see Detail textures (GoldSrc)
A detail texture (noise_detail_01), and its effect when applied to a material (brickwall031a).
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 
Half-Life 2: Episode Two.
Bug: $detail textures do not work in conjunction with some parameters:
- In
on LightmappedGeneric, Does not work with $seamless_scale. - In on VertexLitGeneric. Does not work with $selfillumfresnel, if $bumpmap is used.
- In on LightmappedGeneric, Does not work with $lightwarptexture
- Note:
- In , LightmappedGeneric does not appear to even have $lightwarptexture as a parameter... So it 'cannot not' work.
- In on VertexLitGeneric, Does not work with $desaturatewithbasealpha
- In , Does not work with $blendmodulatetexture and $bumpmap
- In
- Todo: Document issues from other branches of source.
- Confirm: Things that don't work in , usually don't work in
either. And vice versa. But it'd be better if someone could confirm this.
- Note: Using $detail with $blendmodulatetexture will cause a graphical issue (stripes over the surface), only works correctly 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 (1024×1024), 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 and 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
