A detail texture (noise_detail_01), and its effect when applied to a material.
$detail specifies a greyscale texture with which Source will add high-resolution detail when the material is viewed up close, by darkening the albedo appropriately. It is very effective for increasing the apparent resolution of a texture, and was used extensively in Episode Two.
Syntax
$detail <texture>
You will probably want to use at least $detailscale (see below) as well.
Additional parameters
While the additional $detail params are not strictly required, it is difficult to get good results without them.
$detailscale <float>- Fits the detail texture onto the material the given number of times. Generally around 7 or 8 for a 128px detail texture.
$detailblendfactor <normal>- Intensity of the detail's darkening of the albedo. Effectively an
$alphavalue. $detailblendmode <int?>- Todo: What are the modes?
$detailframe <int>- The frame of an animated texture to use. Requires DX9.
$detail_alpha_mask_base_texture <bool?>- Todo: Something to do with maskingRequires DX9.
$basetexturewith$detail's alpha channel?
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
There is also detail\wood_detail_01, but not stock material seems to use it.
