Es/$bumpmap

$bumpmap es un parámetro de un shader(en) disponible en todos los juegos de Source.

Un albedo(en) (izq.) comparado con un relieve.

El material de arriba en el juego.

Especifica una textura(en) que tendrá iluminación tridimensional e información para un material. La textura es un relieve(en), pero el proceso es un mapeado normal. Aunque ambos términos se utilizan indistintivamente.

Aviso:$bumpmap desactivará la iluminación por vértice de prop_static en los juegos Source previos a CS:GO rama de motor.
No hay mucha información en los vértices de un mapeado normal, por lo que el motor no tiene opción de retroceder.

Importante:$bumpmap no existe para LightmappedReflective(en). En su lugar se debe usar $normalmap.

Nota:

• En el sombreado Water(en), $bumpmap es para DX8 du/dv map(en). Se usa $normalmap en su lugar.
• Los relieves no se pueden usar sobre texturas adhesivas, excepto en CS:GO rama de motor.
• On VertexLitGeneric using $lightwarptexture will force bumpmapping even if $bumpmap is not in the VMT. A default one is bound instead, all $bumpmap caveats come with it.

Error: $bumpmap causes some other Parameters to not work. Parameters that will break with $bumpmap are ( but not limited to ) :

• Will not work with materials using $envmapmask. Except on VertexLitGeneric(only in ) and LightmappedGeneric(only in ). See Alternative methods.
• In LightmappedGeneric, $detailblendmode 9 cannot be used.
• In VertexLitGeneric, $detailblendmode 5, 6, 8, 9, 10 and 11 not usable. With $phong 5 and 6 can be used.
• In VertexLitGeneric, $detailblendmode 5-11 not usable. With $phong 5 and 6 can be used.
• In $detailtint won't work.
• $distancealpha, $outline, $softedges won't work.
• On LightmappedGeneric, cannot be used with $basealphaenvmapmask

Parámetros adicionales

$bumptransform(en) <matrix(en)> (DX9 SM2)

Transforms the bump map texture.

Pendiente: Does this actually require DX9? Present in DX8 fallback shaders.

Error:Does not work when using $detail. This does work in .  [todo tested in ?]

The default position is center .5 .5 scale 1 1 rotate 0 translate 0 0.

1. center defines the point of rotation. Only useful if rotate is being used.
2. scale fits the texture into the material the given number of times. 2 1 is a 50% scale in the horizontal X axis while the vertical Y axis is still at original scale.
3. rotate rotates the texture counter-clockwise in degrees. Accepts any number, including negatives.
4. translate shifts the texture by the given numbers. .5 will shift it half-way. 1 will shift it once completely over, which is the same as not moving it at all.

Nota:All values must be included!

Error:Scaling the texture may cause odd issues where the Texture Lock tool in Hammer will not actually lock the texture in place.  [todo tested in ?]

Error:Rotating textures applied on brushes will rotate around the map origin (confirm: Orangebox engine only?). A fix for this is to change the center position in the VMT to the brush's origin.  [todo tested in ?]

$bumpframe(en) <integer(en)>

The frame to start an animated bump map on.

$nodiffusebumplighting(en) <boolean(en)>

 Shader(s): LightmappedGeneric, Lightmapped_4WayBlend, WorldVertexTransition

Stops the bump map affecting the lighting of the material's albedo(en), which help combat overdraw. Does not affect the specular(en) map, making it useful for distorted reflections on flat surfaces.

Error:Does not function beyond Source 2007.^[confirmar]  [todo tested in ?]

Nota:Functions with $ssbump(en) but not regular normals on Source 2013 . More testing required?

$ssbump(en) <boolean(en)> (en todos juegos desde )

 Shader(s): LightmappedGeneric, Lightmapped_4WayBlend, WorldVertexTransition

Flags the bump map texture(s) as being self-shadowing. Click for more details.

$forcebump(en) <boolean(en)> (DX8) (eliminado desde )

If 0, use bumpmapping if the card says it can handle it. If 1, always force bumpmapping on.

$bump_force_on(en) <boolean(en)> (en todos juegos desde )

 Shader(s): LightmappedGeneric, Lightmapped_4WayBlend, WorldVertexTransition

Force bump mapping on, even for low-end machines.

$addbumpmaps(en) <boolean(en)> (only in )

 Shader(s): LightmappedGeneric

Enables the usage and blending of two bump maps together for LightmappedGeneric.

$bumpmap2(en) <texture(en)> (DX9 SM2)

 Shader(s): LightmappedGeneric, Lightmapped_4WayBlend, WorldVertexTransition

The second bump map to use, either for WorldVertexTransition or for LightmappedGeneric in for bump map blending.

$bumpframe2(en) <integer(en)> (DX9 SM2)

 Shader(s): LightmappedGeneric, Lightmapped_4WayBlend, WorldVertexTransition

Same as $bumpframe, but for the second bump map.

$bumptransform2(en) <matrix(en)> (DX9 SM2)

 Shader(s): LightmappedGeneric, Lightmapped_4WayBlend, WorldVertexTransition

Same as $bumptransform, but for the second bump map.

Nota:$detail used with $detailscale will override this on LightmappedGeneric if the shader is using $addbumpmaps.

$bumpmask(en) <texture(en)> (DX9 SM2)

 Shader(s): LightmappedGeneric

If using two bump maps, use a third bump map to act as the base, with the alpha channel acting as a mask for the first two bump maps. The alpha channel of $bumpmask is also used as a specular mask.

Nota:Only used by materials/nature/toxicslime002a.

Nota:Does not work with $detail and $seamless_scale.

$bumpdetailscale1(en) and $bumpdetailscale2(en) <normal(en)> (only in )

 Shader(s): LightmappedGeneric

The strength of the first and second bump maps for bump map blending.
