Warning:
CS:GO engine branch. Not enough data is stored in the vertices for normal mapping, so the engine has no choice but to fall back.

A material's albedo (left) compared to its bump map.
Template:Shaderparam It specifies a texture that will provide three-dimensional lighting information for a material. The texture is a bump map, but the process it is used for is called normal mapping. The two terms are often used interchangeably, however.
Warning:$bumpmap will disable prop_static's per-vertex lighting in every Source game before CS:GO engine branch. Not enough data is stored in the vertices for normal mapping, so the engine has no choice but to fall back.Note:
- In the
Watershader,$bumpmapis for a DX8 du/dv map. Use$normalmapinstead. - Bump maps cannot be used on decal textures except in CS:GO engine branch.
Basic Syntax
LightmappedGeneric
{
$basetexture brick/brickwall021a
$surfaceprop brick
$bumpmap brick/brickwall021a_normal
}
Additional Parameters
$bumptransform
$bumpframe
$nodiffusebumplighting
- Note:Functions with Template:Shaderparam but not regular normals on
Source 2013 .
[[$ssbump|$ssbump]]
$forcebump
$bump_force_on
$addbumpmaps
$bumpmap2
$bumpframe2
$bumptransform2
$bumpmask
$bumpdetailscale1
Console Commands
- mat_fastnobump <boolean>
- Quickly enables/disabled normal mapping.
- mat_normalmaps <boolean>
- Displays the bump map texture of all materials that have one in place of their albedo.
- (Yes, these two commands have bump and normal the wrong way around!)
- mat_bumpmap <boolean>
- Enable or disable normal mapping. Default 1.
